+On GNU/Linux it will try to run program ldconfig with the library installation
+directory as only argument. Failure to do so will not abort installation.
+One may disable ldconfig by ./configure option --disable-ldconfig-at-install .
+
+
+By use of a version script, the libisoburn.so library exposes no other function
+names but those of the API definitions in <libisoburn/libisoburn.h> and
+<libisoburn/xorriso.h>.

+The ./configure script of libisoburn can check via pkg-config whether suitable
+libburn and libisoburn are installed. Regrettably this test failed on several
+systems due to local pkg-config problems. So it is disabled by default and may
+be enabled by:
+   ./configure --enable-pkg-check-modules
+In this case, ./configure fails if no suitable installations are found.
+
+
+                              xorriso
+
+libisoburn comes with a command line and dialog application named xorriso,
+which offers a substantial part of libisoburn features to shell scripts and
+users. Its file xorriso/README_gnu_xorriso describes the tarball of the
+derived package GNU xorriso as first preference for a statically linked
+xorriso installation.
+The libisoburn installation described above produces a dynamically linked
+xorriso binary depending on libburn.so, libisofs.so, libisoburn.so.
+
+After installation documentation is available via
+    man xorriso
+    man xorrisofs
+    man xorrecord
+
+Several alias links point to the xorriso binary:
+    xorrisofs  starts xorriso with -as mkisofs emulation already enabled
+    xorrecord  starts xorriso with -as cdrecord emulation already enabled
+    osirrox    starts with -osirrox image-to-disk copying already enabled
+
+By default xorriso will depend on libreadline if the readline-dev headers
+are present. This dependcy can be avoided by running
+    ./configure --prefix=/usr --disable-libreadline
+    make clean ; make
+Never omit the "make clean" command after switching libreadline enabling.
+Other deliberate dependency reduction options of ./configure are:
+    --disable-libacl   avoid use of ACL functions like acl_to_text()
+    --disable-xattr    avoid use of xattr functions like listxattr() on Linux
+                       resp. extattr_list_file() on FreeBSD
+    --disable-zlib     avoid use of zlib functions like compress2()
+    --disable-libjte   avoid use of libjte for -jigdo command
+
+xorriso allows to use external processes as file content filters. This is

-libisoburn includes a command line and dialog application named xorriso,
-which offers a substantial part of libisoburn features to shell scripts and
-users.
-After installation its documentation is available via
-    man xorriso
+                      xorriso C language API
 
+Actually the dynamically linked xorriso binary is only a small start program
+for the xorriso API that is implemented inside libisoburn.
+There are API calls for command readers and interpreters, and there are
+API calls for each single command of xorriso.
+
+Interested programmers should have a look into the API definition at
+  xorriso/xorriso.h
+and the start program
+  xorriso/xorriso_main.c
+
+The header file  xorriso.h  gets installed suitable for
+  #include <libisoburn/xorriso.h>
+
+So after installation of a binary libisoburn package you may find it e.g. as
+  /usr/include/libisoburn/xorriso.h
+
+
+             xorriso under control of a (GUI) frontend process
+
+The dialog mode allows frontend programs to connect via pipes to the standard
+input and output of xorriso. Several commands of xorriso help with receiving
+and parsing of reply messages.
+
+As a proof of concept, there is the Tcl/Tk script xorriso-tcltk which can
+be launched by this shell command:
+
+    xorriso-tcltk
+
+Or in the xorriso build directory, without installation of xorriso:
+
+    xorriso/xorriso -launch_frontend frontend/xorriso-tcltk --stdio --
+
+In the running GUI, click with the rightmost mouse button on any GUI element
+to get its particular help text. The "Help" button at the upper right corner
+gives a short introduction and instructions for some common use cases.
+See also file frontend/README-tcltk.
+See its Tcl code for getting an idea how this gets achieved.
+
+The script is part of the tarball and gets installed by make install. If a
+xorriso distro package does not install it, you may get it directly from
+  http://libburnia-project.org/export/head/libisoburn/trunk/frontend/xorriso-tcltk
+
+Further there is the C program frontend/frontend_pipes_xorriso.c which
+forks a xorriso process and shows the same communication gestures as
+xorriso-tcltk.
+In particular it connects to xorriso via two pipes, sends commands, waits
+for all replies of a command, picks info out of the xorriso message sieve,
+and parses reply message lines into words.

 A possible source of problems are hald or other automounters. 
 If you can spot a process "hald-addon-storage" with the address of
 your desired drive, then consider to kill it.
+A similar process "udisks-daemon: polling ..." can be seen on newer Linuxes.
 
-If you cannot get rid of the automounter that easily, try whether it helps
-to always load the drive tray manually before starting a write run of
-xorriso. Wait until the drive light is off.
-Better try to unmount an eventually mounted media before a write run.
+On Debian GNU/Linux 6.0.2 amd64 there is
+  /lib/udev/rules.d/80-udisks.rules
+where one can remove all CD drives ("sr*") from the list of automountable
+devices:
+  KERNEL=="sd*|hd*|mmcblk*|mspblk*", ENV{UDISKS_PRESENTATION_NOPOLICY}="0"
+  # KERNEL=="sd*|hd*|sr*|mmcblk*|mspblk*", ENV{UDISKS_PRESENTATION_NOPOLICY}="0"
+Copying the recognition criterion from
+  /etc/udev/rules.d/70-persistent-cd.rules
+one can prevent automounting a single drive, too. E.g.:
+  SUBSYSTEM=="block", ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:11.0-scsi-2:0:0:0", ENV{UDISKS_PRESENTATION_NOPOLICY}:="1"
+
+If you cannot get rid of the automounter, try whether it helps to always load
+the drive tray manually before starting a write run of xorriso. Wait until the
+drive light is off and the mounted media appears.
+Then try to unmount the mounted media before a write run.

 We are quite sure that libisofs produces accurate representations of the disk

 test program which compares files from the mounted image with the orignals
 on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff.

+/**
+   @author Mario Danic, Vreixo Formoso, Thomas Schmitt
+
+   @mainpage Libisoburn Documentation Index
+
+   @section intro Introduction
+
+Libburnia is an open-source project for reading, mastering and writing
+optical discs. This page is about its capability to read, manipulate, and
+write ISO 9660 filesystems with Rock Ridge extensions. Media can be optical
+media or filesystem objects.
+
+Our scope is currently Linux 2.4 and 2.6, or FreeBSD, or OpenSolaris.
+
+libisoburn is an add-on to libburn and libisofs which coordinates both and
+also allows to grow ISO-9660 filesystem images on multi-session media as well
+as on overwriteable media via the same API.
+All media peculiarities are handled automatically.
+
+xorriso is an application of all three libraries which creates, loads,
+manipulates and writes ISO 9660 filesystem images with Rock Ridge extensions.
+Manipulation is not only adding or overwriting of files but also deletion,
+renaming, and attribute changing. An incremental backup feature is provided.
+The xorriso features are accessible via built-in command interpreters and
+via a C language API.
+
+
+SONAME:
+libisoburn.so.1 (since 0.1.0, February 2008).
+
+
+   @section using Using the libraries
+
+Our build system is based on autotools.
+User experience tells us that you will need at least autotools version 1.7.
+
+To build libisoburn go into its toplevel directory and execute:
+
+-  ./bootstrap  (needed if you downloaded from SVN)
+
+-  ./configure
+
+-  make
+
+To make the library and the xorriso application accessible for running resp.
+software development:
+
+-  make install
+
+
+For direct use as command line tool use the xorriso binary which among many
+other features provides a mkisofs emulation via command "-as mkisofs".
+See man page xorriso/xorriso.1 or GNU info document xorriso/xorriso.info.
+
+
+If you want to link an own application with libisoburn, you have
+two alternative APIs for choice:
+
+-  libisoburn, together with libburn and libisofs.
+
+-  xorriso, a complete representation of xorriso command line options.
+   It encapsulates the three lower level libraries.
+   Calls of both API families shall not be mixed.
+
+For a description of the lbisoburn API read libisoburn/libisoburn.h
+See file README for download and installation of a release tarball.
+You will also have to install and understand the two libraries of the 
+Libburnia project which provide fundamental services:
+libburn is the library by which preformatted data get onto optical media.
+See libburn/libburn.h for its API description.
+libisofs is the library to handle ISO 9660 filesystems with Rock Ridge 
+extensions. Its API is described in libisofs/libisofs.h .
+
+For xorriso features see its man page xorriso/xorriso.1 or
+its GNU info document xorriso/xorriso.info.
+For the corresponding C language API see libisoburn/xorriso.h (resp.
+xorriso/xorriso.h in the build directory).
+The implementation this API is part of libisoburn.
+The xorriso command line tool gets installed as dynamically linked
+binary together with libisoburn.
+
+There is also a statically linked release named GNU xorriso.
+See xorriso/README_gnu_xorriso for its download and installation.

+
+===== What is the difference between cdrskin and xorriso ? ===== #diff_cdrskin_xorriso
+
+[wiki:Cdrskin cdrskin] is a dedicated emulator of program cdrecord, based on
+libburn. It tries to be as similar to cdrecord as is possible under that
+premise.
+
+[wiki:Xorriso xorriso] is an integrated tool which creates, loads, manipulates,
+and writes ISO 9660 filesystem images with Rock Ridge extensions.
+It is based on libburn, libisofs, and libisoburn. One of its features is
+the emulation of the corresponding tasks as done by mkisofs and cdrecord.
+
+===== What does that SCSI error message mean ? ===== #scsi_error
+
+Error messages labled as "SCSI" stem from the drive. They are codes of
+three hexadecimal numbers, like [3 0C 00]. The first number gives an overall
+classification of the problem. The other two numbers give the particular
+error description.
+
+libburn translates known error codes into text messages. They consist of
+two statements: the overall classification and the error description.
+
+E.g. [3 0C 00] Medium error. Write error.
+
+The classification allows a guess where the problem cause might sit:
+
+2 "Drive not ready" : This is a well normal drive state and should be handled
+by libburn. If you see this outside of DEBUG messages then it happened
+at an unexpected occasion. Either libburn did its job wrong, or the hardware
+suffers from blackouts. Hardware can be: drive, cable, bus controller.
+
+Workaround: Check cables. If possible, try the drive at a different
+bus controller.
+
+3 "Medium error" : This indicates a problem between drive and medium. libburn
+cannot directly cause such an error by any mistake. If drive and medium
+are balancing on the edge of defect, it is possible that optional settings
+can cause or prevent such errors. But in many cases of drive-medium conflicts
+it is mere incident whether a burn run succeeds or not.
+
+Workaround: Try other media or another drive.
+
+4 "Drive error" : The drive or the bus controller accuse themselves of
+doing it wrong. As with "Medium error" this might be aggravated or eased by
+optional settings.
+
+Workaround: Check cables. If possible, try the drive at a different
+bus controller.
+
+5 "Illegal request" : The drive did not like a command sent by libburn.
+This may be normal. But if you see this outside of DEBUG messages, then
+either the drive does not comply to MMC or libburn does not do its job right.
+
+Workaround: Submit an error report to
+[http://mailman-mail1.webfaction.com/listinfo/libburn-hackers/ libburn-hackers mailing list].
+
+B "Command aborted" : Seems to be generated by some bus controllers or
+operating system SCSI drivers.
+
+Workaround: Contact
+[http://mailman-mail1.webfaction.com/listinfo/libburn-hackers/ libburn-hackers mailing list]
+and be ready for experiments.

+'''Imaging'''
+----------------------------------------------------------------------------
+
+===== Is there a way to edit files inside the ISO image ? ===== #edit_files
+
+File content cannot be altered. But files may be replaced by new copies from
+the disk filesystem.
+
+The main method of manipulating an existing ISO image is to append a session
+with a new complete directory tree and the file content of the added or
+overwritten files. Depending on the media type you get gaps between sessions
+of up to 20 MB. So better try to do all foreseeable changes by one add-on
+session.
+
+===== For which architectures xorriso is able to create bootable images ? ===== #boot_arch
+
+Currently it supports systems with PC-BIOS via El Torito for booting from
+CD, DVD, or BD media, and via MBR for booting from memory sticks or hard
+disks. Further it supports machines with MIPS processor from SGI (Big Endian)
+and DEC (Little Endian), and SUN SPARC machines.
+(See [http://bazaar.launchpad.net/%7Elibburnia-team/libisofs/scdbackup/annotate/head%3A/doc/boot_sectors.txt libisofs/doc/boot_sectors.txt]
+for technical details.)
+
+Machines which support EFI may either boot via El Torito or use the files
+of the ISO image directly. It is possible to append to the ISO image a
+writeable FAT12 partition where files for EFI may be stored and changed.
+
+===== How to enable booting from USB stick ? ===== #isohybrid
+
+The ISOLINUX boot loader is normally started from CD, DVD or BD media
+by a PC-BIOS via an El Torito boot record. But if the ISO image resides on an
+USB stick or another hard-disk-like device, then PC-BIOS ignores El Torito
+and rather expects a Master Boot Record (MBR). Both boot record types can
+reside in the same ISO image. Therefore it is possible to create an MBR that
+starts the boot image file of ISOLINUX which is already target of the El Torito
+boot record. This kind of MBR is called "isohybrid". ISOLINUX provides
+a program named isohybrid to patch existing images, but libisofs can create an
+MBR already when producing the ISO image. See in
+[http://www.gnu.org/software/xorriso/man_1_xorriso.html manual page of xorriso] 
+option -boot_image with arguments "isolinux" "system_area=",
+and -as mkisofs option -isohybrid-mbr.
+
+See [http://en.wikipedia.org/wiki/Master_boot_record Wikipedia on MBR] for
+general information about PC-DOS Master Boot Records, and
+[http://syslinux.zytor.com/wiki/index.php/ISOLINUX ISOLINUX wiki] for special
+information about ISOLINUX. The wiki example with mkisofs can be performed
+as well by help of xorriso option -as mkisofs.
+
+A similar combination of El Torito and MBR is created by GRUB2 tool
+grub-mkrescue. See [http://www.gnu.org/software/grub/ homepage of GNU GRUB 2]
+for general information.
+
+===== What is partition offset feature all about? ===== #partition_offset
+
+If an MBR is present, then it contains a partition table with up to four
+entries. The MBR is located at the very start of the ISO image. By
+tradition the first partition should begin only after the range of MBR and
+eventual supporting data blocks. On hard disk one often sees partition 1
+starting at byte 63*512. Further it is tradition that the payload filesystem
+is mountable via one of the partitions.
+
+The isohybrid MBR has its only partition start at byte 0. Thus it is mountable
+but does not obey the tradition to begin only after the MBR. The grub-mkrescue
+MBR on the other hand has partition 1 start at byte 512, which makes it
+unmountable. Only the unpartitioned base device can be mounted. (On GNU/Linux
+e.g. /dev/sdb is the base device whereas /dev/sdb1 is partition 1.)
+
+The compromise offered by libisofs is to create a second superblock at
+address 16*2048 and to let start partition 1 at this address. The second
+superblock leads to a second directory tree which takes into account the
+address difference between partition 1 and the base device. So the image
+gets mountable via both devices and reserves 32 kB for boot manager software
+where it may manipulate and augment the MBR.
+(See [http://libburnia-project.org/wiki/PartitionOffset Partition Offset Wiki]
+for examples.)
+
+There are reports of machines which will not boot from USB stick if
+partition offset is 0.
+
+===== Partition offset bad on Apple ? ===== #partition_offset_apple
+
+Apple's "Snow Leopard" operating system refuses to mount Debian CD images
+with non-zero partition offset.
+
+The issue is still under investigation. But for now one has to choose
+between mountability on Apple "Snow Leopard" or bootability from USB stick
+on Kontron CG2100 "carrier grade server".

+===== I want to write a GUI on the top of libburnia libraries. Any pointers or recommendations ? ===== #gui_advise
+
+Most appreciated would be a GUI for xorriso which allows to copy files from
+a view of the hard disk filesystem to a view of the ISO filesystem, and vice
+versa. The xorriso implementation is located inside libisoburn.
+
+Each option that is described in
+[http://www.gnu.org/software/xorriso/man_1_xorriso.html man 1 xorriso]
+can be performed by a corresponding C function that is defined in
+[http://libburnia-project.org/browser/libisoburn/trunk/xorriso/xorriso.h xorriso.h].
+Further there are calls for library startup and shutdown, for problem
+handling, and for the interpreters of xorriso's command line interface.
+The xorriso API encapsulates calls to libisofs, libburn, and libisoburn.
+
+An alternative to the xorriso C API is xorriso dialog mode.
+[#xorriso_dialog_mode See below.]
+
+The known existing GUIs [http://www.xfce.org/projects/xfburn/ Xfburn],
+[http://projects.gnome.org/brasero/ Brasero],
+[http://flburn.sourceforge.net/ FlBurn]
+rather use libisofs and libburn directly.

+
+
+===== What personalities are supported by xorriso ? ===== #xorriso_aliases
+
+The name by which xorriso is started may trigger certain features which
+normally would need to be enabled by program options.
+
+xorrisofs starts up in mkisofs emulation mode, which otherwise would have to
+be entered by command -as "mkisofs".
+
+xorrecord starts up in cdrecord emulation mode, which is normally entered by
+command -as "cdrecord". This emulation is only able to write a single data
+track as new session to blank or appendable media. No audio. No multiple
+tracks in one session.
+
+osirrox allows to copy files from ISO image to disk and to apply option -mount
+to one or more of the existing ISO sessions. This is normally enabled by
+option -osirrox "on:o_excl_off".
+
+===== What is xorriso dialog mode useful for ? ===== #xorriso_dialog_mode
+
+Dialog mode is initiated if -dialog "on" is among the program arguments.
+It can be used to inspect and exploit existing ISO 9660 images or
+to explore xorriso's behavior in order to develop the command sequence
+for a batch run.
+
+Frontend programmers may fork xorriso initiating a xorriso dialog session
+(-dialog "on" -use_readline "off" -pkt_output "on" -mark "done"),
+and interact with it from their own program via pipes connected to
+xorriso's stdin and stdout. This is more efficient than forking xorriso
+every now and then to perform various commands in order to complete
+complex tasks like image size prediction.
+
+===== Why is every second release missing ? ===== #version_numbers
+
+Releases have an even third version number. Like 0.5.6 or 1.0.4.
+During development the next higher odd number is used. E.g. 0.5.7 or 1.0.5.
+
+The content of release tarballs does not get changed without changing
+their name. The development tarballs of xorriso and cdrskin may change
+their content without notice.

+
+The partition offset feature of libisofs can produce ISO 9660 images which bear
+a quite conventional partition table if copied onto a USB stick. The first
+partition marks the size of the ISO image but starts at a non-zero address.
+Thus it marks a small part of the device as unclaimed by partitions and
+available for storing boot loader code.
+
+Nevertheless the USB stick is mountable via its overall device file as well as
+via the partition device file. E.g. on GNU/Linux: /dev/sdb and /dev/sdb1.
+This is achieved by two distinct sets of meta-data which refer to the same
+file content.
+
+The dual-mount feature supports Rock Ridge and Joliet too.
+It is capable of multi-session.
+
+Currently only offset 32 kB seems to make sense. Smaller offsets are prohibited
+by fundamental assumptions of libisofs and libisoburn. Larger offsets would
+extend the unclaimed area into vital blocks of the ISO image.
+
+--------------------------------------------------------------------------
+
+Meanwhile Debian
+[http://cdimage.debian.org/cdimage/daily-builds/daily/current/ daily]
+and [http://cdimage.debian.org/cdimage/weekly-builds/ weekly] builds make
+use of this feature with their bootable ISO images for i386 and amd64. E.g. 
+[http://cdimage.debian.org/cdimage/daily-builds/daily/current/i386/iso-cd/debian-testing-i386-businesscard.iso debian-testing-i386-businesscard.iso].
+
+According to a
+[http://syslinux.zytor.com/archives/2011-March/016201.html thread of march 2011]
+on Syslinux mailing list this enabled booting of a Kontron CG2100 server
+from USB stick, which otherwise failed.
+
+Regrettably the feature seems to prevent mounting of ISO 9660 images on
+Apple "Snow Leopard" systems.
+At least this is the outcome of a
+[http://lists.debian.org/debian-cd/2011/04/msg00029.html debian-cd thread of april 2011].
+
+--------------------------------------------------------------------------
+
+Example:
+
+Testing mountability and ISOLINUX bootability from USB stick and CD.
+
+Overview:
+
+The test image was derived from one year old RIPLinux-9.3-non-X.iso which
+has an isohybrid MBR. Syslinux version seems to be 3.82. That MBR and the file
+tree from the mounted RIPLinux image was used to build a new ISO image
+with 16 * 2kB partition offset. Isohybrid MBR patching was done by xorriso.
+
+Details:
+
+The first 32 kB of an ISO 9660 image are called System Area and may host any
+byte pattern. In the case of RIPLinux-9.3-non-X.iso only the first 512 bytes
+are non-zero. But to avoid any assumptions, all 32 kB get copied here.
+{{{
+  dd if=RIPLinux-9.3-non-X.iso bs=1K count=32 of=RIPLinux-9.3-non-X.sysarea
+}}}
+Normally the System Area file with its MBR is provided by the Syslinux
+installation under the name isohdp[fp]x*.bin .
+E.g. /usr/lib/syslinux/isohdpfx.bin
+
+The files of the image are made accessible for reading
+{{{
+  mount -o loop RIPLinux-9.3-non-X.iso /mnt
+}}}
+
+A new ISO image gets composed. The first three lines of arguments are taken
+from the prescriptions of ISOLINUX wiki and adapted to the names used in
+RIPLinux-9.3-non-X.iso.
+Option -isohybrid-mbr imports the copied System Area and patches the MBR
+according to rules published by hpa on Syslinux mailing list.
+Option -partition_offset 16 causes the first partition to start at 2 kB block
+number 16. It also prepares the image to be mountable by this partition, too.
+{{{
+  xorriso -as mkisofs \
+     -o new_image.iso \
+     -b boot/isolinux/isolinux.bin -c boot/boot.cat \
+     -no-emul-boot -boot-load-size 4 -boot-info-table \
+     -isohybrid-mbr RIPLinux-9.3-non-X.sysarea \
+     -partition_offset 16 \
+     /mnt
+}}}
+The image was copied onto a USB stick
+{{{
+  dd if=new_image.iso of=/dev/sdc
+}}}
+and plugged into a Debian system.
+{{{
+  fdisk -lu /dev/sdb
+}}}
+yields
+{{{
+   Device Boot      Start         End      Blocks   Id  System
+/dev/sdb1   *          64      120831       60384   17  Hidden HPFS/NTFS
+}}}
+
+I can mount /dev/sdb and /dev/sdb1 alike:
+{{{
+  mount /dev/sdb1 /mnt1
+  mount -o loop /dev/sdb /mnt
+}}}
+-o loop avoids failure with "mount: /dev/sdb already mounted or /mnt busy".
+A comparison by
+{{{
+  diff -r /mnt /mnt1
+}}}
+reports no difference.
+Human readable files look ok.
+Test-reading all content by
+{{{
+  tar cf - /mnt | wc
+}}}
+yields a reasonable byte count of 60743680 and no errors.
+
+The machine boots RIPLinux from this USB stick with no visible problems.
+It can then mount /dev/sdb as well as /dev/sdb1.
+The ISO image boots from CD too.
+
+Mounting the partition can be simulated with an image file on hard disk by
+cutting off the first partition_offset blocks of 2 KB:
+{{{
+  dd if=new_image.iso of=partition_image.iso bs=2048 skip=16
+  mount -o loop partition_image.iso /mnt1
+}}}
+
+--------------------------------------------------------------------------
+
+Another test was made with GRUB 2 by downloading
+{{{
+  bzr branch http://bzr.savannah.gnu.org/r/grub/trunk/grub
+}}}
+
+Before building GRUB 2, the file
+{{{
+  util/grub-mkrescue.in
+}}}
+was edited to replace in the options of the xorriso command:
+{{{
+  --protective-msdos-label
+}}}
+by
+{{{
+  -partition_offset 16 -no-pad
+}}}
+Then GRUB 2 was built and installed.
+
+The resulting image from
+{{{
+  ./grub-mkrescue -o image.iso
+}}}
+was put onto USB stick. It passed the same tests on Debian
+as above RIPLinux example. It boots to a GRUB prompt.
+
+Due to option -no-pad the image is about 250 kB smaller than
+the image produced by original grub-mkrescue. Else it would have grown by
+about 50 kB.
+
+Unpadded ISO images are safe except for burning on CD in TAO mode.
+In this case problems may occur with reading the last few data blocks.
+So when burning onto CD make sure to require SAO mode and/or to
+require padding by 300 kB.
+Burning on DVD or BD needs no such caution. Neither does copying
+on USB stick or hard disk.
+
+Program fdisk will complain about "different physical/logical" addresses.
+This can be silenced by adding option
+{{{
+ -partition_cyl_align on
+}}}
+at the cost of image padding up to the next full MB.
+E.g. by 402 kB to 2 MB.
+
+--------------------------------------------------------------------------
+
+Open questions:
+
+- Shall the partition of an isohybrid image be marked bootable ?
+Currently xorriso keeps the 0x80 mark of an imported MBR
+resp. the 0x80 mark which xorriso sets by its own MBR
+preparations.
+  - If not to be marked bootable:
+    What equipment would the partition need to justify having the mark ?
+
+------------------------------------------------------------------------
+
+Application:
+
+The partition offset feature can be controlled by libisofs API calls
+{{{

+
+As stated above, an offset larger than 16 would expose vital parts of the
+ISO image as unclaimed space. Values smaller than 16 are not accepted.
+So use either an offset of 16 blocks or keep the feature disabled by
+offset 0.

+This text describes how to set up a qemu virtual machine so that xorriso
+on its guest GNU/Linux can operate a CD, DVD or BD recorder of the host
+system.
+
+The options follow proposals of Paolo Bonzini on qemu-devel mailing list.
+My compliments for his patient guidance.
+
+Basic knowledge about Debian and qemu was learned from
+[http://www.gnu.org/s/hurd/hurd/running/qemu.html GNU Hurd qemu page].
+
+----------------------------------------------------------------------
+This start command works with with qemu-1.0-rc3:
+
+{{{

+    -cdrom .../some_image.iso
+}}}
+
+With this setup of -drive and -device it is necessary to have a
+medium in the drive, when qemu gets started. Else it will refuse.
+
+The guest system is accessible via ssh and scp at port 5557 of the
+host system.
+
+'''/dev/sr2''' is the address of the DVD drive which is handed over to the
+guest system.
+
+'''.../some_image.iso''' may be any readable file which shall serve as
+virtual DVD-ROM. qemu is not happy without such a thing.
+
+'''/dvdbuffer/i386-install.qemu''' is the disk image, where the guest operating
+system was installed by:
+{{{
+  $ qemu-img create /dvdbuffer/i386-install.qemu 8G
+  $ qemu \
+    -enable-kvm \
+    -m 512 \

+    -hda /dvdbuffer/i386-install.qemu \
+    -cdrom debian-6.0.3-i386-netinst.iso \
+    -boot d
+}}}
+
+Host system of my test is Debian GNU/Linux 6.0.2 amd64,
+which had access to the Internet when the guest was installed.
+
+----------------------------------------------------------------------
+
+Preparations on guest system Debian GNU/Linux 6.0.3 i386
+
+There appears no /dev/sr for the passthrough drive. Thus libburn will not
+list it by its drive search function. One may use it nevertheless. But
+xorriso will only do so if prefix "mmc:" is used with the address:
+{{{
+  -dev mmc:/dev/vda
+}}}
+The drive will be listed by libburn if there is a symbolic link /dev/sr*
+pointing to it. On Debian 6, this link persists only if it is created
+by an udev rule.
+
+In /lib/udev/rules.d/50-udev-default.rules:
+{{{
+    KERNEL=="vda", SYMLINK+="sr1"
+}}}
+
+libburn on Linux needs rw-permission for the drive's device node.
+The virtual device /dev/vda is in group "disk". Usual for CD drives is
+group "cdrom", to which i (or the Debian installer ?) have added my
+normal user when i installed the guest system.
+Like with the symbolic link, such a change persists on Debian 6 only as
+udev rule.
+
+In /lib/udev/rules.d/91-permissions.rules:
+{{{
+    KERNEL=="vda", GROUP="cdrom"
+}}}
+
+This should yield

+
+If your distro's xorriso is too old, consider to get and build GNU xorriso.
+{{{

+Do
+{{{

+  $ ./configure && make
+}}}
+Either do as superuser
+{{{
+  # make install
+}}}
+or execute it where it was built as
+{{{
+  $ ./xorriso/xorriso ...arguments...
+}}}
+After compilation, this binary does not depend on files in the build
+directory. You may move it to any other location.
+
+For details about the following xorriso commands, read
+{{{
+  man xorriso
+  man ./xorriso/xorriso.1
+}}}
+or with the same content
+{{{
+  info xorriso
+  info ./xorriso/xorriso.info
+}}}
+Or read the [http://scdbackup.sourceforge.net/man_1_xorriso_devel.html online man page of xorriso].
+
+
+Note that the sequence of xorriso arguments matters. They are commands
+which get performed one after the other.
+This differs from the behavior of mkisofs, cdrecord, et.al.,
+which parse all arguments and then perform actions in a hardcoded
+sequence.
+
+Writing happens automatically if ISO filetree changes are pending
+at the end of the program run. This is like with other burn tools.
+(There is a command -commit for intermediate writing e.g. in dialog
+mode.)

+
+Listing accessible drives:
+{{{
+  $ xorriso -devices

+
+The burn tests are presented here for unformatted DVD-RW media.
+The xorriso commands apply also to other types of optical media.
+See "Other applicable media types:" further below.
+
+----------------------------------------------------------------------
+
+Inspecting drive and medium:
+{{{
+  $ xorriso -outdev /dev/sr1 -toc
+}}}
+should show on stdout something like
+{{{

+}}}
+
+----------------------------------------------------------------------
+
+Blanking to single session capability:
+
+This medium has to be blanked before further writing. For the DAO
+test, one can save time by fast blanking, which xorriso normally
+dislikes because the result is not capable of multi-session:
+{{{
+   $ xorriso -outdev /dev/sr1 -blank deformat_quickest
+}}}
+should report on stderr
+{{{

+   Media current: DVD-RW sequential recording
+   Media status : is blank
+   Media summary: 0 sessions, 0 data blocks, 0 data, 4489m free
+}}}
+Do not worry if the pacifier messages show no neat percentage progress.
+Some drives report "1.0%" until they are done. Some report "1.0%"
+after "99%".
+
+----------------------------------------------------------------------
+
+Writing a DAO session:
+
+Use one or more moderately sized directories as input. Here: /usr/bin.
+Terminate the list of -add arguments by argument "--".
+It is important to have command -close "on" among the arguments.
+{{{
+  $ xorriso -md5 on -outdev /dev/sr1 -close on -add /usr/bin --
+}}}
+should report on stderr
+{{{

+
+Blanking to multi-session capability:
+{{{
+  $ xorriso -outdev /dev/sr1 -blank as_needed
+}}}
+This will need as long as writing the DVD-RW up to its end.
+Blanking option "as_needed" lets xorriso decide what to do in order
+to make the medium writable from scratch. With DVD-RW it will decide for
+-blank "all".
+
+The report on stderr should end by
+{{{

+}}}
+
+----------------------------------------------------------------------
+ 
+Writing multiple sessions (DVD-RW write type Incremental):
+
+This time do not perform command  -close "on", so that the medium
+stays writable:
+{{{
+  $ xorriso -md5 on -dev /dev/sr1 -add /usr/lib --
+  ...
+  xorriso : UPDATE : Writing:   105280s   98.6%   fifo   0%  buf  77%  3.5xD

+}}}
+Checkread like after the DAO test:
+{{{
+  $ xorriso -md5 on -indev /dev/sr1 -check_md5_r sorry / --
+  ...
+  xorriso : UPDATE :  204.0m content bytes read in 63 seconds
+  File contents and their MD5 checksums match.
+}}}
+Writing the second session looks like the first one. Just use another
+set of input files to get a visible change in the ISO 9660 file tree:
+{{{
+  $ xorriso -md5 on -dev /dev/sr1 -add /usr/bin --
+  ...
+  Written to media  : 53408 sectors at LBA 135488
+  Writing to '/dev/sr1' completed successfully.
+}}}
+And checkread the whole tree of files (i.e. both sessions):
+{{{
+  $ xorriso -md5 on -indev /dev/sr1 -check_md5_r sorry / --
+  ...
+  xorriso : UPDATE :  307.8m content bytes read in 89 seconds
+  File contents and their MD5 checksums match.
+}}}
+At the end of writing a final session, the medium can be closed.
+It will not take more writing unless it gets blanked or formatted.
+So use command -close "on" to demand closing after writing.
+{{{
+  $ xorriso -md5 on -dev /dev/sr1 -close on -add /usr/sbin --
+  ...
+  Written to media  : 16160 sectors at LBA 195056
+  Writing to '/dev/sr1' completed successfully.
+}}}
+Checkread
+{{{

+  ...
+  xorriso : UPDATE :  337.7m content bytes read in 97 seconds
+  File contents and their MD5 checksums match.
+}}}
+
+-----------------------------------------------------------------------------
+
+If the drive tray can move by itself, you may now eject the medium:
+{{{
+  $ xorriso -outdev /dev/sr1 -eject all
+}}}
+
+-----------------------------------------------------------------------------
+
+Other applicable media types:
+
+These test runs for sequential DVD-RW may be performed on CD-RW with the
+same xorriso arguments. Be aware that /usr/lib will hardly fit on a CD.
+So choose smaller directories for CD.
+
+-blank "deformat_quickest" addresses a peculiarity of DVD-RW.
+It will work on other media like -blank "fast".
+
+Except the blanking runs, the tests may also be performed on BD-R, DVD-R,
+DVD+R, and CD-R. But you would waste two media by this.
+
+The first session on CD will always be written with write type SAO,
+further sessions will be written with TAO.
+
+CD-R and DVD-R have a simulation mode. It can be enabled by xorriso
+command -dummy "on", but of course it will not produce readable results.
+So this simulation is usable only for first sessions on blank media.
+
+-----------------------------------------------------------------------------
+
+Now for formatted overwritable media:
+
+All blank, write and check runs of above tests "Writing multiple sessions"
+may also be performed with DVD+RW, DVD-RAM, formatted DVD-RW, and BD-RE.
+There is no way to close formatted media. The command -close "on"
+gets silently ignored.
+
+The write methods and states of formatted media differ from those of
+sequential media. But xorriso presents to the user a unified
+multi-session usage model, under the assumption that all emulated
+sessions contain ISO 9660 filesystem images, which successively
+build on each other.
+
+So from the view of xorriso commands, the only task which makes
+them differ from sequential media, is to apply optional formatting
+or re-formatting.
+A special case are BD-R, which xorriso may format but will not bring
+into (pseudo-) overwritable state. Formatted BD-R perform Defect
+Management by default, which checkreads during writing and replaces
+bad block.
+
+The mandatory formatting of unused DVD+RW and BD-RE is done by xorriso
+automatically. Just start a normal write run. DVD-RAM are sold formatted.
+
+xorriso treats overwritable media with a valid ISO 9660 filesystem as
+appendable media. To make then writable from scratch, apply
+-blank "as_needed", which will actually write a few bytes into the PVD
+(superblock) of the ISO filesystem to invalidate it.
+
+De-formatting is only possible with DVD-RW. E.g. by -blank "deformat".
+
+-----------------------------------------------------------------------------
+
+Format DVD-RW for overwriting without intermediate blanking,
+or format BD-R for Defect Management:
+{{{
+  $ xorriso -outdev /dev/sr1 -format as_needed 
+}}}
+should report on stderr
+{{{
+  ...
+  xorriso : UPDATE : Formatting  ( 99.0% done in 912 seconds )
+  Formatting done
+  xorriso : NOTE : Re-assessing -outdev '/dev/sr1'
+  Drive current: -outdev '/dev/sr1'
+  Media current: DVD-RW restricted overwrite
+  Media status : is blank
+  Media summary: 0 sessions, 0 data blocks, 0 data, 4488m free
+}}}
+As with blanking, one should not worry if the progress messages show
+unplausible percentages. Some drives are more equal than others.
+
+Formatting is said to be much stress to the medium. -format option
+"as_needed" applies it only to yet unformatted media.
+
+When performing above write tests, take care to use -blank "as_needed"
+rather than -blank "deformat_quickest". Else you will get a sequential
+unformatted DVD-RW rather than a formatted DVD-RW which xorriso is
+willing to write from scratch.
+There is no use in a separate "DAO" test on overwritable media anyway.
+
+-----------------------------------------------------------------------------
+
+Change the formatted size of a BD-RE:
+
+First learn about formatted size and proposals of other sizes.
+(One can issue own wishes, too. See in man xorriso, command -format.)
+{{{
+  $ xorriso -outdev /dev/sr1 -list_formats
+}}}
+should tell on stdout
+{{{
+  ...
+  Format status: formatted, with 23610.0 MiB
+  BD Spare Area: 0 blocks consumed, 131072 blocks available
+  Format idx 0 : 00h , 11826176s , 23098.0 MiB
+  Format idx 1 : 01h , 11564032s , 22586.0 MiB

+  Format idx 5 : 31h , 12219392s , 23866.0 MiB
+}}}
+So lets go back from 23610.0 MiB to the default size of 23098.0 MiB
+{{{
+  $ xorriso -outdev /dev/sr1 -format by_index_2 -blank as_needed
+  ...
+  Media summary: 2 sessions, 105470 data blocks,  206m data, 22.4g free
+}}}
+Although the heads of the old sessions might remain readable after
+-format, better do not rely on this and a append -blank "as_needed" to
+avoid any data corruption.
+If you want to keep the data, then make at least a checkread run.
+
+Check whether the size has changed:
+{{{
+  $ xorriso -outdev /dev/sr1 -list_formats
+}}}
+should tell on stdout
+{{{
+  ...
+  Format status: formatted, with 23098.0 MiB

+
+xorriso-tcltk is mainly a proof of concept for a frontend that operates
+xorriso in dialog mode.
+
+Dependencies:
+- xorriso ISO 9660 Rock Ridge filesystem manipulator and CD/DVD/BD burn program
+- Tcl programming language
+- Tk widget toolkit
+- optionally the Tcl/Tk package BWidget
+
+It exercises several fundamental gestures of communication:
+- connecting via two pipes
+- sending commands
+- receiving replies
+- inquiring the xorriso message sieve
+- using the xorriso parsing service
+
+Note that any other language than Tcl/Tk could be used, if it only can
+do i/o via standard input and standard output or via named pipes.
+Further it has to perform integer arithmetics and string manipulations.
+And, well, a graphical widget set would be nice.
+
+See man xorriso for a documentation of xorriso concepts and commands.
+See man xorrecord for details of the burn image file feature.
+
+
+                             Quick start
+
+In the xorriso build directory, without installation of xorriso:
+
+  xorriso/xorriso -launch_frontend frontend/xorriso-tcltk --stdio --
+
+After installation of xorriso by make install:
+
+  xorriso-tcltk
+
+
+                            Overview of GUI
+
+The window is separated into three main areas:
+- Connection to xorriso.
+- Management of drives and image files.
+- Inspection, manipulation, and exploitation of xorriso ISO image model.
+
+Click the rightmost mouse button while being over any of the GUI elements
+in order to get the particular help text for that element.
+There is no need to close the help window. Just click another element to
+get another help text.
+
+The "Help" button in the upper right corner gives a short overview and
+instructions for several common use cases.
+
+
+                         Program start options
+
+The Tcl shell "wish" is allergic to options which start by "-h".
+So here is the output of  xorriso-tcltk --help :
+------------------------------------------------------------------------
+
+Usage:
+  /usr/bin/xorriso-tcltk [options]
+Options:
+ All options must be given with two dashes ("--option") in
+ order to distinguish them from any options of the Tcl shell.
+ --help
+     Print this text and exit.
+ --stdio
+     Establish connection to xorriso via stdin and stdout.
+     E.g. when letting xorriso start this frontend program:
+       xorriso -launch_frontend $(which xorriso-tcltk) --stdio --
+ --named_pipes cmd_fifo reply_fifo
+     Establish connection to a xorriso process started by:
+       xorriso -dialog on <cmd_fifo >reply_fifo
+     which is then ready for a run of:
+       xorriso-tcltk --named_pipes cmd_fifo reply_fifo
+     It is important that the parent of xorriso and of this
+     tcl/tk frontend opens the named pipe for commands before
+     it opens the named pipe for replies. This avoids deadlock.
+ --silent_start
+     Do not issue the start message xorriso-tcltk-version.
+     This works only if --silent_start is the first argument.
+ --no_extract
+     Do not allow extraction of files from ISO filesystem to
+     hard disk. This is not revokable during the program run.
+ --no_bwidget
+     Do not try to load the Tcl/Tk package BWidget which is
+     a prerequisite for the "/" file browser buttons.
+ --geometry {+|-}X{+|-}Y
+     Sets the position of the main window.
+ --click_to_focus
+     Chooses that input fields and list boxes get the keyboard
+     focus only when being clicked by the mouse. (Default)
+ --auto_focus
+     Chooses that the keyboard focus is where the mouse
+     pointer is.
+ --pipe_log_file path
+     Set a file address for logging of xorriso commands and
+     reply messages and enable this logging.
+     The log lines will be appended. Path "-" means stderr.
+ --script_log_file path
+     Set a file address for logging of major xorriso commands
+     and enable this logging.
+     The log lines will be appended. Path "-" means stderr.
+
+If neither --stdio nor --named_pipes is given, then this script
+will try to locate itself in the filesystem and start a xorriso
+run that launches it again.
+
+In the running GUI, click with the rightmost mouse button on
+any GUI element to get its particular help text.

+libisoburn/releng. By George Danchev <danchev@spnet.net>
+                  and Thomas Schmitt <scdbackup@gmx.net>
+
+Test suite for xorriso and libburnia libraries.
+Copyright (C) 2011 - 2012 George Danchev, Thomas Schmitt
+Provided under GPL version 2 or later.
+------------------------------------------------------------------------------
+
+The impatient tester will build libisoburn according to its README and then do
+
+  cd ./releng
+  ./run_all_auto -x ../xorriso/xorriso
+
+More patient testers will first read the following description.
+
+Those who simply lack the interpreter /bin/bash, may do
+  ./change_shell_to_use
+and then retry.
+
+
+                            The test suite
+
+Directory ./releng of libisoburn contains a collection of test scripts and
+auxiliary data. They exercise some typical use cases of building libisoburn
+applications and running the ISO 9660 filesystem manipulation and CD/DVD/BD
+burn program xorriso. 
+
+It is assumed that libburn and libisofs are installed, so that libisoburn
+can be configured and built. It is not mandatory that libisoburn is already
+installed. The tests may use an installed xorriso program as well as a
+freshly built one.
+
+The test scripts explicitely demand /bin/bash as interpreter, although they
+would run on certain other shells too. If you get an error message like
+  ./run_all_auto: not found
+then consider to install /bin/bash.
+If you decide against that, see below "Alternative Shells".
+
+
+There are two groups of test scripts:
+
+  auto_*    gets started and watched by script run_all_auto.
+            These tests have a moderate resource consumption and do
+            not cause mechanical movements of drive trays.
+
+  manual_*  gets started by the user if desired.
+            Manual tests may create larger sets of temporary files,
+            may download test data from the internet, may need
+            system privileges beyond the reach of a sandbox user,
+            and operate the mechanics of a CD drive.
+
+
+                       Running automated tests
+
+The test scripts expect to get run while the working directory is
+  ./releng
+of a libisoburn source tree. E.g.: libisoburn-1.1.4/releng
+They create all their temporary files underneath
+  ./releng/releng_generated_data 
+Some of these files are persistent between tests.
+Nevertheless it is safe to empty ./releng/releng_generated_data after
+tests are done. The directory itself must be kept.
+
+To run the unobtrusive automatic tests, build libisoburn and xorriso,
+go to directory ./releng, and execute
+
+  ./run_all_auto -x ../xorriso/xorriso
+
+or if you want to use an installed xorriso program:
+
+  ./run_all_auto -x $(which xorriso)
+resp.
+  ./run_all_auto -x $(type -p xorriso)
+
+There are several options which work with run_all_auto and any single test.
+  -x  absolute or relative path to xorriso binary to be run.
+  -k  keep self-generated data.
+  -c  cleanup temporary data kept from previous run and exit.
+  -f  simulate failure.
+  -h  print this help text.
+  --  end of general options, begin of test specific options.
+After option "--", there may be given options which are specific to
+particular manually executable test scripts. 
+
+
+                        Manually executable tests
+                 
+Currently there are the following tests which should have the attention of
+the user or require sysadmin considerations before they are run:
+
+./manual_devices -x ../xorriso/xorriso [-- [--dev device_file_to_use]
+                                        [--priv_cmd 'command [arg [arg ...]]']]
+  Exercises listing of all accessible optical drives and the examination of
+  a one of these drives. The user needs the permission to operate the CD
+  drives. This might involve the need for superuser authority.
+  The media tray of the examined drive will get loaded if it is not already.
+  If no option --dev is given, then the user gets asked which of the listed
+  drives to examine more closely.
+  If a privilege command and optional arguments are given with --priv_cmd,
+  then this command and arguments are used to launch the xorriso runs.
+  Command and arguments must be single words and be submitted altogether
+  as one single argument. On Solaris use: --priv_cmd pfexec
+
+./manual_burn -x ../xorriso/xorriso [-- [--dev device_file_to_use]
+                                        [--priv_cmd 'command [arg [arg ...]]']
+                                        [--what ...directory...] [--any_media]]
+  Burns the content of the directory given with --what onto re-usable
+  media: CD-RW, DVD-RW, DVD-RAM, DVD+RW, BD-RE.
+  Other media types get refused, unless option --any_media is given.
+  Data, which are possibly present on the media, get overwritten.
+  The result gets check read and compared with the state of the input
+  directory. MD5 mismatch causes a test failure. Differences to the directory
+  state are reported but still regarded as success.
+  If a privilege command and optional arguments are given with --priv_cmd,
+  then this command and arguments are used to launch the xorriso runs.
+  Command and arguments must be single words and be submitted altogether
+  as one single argument. On Solaris use:
+    --priv_cmd pfexec
+
+./manual_isojigdo -x ../xorriso/xorriso
+  Exercises the production of a bootable Debian GNU/Linux image and its Jigdo
+  files. This test downloads a Debian daily image for i386 of about 270 MB,
+  extracts its content and composes a new image. Thus it needs about 850 MB
+  of disk space in releng/releng_generated_data when unpacked. Adding the daily
+  image size itself, the total space used would peak at about 1.2 GB.
+  This test will only work with GNU xorriso or if libjte was installed already
+  when libisofs was built. Further it needs the program jigit-mkimage. Both
+  are part of package jigit, version >= 1.18, available at:
+    http://www.einval.com/~steve/software/JTE/
+  Currently jigit builds only in GNU environments.
+
+
+Any auto_* script can be run on its own. Some of them demand option -x.
+All general options are accepted.
+
+./auto_cxx
+  Not included in GNU xorriso.
+  Exercises inclusion of xorriso/xorriso.h and libisoburn/libisoburn.h
+  in C++ programs and linking of the libraries. It might be necessary
+  to set compiler options by shell variable CFLAGS before running the test.
+  It might be necessary to hand over the install directory of libburn and
+  libisofs in shell variable LD_LIBRARY_PATH.
+  E.g. if on FreeBSD the include headers libisofs.h , libburn.h are not found:
+    export CFLAGS="-I/usr/local/include"
+  E.g. on GNU/Hurd, where libburn and libisofs are not found by the linker:
+    export LD_LIBRARY_PATH="/usr/local/lib"
+
+./auto_isocontent -x ../xorriso/xorriso
+  Tests whether xorriso is able to record and restore two familes of
+  hard links.
+
+./auto_printsize -x ../xorriso/xorriso
+  Tests how long xorriso needs to compose a medium sized directory tree.
+  If programs mkisofs and/or genisomage are availaible, then the same test
+  is done with them.
+
+
+----------------------------------------------------------------------------
+
+                       What to do with FAIL results
+
+The text output of the automatic tests is recorded in file
+   releng_generated_data/log.run_all_auto
+
+Script ./run_all_auto will detect failure of particular tests and report
+lines from the log file which contain problem indicating keywords:
+  NEVER,ABORT,FATAL,FAILURE,MISHAP,SORRY,WARNING,HINT,FAIL,ERROR,WRONG
+
+If the program messages in log.run_all_auto do not explain the failure,
+please contact mailing list libburn-hackers@pykix.org .
+
+
+----------------------------------------------------------------------------
+
+                          Alternative Shells
+
+If you decided against installing /bin/bash, you may try to use your
+current $SHELL by running
+  ./change_shell_to_use
+which will modify the test scripts named run_all_auto , auto_* ,manual_*.
+
+Known to be suitable are the following shells
+  GNU/Linux: /bin/bash
+  FreeBSD 8: /bin/sh
+  Solaris:   /bin/bash , /bin/i86/ksh93
+In general, the shell should have Bourne shell ancestry.
+
+The script does not choose an interpreter explicitely and is safe to be run
+inline:
+  . ./change_shell_to_use
+One may set any interpreter path by running a sub shell and changing its
+variable SHELL. E.g. by:
+  ( SHELL=/bin/my_shell" ; . ./change_shell_to_use )
+
+
+----------------------------------------------------------------------------
+
+                          Creating a new test script
+
+If you want to provide an own test, manual or auto, then first invent a name
+for it
+  test_name="releng/manual_"...some.name...
+or
+  test_name="releng/auto_"...some.name...
+Then copy file releng/template_new to $test_name.
+Edit $test_name and process any line that begins by "# === TEMPLATE:".
+Do what the line prescribes and then remove it from the script. You are
+not done as long as such a line remains.
+
+Your test must not start if no file
+   ./inc/releng_getopts.inc
+exists, i.e. if the current working directory is not ./releng.
+If your test creates own files on disk, then it must do this underneath
+directory
+   ./releng_generated_data/$test_name (resp. $GEN_DATA_DIR, see below).
+
+In case of failure, issue a line to stdout that begins by the word "FAIL",
+followed by " : " and the name of the test (e.g. $SELF, see below).
+Make sure that the test script finally returns a non-zero exit value.
+This value should be between 1 and 28. Each type of failure should have its
+own exit value.
+Predefined are:
+  31 = Unknown option or unusable argument with known option
+  30 = Unexpected state of own directory for self generated files
+  29 = Not in ./releng directory or missing essential parts of ./releng
+
+When exiting prematurely, make sure to call function cleanup.
+
+
+               Variables, general options, helper functions
+
+The master script run_all_auto sets this variable:
+
+  RELENG_SCRIPT_RUN_BY_RUN_ALL_AUTO
+                    1=supervised, the script is run by run_all_auto script
+                    else=standalone, the script is run in standalone mode 
+
+The code piece inc/releng_getopts.inc should get executed inline at the
+start of a test script. It initializes the following variables and sets
+some of them according to the general options of the test suite:
+
+  SELF              basename $0
+
+  GEN_DATA_DIR      releng_generated_data/${SELF}
+
+  RELENG_XORRISO    Path to xorriso binary. "" or "0" means no xorriso.
+                    Default "0". Adjustable by option -x.
+
+  SIMULATE_FAILURE  0=normal operation, 1=test script shall simulate a failure.
+                    Default 0. Setable to 1 by option -f.
+
+  CLEANUP           0=do not cleanup temporary data, 1=normal operation
+                    Default 1. Setable to 0 by option -k.
+
+  SPECIFIC_HELP     0=normal operation, 1=print help text of script and exit 0
+                    Default 0. Setable to 1 by option -h.
+
+The code piece inc/releng_getopts.inc defines the following functions
+for use by the single tests:
+
+  standalone_or_supervised This is internally called routine to print out
+                           the running mode of the scripts - standalone,
+                           supervised by run_all_auto.
+			   No need to call it from the scripts themselves.
+
+  print_help        Prints the help text for general options.
+
+  check_for_xorriso [-x]
+                    Will exit with value 31 if no path to a xorriso binary
+                    was defined by option -x of ./run_all_auto or a single
+                    test.
+                    Option -x of check_for_xorriso additionally tests whether
+                    the given path leads to an executable program.
+
+  cleanup           Removes the directory tree GEN_DATA_DIR after making
+                    some safety checks.
+
+  boldify           Try to set the terminal mode for future output to a more
+                    noticable style of writing.
+  unboldify         Reset terminal mode to normal style of writing.
+
+
+                             Specific options
+
+Options which are specific to the test should begin with a double dash.
+They may have further arguments.
+Implement them in the prepared interpreter loop which begins after line
+  next_is=ignore
+
+Specific options shall only be interpreted by tests which get run manually.
+If you plan to introduce a specific option, look at the description of
+existing tests whether one of them would match your needs. In that case,
+please re-use the name of that existing option.

releng/TODO

@@ -0,0 +1,42 @@
+
+* Manpage examples turned into tests
+  Convert most examples from xorriso(1) manpage into tests.
+
+* Enhance 'auto_isocontent'
+  Extend it to use some more demanding directory tree.
+  MD5s should be checked.
+  All file types as of stat(2) should be tested.
+  Test various comparisons:
+  xorriso provides built-in means for comparison: 
+  xorriso -compare_r disk_path iso_rr_path
+  xorriso -indev my.iso -find /   vs. find input_dir
+  bsdtar -xf my.iso               vs. input_dir
+
+* Test for wrong CD sizes would need a new test and probably an
+  automatic CD changer.
+
+* Library unit tests - investigate the possibility to write some
+  cunit-based tests (http://cunit.sourceforge.net) for both
+  xorriso.h and libisoburn.h API's. The code samples could be put into
+  codesamples/ directory and run by auto_cxx or a separate auto_ script.
+
+* ??? Still to decide:
+  Delete debian-testing-i386-businesscard.iso with ./run_all_auto -c
+  Contra: Currently remaining large files (like downloaded ISO images) are
+  simply left behind to be re-used and a boldified info message is shown
+  so the users can decide for themselves what to remove or leave as well.
+  Pro: Leaving 70 MB of image is quite obtrusive. Option -c is not run
+  under normal circumstances. So it could well be used for total cleanup.
+  Alternative: Specific option --remove_image.
+
+* ??? Still to decide:
+  Have a script ./run_all_manual
+  Contra argument: if a releng sctipt is suitable to be run under a master
+  script run_all*, then this releng script should be put into auto_*
+  namespace , otherwise it is manual_*.
+  Pro: Tests may be manual because they demand lots of resources, not
+  because they need manual attention. In general the run_all_manual script
+  shall spare the user the plight to read the documentation. Instead it
+  shall present the manual tests, give an opportunity to skip the test,
+  and ask for parameters,

+#
+# The MD5 checksum of the file content must be encoded in 32 hex digits
+# [0-9afAF]
+#
+# Next come two blanks.
+#
+# The byte size of the file content must be encoded in 12 decimal digits
+# or blanks.
+#
+# Next come two blanks.
+#
+# The rest of the line up to the newline character is a semi-literal file
+# address. Its basename has to be the same as the basename of the data file
+# when it is used as one of the input files for the jigdo file generator.
+
+# The semi-literal address and the address mapping define what will be
+# listed as file address in the jigdo file.
+# The address may bear at its start a literal text that shall be recognized by
+# the address mapping (e.g. -jigdo-map) of the jigdo file generator.
+# The rest of the address must be usable as file address in both situations:
+# When the jigdo file gets generated, and when the jigdo file gets read
+# to inflate the template file into the original payload image.
+# The address mappings at both occasions can be used to adapt to a change
+# of the absolute location of the listed files.
+# Between both mappings, the parent directory is represented by a symbolic
+# text, like "Debian:".
+
+# A simple strategy to cope with this is to write absolute paths into the
+# .md5 file, and to use matching absolute paths in the -jigdo-map
+# directives. Keep in mind that mapping is purely literal. Symbolic links
+# are neither resolved nor can they confuse the mapping.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify

+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with

-xorriso. By Thomas Schmitt <scdbackup@gmx.net>
-Integrated sub project of libburnia-project.org but also published via:
-http://scdbackup.sourceforge.net/xorriso_eng.html

-Copyright (C) 2006-2008 Thomas Schmitt, provided under GPL version 2.

-
-
-xorriso is a program which maps file objects from POSIX compliant
-filesystems into Rock Ridge enhanced ISO 9660 filesystems and allows
-session-wise manipulation of such filesystems. It can load the management
-information of existing ISO images and it writes the session results to
-optical media or to filesystem objects.
-
-Currently it is only supported on Linux with kernels >= 2.4.
-
-A special property of xorriso is that it needs neither an external ISO 9660
-formatter program nor an external burn program for CD or DVD but rather
-incorporates the libraries of libburnia-project.org .
-
-By using this software you agree to the disclaimer at the end of this text:
-"... without even the implied warranty ..."
-
-
-                   Compilation, First Glimpse, Installation
-
-The most simple way to get xorriso is the xorriso standalone tarball.
-
-Prerequisites:
-The tarball contains anything that is needed except libc and libpthread.
-libreadline and the libreadline-dev headers will make dialog mode
-more convenient, but are not mandatory.
-
-Obtain xorriso-0.1.0.tar.gz, take it to a directory of your choice and do:
-
-    tar xzf xorriso-0.1.0.tar.gz
-    cd xorriso-0.1.0
-
-Within that directory execute:
-
-    ./configure --prefix=/usr
-    make
-
-This will produce a binary named
-    ./xorriso/xorriso
-
-which you may strip to reduce it in size
-    strip ./xorriso/xorriso
-
-You may copy or move it to a directory where it can be found by the shell,
-you may execute xorriso at the place where it was built, or you may execute
-as superuser:
-    make install
-
-For general concepts, options and usage examples see
-    man 1 xorriso
-
-This man page is part of the tarball as
-    xorriso/xorriso.1
-You may get a first glimpse by
-    man ./xorriso/xorriso.1
-
-It gets installed with "make install" but may also be placed manually in the
-./man1 directory below one of the directories mentioned in environment
-variable $MANPATH.
-
-
-                       Drives and Disk File Objects 
-
-The user of xorriso needs rw-permission for the CD burner device.
-A list of rw-accessible drives can be obtained by
-
-    xorriso -devices
-
-CD devices which offer no rw-permission are invisible to normal users.
-The superuser should be able to see any usable drive and then set the
-permissions as needed.
-
-The output of  xorriso -devices  might look like
-
-0  -dev '/dev/sr0' rwrw-- :  'TSSTcorp' 'CDDVDW SH-S203B' 
-1  -dev '/dev/hda' rwrw-- :  'HL-DT-ST' 'DVD-ROM GDR8162B' 
-
-Full and insecure enabling of both for everybody would look like
-    chmod a+rw /dev/sr0 /dev/hda
-This is equivalent to the traditional setup chmod a+x,u+s cdrecord.
-
-I strongly discourage to run xorriso with setuid root or via sudo !
-It is not checked for the necessary degree of hacker safety.
-
-Consider to put all authorized users into group "floppy", to chgrp the
-device file to that group and to disallow w-access to others.
-
-
-A possible source of problems are hald or other automounters. 
-If you can spot a process "hald-addon-storage" with the address of
-your desired drive, then consider to kill it.
-
-If you cannot get rid of the automounter that easily, try whether it helps
-to always load the drive tray manually before starting a write run of
-xorriso. Wait until the drive light is off.
-Better try to unmount an eventually mounted media before a write run.
-
-
-Besides true optical drives, xorriso can also address disk files as input or
-output drives. The addresses of the disk files have to be preceded by "stdio:".
-Like:
-    xorriso -dev stdio:/tmp/pseudo_drive ...more arguments...
-
-
-                              Testing
-
-We are quite sure that libisofs produces accurate representations of the disk
-files. This opinion is founded on a lot of test burns and checks by a little
-test program which compares files from the mounted image with the orignals
-on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff.
-
-This program is not installed systemwide but stays in the installation
-directory of the xorriso tarball as  test/compare_file . Usually it is
-run as -exec payload of a find command. It demands at least three arguments:
-The path of the first file to compare, the prefix1 to be cut off from path
-and the prefix2 which gets prepended afterwards to obtain the path of the
-second file to compare.
-As further argument there can be -no_ctime which suppresses the comparison
-of ctime date stamps.
-The exit value is 0 if no difference was detected, non-0 else.
-
-Example: After
-   xorriso ... -pathspecs on -add /=/original/dir --
-   mount /media/dvd
-   cd test
-compare tree /media/dvd with tree /original/dir :
-   find /original/dir -exec ./compare_file '{}' /original/dir /media/dvd ';' \
-   | less
-and vice versa:
-   find /media/dvd -exec ./compare_file '{}' /media/dvd /original/dir ';' \
-   | less
-
-
-                             libisoburn
-
-xorriso is based on libisofs which does ISO 9600 filesystem aspects and on
-libburn which does the input and output aspects. Parts of this foundation
-are accessed via libisoburn, which is closely related to xorriso.
-
-libisoburn provides two services:
-- Encapsulation of coordination between libisofs and libburn.
-- Emulation of ISO 9660 multi-session on overwriteable media
-  or random access files.
-
-The sourcecode of all three libraries is included in the xorriso standalone
-tarball. It is compiled with xorriso and linked statically.
-But you may as well get and install releases of libburn and libisofs, in order
-to be able to install a release of libisoburn which produces libisoburn.so.1
-and a matching dynamically linked xorriso binary.
-This binary is leaner but depends on properly installed libraries of suitable
-revision.
-
-Dynamic library and compile time header requirements for libisoburn-0.1.0 :
-- libburn.so.4  , version libburn-0.4.2 or higher
-- libisofs.so.6 , version libisofs-0.6.2 or higher
-libisoburn and xorriso will not start with libraries which are older than their
-headers seen at compile time. So compile in the oldest possible installation
-setup unless you have reason to enforce a newer bug fix level.
-
-Standalone xorriso has less runtime dependencies and can be moved more freely.

+      Contribution of libburnia-project.org to the GNU Operating System
+------------------------------------------------------------------------------
+GNU xorriso. By Thomas Schmitt <scdbackup@gmx.net>
+Derived from and supported by libburnia-project.org, published via:
+http://www.gnu.org/software/xorriso/xorriso_eng.html
+http://www.gnu.org/software/xorriso/xorriso-1.2.5.tar.gz

+xorriso is a program which copies file objects from POSIX compliant
+filesystems into Rock Ridge enhanced ISO 9660 filesystems and allows
+session-wise manipulation of such filesystems. It can load the management
+information of existing ISO images and it writes the session results to

+Vice versa xorriso is able to restore file objects from ISO 9660 filesystems.
+
+A special property of xorriso is that it needs neither an external ISO 9660
+formatter program nor an external burn program for CD or DVD but rather
+incorporates the libraries of libburnia-project.org .
+
+Currently it is fully supported on GNU/Linux with kernels >= 2.4,
+on FreeBSD with ATAPI/CAM support enabled in the kernel, see atapicam(4),
+and on OpenSolaris (tested with kernel 5.11).
+On other X/Open compliant systems there will only be POSIX i/o with disk
+file objects, but no direct MMC operation on CD/DVD/BD drives.
+
+By using this software you agree to the disclaimer at the end of this text:
+"... without even the implied warranty ..."
+
+
+                   Compilation, First Glimpse, Installation
+
+The most simple way to get xorriso from source code is the GNU xorriso tarball.
+
+Prerequisites:
+The tarball contains everything that is needed except the following system
+components:
+   libc, libpthread
+   plus on FreeBSD: libiconv, libcam, IDE and SATA drives need atapicam
+Optional at compile time are:
+   libreadline and the readline-dev headers make dialog mode more convenient.
+   zlib and zlib-devel allow zisofs compression.
+   on GNU/Linux: libacl and libacl-devel allow getting and setting ACLs.
+If they were present at compile time, then the optional libraries have to
+be present at runtime, too.
+
+Obtain xorriso-1.2.5.tar.gz, take it to a directory of your choice and do:
+
+    tar xzf xorriso-1.2.5.tar.gz
+    cd xorriso-1.2.5
+
+Within that directory execute:
+
+    ./configure --prefix=/usr
+    make
+
+This will produce a binary named
+    ./xorriso/xorriso
+
+If you want xorriso to report a "Build timestamp" with its option -version :
+    make buildstamped
+
+You may strip the binary to reduce it in size
+    strip ./xorriso/xorriso
+
+You may copy or move it to a directory where it can be found by the shell,
+or you may execute xorriso at the place where it was built,
+or you may execute as superuser:
+    make install
+
+For general concepts, options and usage examples see
+    info xorriso
+    info xorrisofs
+    info xorrecord
+or
+    man 1 xorriso
+    man 1 xorrisofs 
+    man 1 xorrecord 
+
+You may get a first glimpse by e.g.
+    info ./xorriso/xorriso.info
+    man ./xorriso/xorriso.1
+
+The installation creates several alias links pointing to the xorriso binary:
+    xorrisofs  starts xorriso with -as mkisofs emulation already enabled
+    xorrecord  starts xorriso with -as cdrecord emulation already enabled
+    osirrox    starts with -osirrox image-to-disk copying already enabled
+
+
+If you want to avoid dependecy on libreadline although the libreadline
+development package is installed, then rather build xorriso by:
+    ./configure --prefix=/usr --disable-libreadline 
+    make clean ; make
+Never omit the "make clean" command after switching libreadline enabling.
+Other deliberate dependency reduction options of ./configure are:
+    --disable-libacl   avoid use of ACL functions like acl_to_text()
+    --disable-xattr    avoid use of xattr functions like listxattr() on Linux
+                       resp. extattr_list_file() on FreeBSD
+    --disable-zlib     avoid use of zlib functions like compress2() 
+                       this also avoids the use of libjte and option -jigdo.
+
+xorriso brings own system adapters which allow burning optical media on
+GNU/Linux, FreeBSD, Solaris.
+Alternatively it can use libcdio-0.83 or later for sending commands to
+optical drives:
+    --enable-libcdio
+
+xorriso allows to use external processes as file content filters. This is
+a potential security risk which may be avoided by ./configure option
+    --disable-external-filters
+
+By default the filter feature is disabled if effective user id and real
+user id differ. This ban can be lifted by
+    --enable-external-filters-setuid
+
+Sometimes xorriso will yield better write performance on GNU/Linux if 64 KB are
+transmitted in each write operation rather than 32 KB. See option -dvd_obs .
+64k can be made default at configure time by:
+    --enable-dvd-obs-64k
+
+For xorriso -as cdrecord emulation only:
+In some situations GNU/Linux may deliver a better write performance to drives
+if the track input is read with O_DIRECT (see man 2 open). The included libburn
+and the cdrecord emulation of xorriso can be told to use this peculiar read
+mode by:
+    --enable-track-src-odirect
+
+Linux only:
+libburn tries to avoid a collision with udev's drive examination by waiting
+0.1 seconds before opening the device file for a longer time, after udev
+might have been alarmed by drive scanning activities.
+The waiting time can be set at ./configure time with microsecond granularity.
+E.g. 2 seconds:
+  CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=2000000"
+  ./configure ...options...
+Waiting can be disabled by zero waiting time:
+  CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=0"
+Alternatively, libburn can try to be nice by opening the device file,
+closing it immediately, waiting, and only then opening it for real:
+  CFLAGS="$CFLAGS -DLibburn_udev_extra_open_cyclE -DLibburn_udev_wait_useC=500000"
+
+
+             xorriso under control of a (GUI) frontend process
+
+The dialog mode allows frontend programs to connect via pipes to the standard
+input and output of xorriso. Several commands of xorriso help with receiving
+and parsing of reply messages.
+
+As a proof of concept, there is the Tcl/Tk script xorriso-tcltk which can
+be launched by this shell command:
+
+    xorriso-tcltk
+
+Or in the xorriso build directory, without installation of xorriso:
+
+    xorriso/xorriso -launch_frontend frontend/xorriso-tcltk --stdio --
+
+In the running GUI, click with the rightmost mouse button on any GUI element
+to get its particular help text.
+See file frontend/README-tcltk for a short introduction.
+See its Tcl code for getting an idea how this gets achieved.
+
+Further there is the C program frontend/frontend_pipes_xorriso.c which
+forks a xorriso process and shows the same communication gestures as 
+xorriso-tcltk.
+In particular it connects to xorriso via two pipes, sends commands, waits 
+for all replies of a command, picks info out of the xorriso message sieve, 
+and parses reply message lines into words.
+
+
+                       Drives and Disk File Objects 
+
+The user of libisoburn applications needs rw-permission for the CD/DVD/BD
+drives which shall be used, even if only reading is intended.
+A list of rw-accessible drives can be obtained by
+
+    xorriso -devices
+
+CD devices which offer not enough permission are invisible to normal users.
+The superuser should be able to see any usable drive and then set the
+permissions as needed.
+On Linux and FreeBSD, rw-permissions are needed.
+On Solaris, the privilege "sys_devices" and r-permission are needed.
+
+The output of  xorriso -devices  might look like
+
+0  -dev '/dev/sr0' rwrw-- :  'TSSTcorp' 'CDDVDW SH-S203B' 
+1  -dev '/dev/hda' rwrw-- :  'HL-DT-ST' 'DVD-ROM GDR8162B' 
+
+On Linux, full and insecure enabling of both for everybody would look like
+    chmod a+rw /dev/sr0 /dev/hda
+This is equivalent to the traditional setup chmod a+x,u+s cdrecord.
+
+On FreeBSD, device permissions are to be set in /etc/devfs.rules.
+On Solaris, pfexec privileges may be restricted to "basic,sys_devices".
+See below "System Dependent Drive Permission Examples".
+
+I strongly discourage to run xorriso with setuid root or via sudo !
+It is not checked for the necessary degree of hacker safety.
+Better consider to grant the necessary permissions to group "floppy"
+and to add users to it.
+
+
+A possible source of problems are hald or other automounters. 
+If you can spot a process "hald-addon-storage" with the address of
+your desired drive, then consider to kill it.
+A similar process "udisks-daemon: polling ..." can be seen on newer Linuxes.
+
+On Debian GNU/Linux 6.0.2 amd64 there is
+  /lib/udev/rules.d/80-udisks.rules 
+where one can remove all CD drives ("sr*") from the list of automountable 
+devices:
+  KERNEL=="sd*|hd*|mmcblk*|mspblk*", ENV{UDISKS_PRESENTATION_NOPOLICY}="0"
+  # KERNEL=="sd*|hd*|sr*|mmcblk*|mspblk*", ENV{UDISKS_PRESENTATION_NOPOLICY}="0"
+Copying the recognition criterion from
+  /etc/udev/rules.d/70-persistent-cd.rules
+one can prevent automounting a single drive, too:
+  SUBSYSTEM=="block", ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:11.0-scsi-2:0:0:0", ENV{UDISKS_PRESENTATION_NOPOLICY}:="1"
+
+If you cannot get rid of the automounter, try whether it helps to always load 
+the drive tray manually before starting a write run of xorriso. Wait until the 
+drive light is off and the mounted media appears.
+Then try to unmount the mounted media before a write run.
+
+
+Besides true optical drives, xorriso can also address disk files as input or
+output drives. By default paths to files under /dev are accepted only if the
+device represents a real optical drive. Other device files may be addressed
+by prepending "stdio:" to the path.
+Like:
+    xorriso -dev stdio:/dev/sdb ...more arguments...
+This rule may be changed by xorriso option -drive_class.
+Prefix "mmc:" causes a path to be accepted only if it is a real optical drive
+which is accessible by generic SCSI/MMC commands.
+
+
+                              Testing
+
+For automated and manual tests of xorriso's functionality see file
+  releng/README
+
+
+              Result comparison with self produced ISO images
+
+We are quite sure that libisofs produces accurate representations of the disk
+files. This opinion is founded on a lot of test burns and checks by a little
+test program which compares files from the mounted image with the orignals
+on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff.
+
+This program is not installed systemwide but stays in the installation
+directory of the xorriso tarball as  test/compare_file . Usually it is
+run as -exec payload of a find command. It demands at least three arguments:
+The path of the first file to compare, the prefix1 to be cut off from path
+and the prefix2 which gets prepended afterwards to obtain the path of the
+second file to compare.
+As further argument there can be -no_ctime which suppresses the comparison
+of ctime date stamps.
+The exit value is 0 if no difference was detected, non-0 else.
+
+Example: After
+   xorriso ... -pathspecs on -add /=/original/dir -- -commit_eject all
+   mount /media/dvd
+   cd test
+compare tree /media/dvd with tree /original/dir :
+   find /original/dir -exec ./compare_file '{}' /original/dir /media/dvd ';' \
+   | less
+and vice versa:
+   find /media/dvd -exec ./compare_file '{}' /media/dvd /original/dir ';' \
+   | less
+
+
+                             File Formats
+
+                             Sector Maps
+
+Sector maps describe the valid and invalid blocks on a media or a disk copy of
+a media. xorriso creates and reads these file with its option -check_media.
+
+The file begins with 32 bytes of cleartext of which the last one is a
+newline character. The first 25 say "xorriso sector bitmap v2 ", the
+remaining six characters give the size of the info text as decimal number.
+This number of bytes follows the first 32 and will not be interpreted
+by xorriso. They are rather to inform a human reader about the media type
+and its track layout.
+After the info text there are two 4 byte signed integers, most significant
+byte first. The first one, N, gives the number of bits in the following bitmap
+and the second number S gives the number of 2 KiB blocks governed by a single
+bit in the map. Then come the bits in form of 8-bit bytes.
+Data block M is covered by bit B=M/S in the map, bit number B is stored in
+byte B/8 as bit B%8. A valid readable data block has its bit set to 1.
+
+                             Checksum Tags
+
+Checksum tags are data blocks inside an ISO 9660 image which do not belong to
+any file but rather tell the MD5 of a certain range of data blocks.
+
+The superblock checksum tag is written after the ECMA-119 volume descriptors.
+The tree checksum tag is written after the ECMA-119 directory entries.
+The session checksum tag is written after all payload including the checksum
+array. (Then follows padding.)
+
+The tags are single lines of printable text, padded by 0 bytes. They have
+the following format:
+
+ Tag_id pos=# range_start=# range_size=# [session_start|next=#] md5=# self=#\n
+
+Parameters md5= and self= are 32 digit hex, the others are decimal numbers.
+
+Tag_id distinguishes the following tag types
+  "libisofs_rlsb32_checksum_tag_v1"     Relocated 64 kB superblock tag
+  "libisofs_sb_checksum_tag_v1"         Superblock tag
+  "libisofs_tree_checksum_tag_v1"       Directory tree tag
+  "libisofs_checksum_tag_v1"            Session end tag
+
+A relocated superblock may appear at LBA 0 of an image which was produced for
+being stored in a disk file or on overwriteable media (e.g. DVD+RW, BD-RE).
+xorriso records the first session at LBA 32. A follow-up session
+begins at the next block address which is divisible by 32 and higher than the
+address of the previous session's end tag. Normally no session starts after the
+address given by relocated superblock parameter session_start=.
+Session oriented media like CD-R[W], DVD-R, DVD+R, BD-R will have no relocated
+superblock but rather bear a table-of-content on media level.
+
+A tag is valid if pos= tells its own block address and self= tells its own MD5
+up to the last hex digit of md5=. range_start= tells the first block that is
+covered by md5=, range_size= tells the number of blocks covered by md5=.
+Relocated superblocks tell the block address of their session by session_start=.
+Superblock and tree tag tell the block address of the next tag by next=.
+The newline character at the end is mandatory.
+
+
+                             libisoburn
+
+xorriso is based on libisofs which does ISO 9660 filesystem aspects and on
+libburn which does the input and output aspects. Parts of this foundation
+are accessed via libisoburn, which is closely related to xorriso.
+
+libisoburn provides several services:
+- Encapsulation of coordination between libisofs and libburn.
+- Emulation of ISO 9660 multi-session on overwriteable media
+  or random access files.
+- Implementation of the xorriso API.
+
+The sourcecode of all three libraries is included in the xorriso standalone
+tarball. It is compiled with xorriso and linked statically.
+But you may as well get and install releases of libburn and libisofs, in order
+to be able to install a release of libisoburn which produces libisoburn.so.1
+and a matching dynamically linked xorriso binary.
+This binary is very lean but depends on properly installed libraries of
+suitable revision.
+
+Dynamic library and compile time header requirements for libisoburn-1.2.4 :
+- libburn.so.4  , version libburn-1.2.4 or higher
+- libisofs.so.6 , version libisofs-1.2.4 or higher
+libisoburn and xorriso will not start with libraries which are older than their
+headers seen at compile time. So compile in the oldest possible installation
+setup unless you have reason to enforce a newer bug fix level.
+
+GNU xorriso has less runtime dependencies and can be moved more freely.
+
+
+                  System Dependent Drive Permission Examples
+
+Accessing the optical drives requires privileges which usually are granted
+only to the superuser. GNU/Linux, FreeBSD and Solaris offer quite different
+approaches for avoiding the need for unrestricted privileges.
+
+First check whether some friendly system setting already allows you to
+access the drives as normal user:
+  xorriso -devices
+Those drives of which you see address and type strings are already usable.
+
+If there remain drives invisible which the superuser can see by the same
+command, then the following examples might help:
+
+---------------------
+On all three systems:
+---------------------
+Add the authorized users of CD drives to group "floppy" in /etc/group.
+If missing: create this group.
+Changes to /etc/group often only affect new login sessions. So log out and in
+before making the first tests.
+
+-------------
+On GNU/Linux:
+-------------
+Allow rw-access to the drives
+  chgrp floppy /dev/sr0 /dev/sr1
+  chmod g+rw   /dev/sr0 /dev/sr1
+It might be necessary to perform chgrp and chmod after each reboot or to
+edit distro dependent device configuration files for permanent settings.
+
+-----------
+On FreeBSD:
+-----------
+Edit /etc/devfs.rules and make sure to have these lines
+  [localrules=10]
+  add path 'acd*' mode 0664 group floppy
+  add path 'cd*' mode 0664 group floppy
+  add path 'pass*' mode 0664 group floppy
+  add path 'xpt*' mode 0664 group floppy
+  [localrules=5]
+  add path 'pass*' mode 0664 group floppy
+  add path 'cd*' mode 0664 group floppy
+  add path 'xpt*' mode 0664 group floppy
+  add path 'acd*' mode 0664 group floppy
+
+Edit /etc/rc.conf and add the following line if missing
+  devfs_system_ruleset="localrules"
+
+This gets into effect by reboot or by command
+  /etc/rc.d/devfs start
+
+-----------
+On Solaris:
+-----------
+Run xorriso by
+  pfexec xorriso ...arguments...
+
+The following settings will make pfexec keep original UID and EUID and prevent
+most superuser powers. Be aware that you still can manipulate all device files
+if you have the file permissions for that.
+Full root privileges for xorriso can then be acquired only by command su.
+
+Edit /etc/security/exec_attr and add this line to the other "Media Backup"
+lines:
+  Media Backup:solaris:cmd:::/usr/local/bin/xorriso:privs=basic,sys_devices
+Edit /etc/user_attr and add profile "Media Backup" to the user's line:
+  thomas::::profiles=Media Backup,Primary Administrator;roles=root
+See also man privileges, man exec_attr, man user_attr.
+
+Then allow the group r-access to the drives
+  pfexec chgrp floppy /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
+  pfexec chmod g+r    /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
+The last two commands have to be executed after each boot. I do not know
+the relevant device configuration files yet.
