+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+

+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

-   svn co http://libburn-svn.pykix.org/libburn/trunk libburn_pykix
-go into directory libburn_pykix and apply autotools by
-   ./bootstrap
+                                From tarball

-Alternatively you may unpack a release tarball for which you do not need

+Obtain libburn-1.1.4.tar.gz, take it to a directory of your choice and do:

-To build libburn.pykix.org and its subprojects it should be sufficient to go
-into its toplevel directory (here: "libburn_pykix") and execute
-   ./configure

+For a standalone cdrskin binary, see cdrskin/README.

-The other half of the project, libisofs, is hosted in the libburn SVN, too:

+A behavioral conflict is known between any burn software and demons like hald

+
+                        Special ./configure options
+
+make install on GNU/Linux 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
+
+In some situations Linux may deliver a better write performance to drives if
+the track input is read with O_DIRECT (see man 2 open). The API call
+burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
+can be told to use this peculiar read mode by:
+   --enable-track-src-odirect
+
+But often libburn call burn_write_opts_set_dvd_obs(opts, 64*1024) will yield
+even better performance in such a situation. 64k can be made default at
+configure time by:
+    --enable-dvd-obs-64k
+This may be combined with above --enable-track-src-odirect .
+
+Alternatively the transport of SCSI commands can be done via libcdio-0.83.
+You may install it and re-run libburn's ./configure with option
+    --enable-libcdio
+
+By use of a version script, the libburn.so library exposes no other function
+names but those of the API definition in libburn/libburn.h.
+If -Wl,--version-script=... makes problems with the local compiler, then
+disable this encapsulation feature by
+    --disable-versioned-libs
+
+Make sure to re-compile all source files after running ./configure
+   make clean ; make

+                        Overview of libburnia-project.org
+
+libburnia-project.org is an open-source software project for reading, mastering
+and writing optical discs.
+For now this means CD media, all DVD media, all BD media.

 The project comprises of several more or less interdependent parts which
 together strive to be a usable foundation for application development.
 These are libraries, language bindings, and middleware binaries which emulate
 classical (and valuable) Linux tools.
+Currently it is supported on GNU/Linux with kernels >= 2.4,
+on FreeBSD with ATAPI/CAM enabled in the kernel (see man atapicam),
+and on OpenSolaris (tested with kernel 5.11).
+On other X/Open compliant systems there will only be pseudo drives, but no
+direct MMC operation on real CD/DVD/BD drives.

-Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
-we would need : login on a development machine resp. a live OS on CD or DVD,
-advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
-volunteers for testing of realistic use cases.
+For full ports to other systems we would need : login on a development machine
+resp. a live OS on CD or DVD, advise from a system person about the equivalent
+of Linux sg or FreeBSD CAM, volunteers for testing of realistic use cases.

-We do have a workable code base for burning data CDs, though. The burn API is
-quite comprehensively documented and can be used to build a presentable
-application.
-We do have a functional binary which emulates parts of cdrecord in order to
-prove that usability, and in order to allow you to explore libburn's scope
-by help of existing cdrecord frontends.
+We have a well tested code base for burning data and audio CDs, DVDs and BDs.
+The burn API is quite comprehensively documented and can be used to build a
+presentable application.
+We have a functional application which emulates the core use cases of cdrecord
+in order to prove that usability, and in order to allow you to explore
+libburn's scope by help of existing cdrecord frontends.
+
+ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created
+and manipulated quite freely. This capability together with our burn capability
+makes possible a single binary application which covers all steps of image
+composition, updating and writing. Quite unique in the Linux world.

 The project components (list subject to growth, hopefully):

 - libburn  is the library by which preformatted data get onto optical media.
           It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
-           /dev/hdX (e.g. on kernel 2.6).
-           libburn is the foundation of our cdrecord emulation.
+           /dev/srM or /dev/hdX (e.g. on kernel 2.6).
+           libburn is the foundation of our cdrecord emulation. Its code is
+           independent of cdrecord. Its DVD capabilities are learned from
+           studying the code of dvd+rw-tools and MMC-5 specs. No code but only
+           the pure SCSI knowledge has been taken from dvd+rw-tools, though.

 - libisofs is the library to pack up hard disk files and directories into a
           ISO 9660 disk image. This may then be brought to CD via libburn.
-           libisofs is to be the foundation of our upcoming mkisofs emulation.
+           An own ISO 9660 extension stores ACLs, xattr, and MD5 of file
+           content.
+
+- 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.
+           It also contains the methods of command oriented application
+           xorriso and offers them via a C language API.

 - cdrskin  is a limited cdrecord compatibility wrapper for libburn.
-           Cdrecord is a powerful GPL'ed burn program included in Joerg
+           cdrecord is a powerful GPL'ed burn program included in Joerg
           Schilling's cdrtools. cdrskin strives to be a second source for
-           the services traditionally provided by cdrecord.
+           the services traditionally provided by cdrecord. Additionally it
+           provides libburn's DVD capabilities, where only -sao is compatible
+           with cdrecord.
           cdrskin does not contain any bytes copied from cdrecord's sources.
           Many bytes have been copied from the message output of cdrecord
           runs, though.
           See cdrskin/README for more.

- test     is a collection of application gestures and examples given by the
-           authors of the library features. The main API example for libburn
-           is test/libburner.c .
+- 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 deleting, renaming, attribute
+           changing, incremental backups, activating boot images, and
+           extracting of files from ISO images to disk. There is also a
+           sparse emulation of cdrecord and a more laborate one of mkisofs.
+           All features of xorriso are also available via a C language API
+           of libisoburn.
+           See xorriso/README for more.
+
+- "test"   is a collection of application gestures and examples given by the
+           authors of the library features. The burn API example of libburn
+           is named test/libburner.c . The API for media information inquiry is
+           demonstrated in test/telltoc.c .
           Explore these examples if you look for inspiration.

-We plan to be a responsive upstream. Bear with us. We are still practicing.
+We strive to be a responsive upstream.
+
+Our libraries are committed to maintain older feature sets in newer versions.
+This applies to source code headers (API) as well as to linkable objects (ABI).
+The only exception from this rule is about non-release versions x.y.*[13579]
+which are allowed to introduce new features, change those new features in
+any way and even may revoke such new features before the next release of
+x.y.*[02468]. As soon as it is released, a feature is promised to persist.
+
+SONAMES:
+libburn.so.4    (since 0.3.4, March    2007),
+libisofs.so.6   (since 0.6.2, February 2008),
+libisoburn.so.1 (since 0.1.0, February 2008).
+
+Applications must use 64 bit off_t. E.g. by defining
+#define _LARGEFILE_SOURCE
+#define _FILE_OFFSET_BITS 64
+or take special precautions to interface with the libraries by 64 bit integers
+where the .h files prescribe off_t. To reduce libburn's off_t size to 32 bit
+will keep it from processing tracks of more than 2 GB size.

 - 13th November 2006 splitting releases of libburn+cdrskin from libisofs.

+- 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has
+  become suitable for unaware frontends as long as they perform only the core 
+  of cdrecord use cases (including open-ended input streams, audio, and
+  multi-session).
+
+- 28th November 2006 the umbrella project which encloses both, libisofs and
+  libburn, is now called libburnia. For the origin of this name, see 
+  http://en.wikipedia.org/wiki/Liburnians .
+
+- 16th January 2007 release of libburn-0.3.0 and cdrskin-0.3.0 . Now the scope
+  is widened to a first class of DVD media: overwriteable single layer types
+  DVD-RAM, DVD+RW, DVD-RW. This is not a cdrecord emulation but rather inspired
+  by dvd+rw-tools' "poor man" writing facility for this class of media.
+  Taking a bow towards Andy Polyakov.
+
+- 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with
+  multi-session and with DAO.
+
+- 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer
+  DVD media. Code for double layer DVD+/-R is implemented but awaits a tester
+  yet.
+
+- 23th April 2007 version 0.3.6 follows the unanimous opinion of Linux kernel
+  people that one should not use /dev/sg on kernel 2.6.
+
+- 31st July 2007 version 0.3.8 marks the first anniversary of libburn revival.
+  We look back on improved stability, a substantially extended list of media
+  and write modes, and better protection against typical user mishaps.
+
+- 24th October 2007 version 0.4.0 is the foundation of new library libisoburn
+  and an upcomming integrated application for manipulating and writing
+  ISO 9660 + Rock Ridge images. cdrskin-0.4.0 got capabilities like growisofs
+  by these enhancements: growing of overwriteable media and disk files.
+  Taking again a bow towards Andy Polyakov.
+
+- 26th Januar 2008 version 0.4.2 rectifies the version numbering so that we
+  reliably release libburn.so.4 as should have been done since libburn-0.3.2.
+  cdrskin now is by default linked dynamically and does a runtime check
+  to ensure not to be started with a libburn which is older than itself.
+

+  It is the first release of new libisofs.so.6 which will guarantee future
+  API/ABI compatibility for its whole feature set.
+
+- 15th Feb 2008 libisoburn-0.1.0 (.so.1) coordinates libisofs and libburn for
+  the purpose of ISO image reading and writing. It emulates multi-session on
+  overwriteable media. Application xorriso makes use of all three libraries.
+

+  and read performance on disk file pseudo-drives has been improved.
+
+- 27th Apr 2008 libisofs-0.6.4 can now read data file content from images
+  and can map pieces of disk files onto image files. Image directory iteration
+  has been enhanced. Input data streams and extended information have been
+  exposed in the API to allow future development.
+
+- 29th Apr 2008 libisoburn-0.1.4 was made more efficient with reading of
+  image tree nodes. It now depends on libisofs-0.6.4 and libburn-0.4.4.
+  xorriso makes use of new libisofs features by performing incremental
+  updates of directory trees and by cutting oversized data files into
+  pieces. A primitive single session emulation of cdrecord and mkisofs is
+  provided.
+
+- 10th May 2008 libburn-0.4.6 supports formatting and writing of BD-RE,
+  full nominal speed for DVD-RAM and BD-RE. cdrskin has a unified blank
+  type with automatic media state recognition.
+
+- 17th May 2008 an old bug with DVD-RAM and now with BD-RE is fixed by
+  libburn-0.4.8 to allow libisoburn emulation of multisession on those media.
+
+- 19th May 2008 libisoburn-0.1.6 brings better table-of-content emulation
+  on overwriteble media and disk files.

+  and cdrecord style. xorriso now can serve underneath growisofs.
+
+- 20th Aug 2008 libburn-0.5.2 revokes the necessity that a drive must be
+  enumerable in order to be adressable. Enumeration is enhanced by examining
+  /proc/sys/dev/cdrom/info.
+  
+- 24th Aug 2008 libisoburn/xorriso-0.2.4 introduces a media readability check
+  with data retrieval option.
+
+- 18th Sep 2008 libisofs-0.6.8 supports ISO 9660 Level 3 which allows very
+  large data files in the image.
+
+- 20th Sep 2008 libisoburn/xorriso-0.2.6 takes into respect the new Level 3
+  capabilities of libisofs. 
+
+- 6th Oct 2008 libburn-0.5.4 adjusts the changes of 0.5.2 to the needs of
+  Linux kernel 2.4 and introduces human readable SCSI error messages.

+
+- 2nd Dec 2008 libisoburn-0.3.0. xorriso now is ready for exotic character
+  sets, for legacy FreeBSD systems which expect an outdated Rock Ridge
+  signature, and for producing ISO images with MBR which boot from hard disk
+  or USB stick. Three minor bugs were fixed.
+
+- 7th Dec 2008 libburn-0.5.8 prevents a SIGSEGV with wierd CD table-of-content
+  and improves BD-RE formatting.
+
+- 9th Dec 2008 Our project received a donation from Thomas Weber.

+  capabilities provided by libisofs for xorriso backup features.
+
+- 11 Mar 2009 libisofs-0.6.16 of libisofs fixes two bugs which on Solaris
+  prevented to navigate the ISO images by ".." and to recognize the Rock Ridge
+  extensions of ISO images. The ban to build libisofs on operating systems
+  other than Linux and FreeBSD has been lifted.
+
+- 13 Mar 2009 libburn-0.6.4 got a dummy adapter for SCSI/MMC command transport.
+  It will show no drives and thus libburn will only be able to perform
+  operations on "stdio:" pseudo drives. Nevertheless this allowed to lift the
+  ban to build libburn on operating systems other than Linux and FreeBSD.
+
+- 16 Mar 2009 libisoburn-0.3.6: xorriso uses RRIP version 1.10 as default 
+  in order to be mountable where mkisofs images are mountable.
+
+- 17 Apr 2009 libisofs-0.6.18 introduces content filtering of data files.
+  Built-in filters allow compression to formats gzip and zisofs. External

+  and a bug with device scan on FreeBSD.
+
+- 31 May 2009 libisofs-0.6.20 can record hard link relations in ISO images
+  and offers support with restoring them to disk. Current Linux kernels will
+  mount images with such hard links but will attribute a unique inode number
+  to each file.
+
+- 28 Jun 2009 libisoburn-0.4.0: xorriso can record and restore hard link
+  relations of files. Performance of data reading has been improved. Option
+  -find now supports logical operators with its tests.
+
+- 14 Jul 2009 libburn-0.6.8 fixes bugs and shortcommings with old MMC-1 drives
+  and with large SCSI bus numbers as handed out by Linux for USB drives.
+
+- 20 Jul 2009 libisoburn-0.4.0.pl01 fixes a regression in xorriso which caused
+  data loss in older sessions if xorriso was used underneath growisofs.
+  Affected are releases since libisoburn-0.3.2 in january 2009.
+
+- 25 Aug 2009 libisofs-0.6.22 can record MD5 checksums for the whole session
+  and for each single data file. Checksum tags allow to verify superblock and
+  directory tree before importing them.
+
+- 27 Aug 2009 libburn-0.7.0 allows to calm down a drive and to inquire its
+  supported profiles. It works around some pitfalls with U3 enhanced memory
+  sticks which emulate a CD-ROM.
+
+- 27 Aug 2009 libisoburn-0.4.0.pl00 can record MD5 checksums by which one may
+  verify the session or single data files in the image. When comparing image
+  files with files in the local filesystem, the MD5 sums avoid the need for
+  reading file content from the image.
+
+- 22 Sep 2009 libisoburn-0.4.0.pl01 fixes a bug in xorriso option -cut_out.
+
+- 08 Oct 2009 libisofs-0.6.24 fixes a bug which could cause the loss of blanks
+  in file names when a new session got added to an ISO image. With names
+  shorter than 251 characters this happened only to trailing blanks.
+
+- 08 Oct 2009 libisoburn-0.4.0.pl02 fixes bugs with xorriso option -for_backup,
+  with xorrisofs -help, and with xorrecord -help.
+
+- 12 Oct 2009 libburn-0.7.2 fixes a bug with CD TAO multi-track dummy sessions.
+  It can retrieve media product info and can process track input which was
+  prepared for CD-ROM XA Mode 2 Form 1. cdrskin now performs option -minfo.
+
+- 28 Oct 2009 libisoburn-0.4.4 fixes a bug with cdrecord emulation and
+  introduces new information options about media type and ISO image id strings.
+  On Linux it helps with mounting two sessions of the same media
+  simultaneously.
+
+- 12 Nov 2009 libburn-0.7.2.pl01 works around problems with Pioneer DVR-216D.
+  DVD-R runs made the drive stuck. Ejecting the tray did not work properly.
+
+- 06 Dec 2009 libburn-0.7.4 works around problems with newer DVD burners,
+  provides throughput enhancements with hampered busses on Linux, and new
+  API calls to log SCSI commands and to control the libburn fifo.
+
+- 09 Dec 2009 libisoburn-0.4.6 allows performance tuning of output to DVD
+  drives or disk files.
+
+- 26 Dec 2009 libburn-0.7.4.pl01 fixes the release tarball which was lacking
+  the files of the generic system adapter for X/Open.

+  computer which shall serve as OS farm for development and support.
+
+- 20 Jan 2010 Version 0.6.26 of libisofs fixes minor bugs and shall enhance
+  portability.
+
+- 22 Jan 2010 libburn-0.7.6 has an improved system adapter for FreeBSD,
+  fixes bugs about the generic X/Open system adapter, and allows to use
+  libcdio >= 0.83 as SCSI transport facility.
+
+- 10 Feb 2010 libisofs-0.6.28 fixes a regression about bootable images which
+  was introduced by version 0.6.22 in August 2009.
+
+- 23 Feb 2010 libisoburn-0.5.0 marks the transition of the xorriso standalone
+  version to an official GNU project. The name changed to "GNU xorriso" and its
+  license is now GPLv3+.
+  The licenses of libburnia libraries and applications are not affected by
+  this change. 
+
+- 10 Mar 2010 libburn-0.7.8 fixes bugs and improves the built-in abort handler
+  on FreeBSD.

+  images which were copied to a different start address than they were prepared
+  for.
+
+- Mon Jan 17 2011 we go for release 1.0.0. This does not indicate a
+  technological overhaul but shall emphasize the maturity of the software.
+  libisofs-1.0.0 fixes a bug about the length of ECMA-119 directory names and
+  is ready to allow untranslated ECMA-119 names (violating the specs).
+  libburn-1.0.0.pl00 allows umask to create stdio-drive files with
+  rw-permissions for all. cdrskin now refuses to burn if the foreseeable size
+  exceeds media capacity
+  libisoburn-1.0.0.pl00 allows to create an ISO 9660:1999 directory tree,
+  improved the emulation fidelity of command -as mkisofs, lowered the default
+  abort threshold for xorriso batch mode, and increased that threshold for
+  xorriso dialog mode.
+
+- Wed Feb 23 2011 release 1.0.2:
+  libisofs fixes several bugs and introduces the capability to copy files
+  inside the ISO filesystem.
+  libburn removed a compilation obstacle on Solaris 9 and improved recognition
+  of stdio pseudo-drives.
+  libisoburn and xorriso fix bugs and make use of the new libisofs capability.
+  xorriso improves its mkisofs emulation.
+
+- Thu Mar 10 2011 release 1.0.4:
+  Several bugs were fixed in the libraries and in the mkisofs emulation of
+  xorriso. This emulation xorrisofs has now an own man page and info document.
+
+- Sat Apr 09 2011 release 1.0.6:
+  libburn refined its representation of emulated drives. The size alignment
+  of DVD DAO is now 2 kB rather than 32 kB. libisofs produces Joliet names of
+  up to 103 characters. xorriso fixes two bugs and makes use of the library
+  improvements.
+
+- Thu Apr 14 2011 release libisoburn-1.0.8:
+  A bug in the mkisofs emulation of xorriso could cause options to be ignored.
+  The problem was freshly introduced with libisoburn-1.0.6. 
+
+- Fri May 13 2011 release libisofs-1.0.8:
+  Fixes a few rarely occurring bugs that have been found during the last month.
+
+- Sat Jun 18 2011 release 1.1.0:
+  The consumption of stack memory was reduced. Statical program analysis found
+  some rarely occuring memory leaks. Several small bugs were fixed.
+  The suffix .plXY was dropped from tarball names of libburn and libisoburn.
+
+- Mon Jun 20 2011 patch release libburn-1.1.0.pl01:
+  libburn-1.1.0 compiled only on Linux, FreeBSD, and Solaris, but not on
+  other X/Open compliant systems.
+
+- Fri Jul 08 2011 release libisofs-1.1.2 and libisoburn-1.1.2:
+  A severe regression was fixed in libisoburn and xorriso, which was introducedi
+  with version 1.0.6. It caused ISO 9660 images to be unreadable if they were
+  written to a write-only random-access file. E.g. by: xorrisofs ... >image.iso
+  
+- Sun Aug 07 2011 release libiburn-1.1.4 and libisoburn-1.1.4:
+  Several bugs were fixed in libburn. The most severe of them prevented xorriso
+  on some drives from burning mountable ISO 9660 images to CD media.
+  New means to list drives by their udev symbolic links help to deal with
+  non-persistent drive addresses on modern GNU/Linux.

-Don't blame me or other authors of libburn if anything goes wrong.
+Currently it is supported on GNU/Linux with kernels >= 2.4,

+IDE drives under Linux 2.4. need kernel module ide-scsi.
+ATA and SATA drives under FreeBSD need kernel module atapicam.
+On other X/Open compliant systems there will only be emulated drives, but no

+libburn, which is a control software for optical drives according to standard
+MMC-5. For particular CD legacy commands, standards MMC-3 and MMC-1 apply.

 cdrskin does not contain any bytes copied from cdrecord's sources. Many bytes

-                              Drive Addressing
-
-Drives get addressed either via their cdrecord-style addresses as listed
-with option -scanbus (see below "Pseudo-SCSI Adresses") or via the paths
-of device files.
-Not only device files listed by --devices may be used but also device files
-which via their major,minor numbers point to the same device driver as
-a listed device file. 
-
-Helpful with Linux kernel 2.4 is a special SCSI feature:
-It is possible to address a scsi(-emulated) drive via associated device files
-which are not listed by option --devices but point to the same SCSI addresses
-as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is
-compatible with generic read programs like dd and with write program growisofs.
-
-                             Pseudo-SCSI Adresses
-
-cdrecord and cdrskin share the syntax of SCSI addresses but not necessarily
-the meaning of the components. A cdrecord-style address for cdrskin
-  [prefix:]scsibus,target,lun
-can be interpreted in two different modes.
-
-Standard mode tries to be compatible to original cdrecord. This should be true
-with (emulated) SCSI where the /dev/sgN with is looked up with matching
-scsibus,target,lun as given by the operating system.
-With dev=ATA: or dev=ATAPI: the translation to /dev/hdX is purely literal
-but matches the cdrecord addresses on all systems tested so far:
-  X = 'a' + 2 * scsibus + target
-where target only may have the values 0 or 1.
-
-In this mode, option -scanbus will list only SCSI devices unless option
-dev=ATA or dev=ATAPI are given, which will suppress SCSI devices and only
-show IDE drives (i.e. /dev/hdX without ide-scsi emulation).
-
-
-In mode  --old_pseudo_scsi_adr  there is a scsibus,target,lun representation
-which has nothing to do with SCSI and thus is not compatible to cdrecord.
-Each number triple corresponds either to a device file address or to a
-libburn drive number.
-Component "scsibus" indicates the translation method. Defined busses are:
-  0  target is the libburn drivenumber as listed with --devices
-  1  associated to device file /dev/sgN , target chooses N
-  2  associated to device file /dev/hdX , target 0='a', 1='b' ..., 25='z' 
-
-So "1,1,0" is /dev/sg1, "2,3,0" is /dev/hdd, "0,2,0" is libburn drive #2 at
-some unspecified device file. 
-This scheme shall help to keep cdrecord-style addresses stable and exchangeable
-between users without excluding drives with unexpected device addresses.
-The numbering on bus 0 is prone to arbitrary changes caused by changes in
-drive accessability.
-Further busses may emerge as libburn evolves. "prefix" and "lun" may get
-a meaning. To stay upward compatible, use addresses as printed by -scanbus.
-
-                  User Defined Device Address Translation
-
-Some programs or users have their own ideas about the address of their burner.
-K3b 0.10 for example derives cdrecord addresses by own examination of the
-devices and not by calling cdrecord -scanbus.
-Standard mode will hopefully be fully compatible with their ideas.
-
-Old frontends which do not know dev=ATA or dev=ATAPI and which do ask their
-"cdrecord" via -scanbus may be well served with option  --old_pseudo_scsi_adr .
-
-To direct any remaining stubborn callers to the appropriate drives, cdrskin
-allows to define device address aliases. Like
-  cdrskin dev_translation=+1,0,0+/dev/sg1 \
-          dev_translation=+ATA:1,0,0+/dev/sg1 \
-          dev_translation=-"cd+dvd"-0,1,0 \
-          ...
-Any of the addresses dev=1,0,0, dev=ATA:1,0,0, dev=cd+dvd will be mapped to
-/dev/sg1 resp. to 0,1,0.
-The first character after "dev_translation=" defines the character which
-separates the two parts of the translation pair. (Above: "+" and "-".)
-
-In K3b 0.10 it is possible to employ alternative writer programs by setting
-their full path (e.g. /usr/bin/cdrskin) in menu
-  Settings:Configure K3b...:Programs:Search Path 
-and to make them default in menu
-  Settings:Configure K3b...:Programs:Programs:
-A suitable setting for "cdrecord" in menu 
-  Settings:Configure K3b...:Programs:User Parameters
-would then probably be
-  -v dev_translation=+1,0,0+/dev/sg1
-You will learn from button "Show Debugging Output" after a failed burn run
-what cdrecord command was used with what address "dev=...". This address "..."
-will be the right one to replace "1,0,0" in above example.

+                          DVD+RW , DVD-RAM , BD-RE
+
+These random access media get treated as blank media regardless wether they
+hold data or not. Options -audio and -multi are not allowed. Only one track
+is allowed. -toc does not return information about the media content.
+Speed is counted in DVD units (i.e. 1x = 1,385,000 bytes/second) or BD units
+(1x = 4,495,625 bytes/second). Currently there is no difference between -sao
+and -tao. If ever, then -tao will be the mode which preserves the current
+behavior.
+
+BD-RE media need formatting before first use. cdrskin option "blank=as_needed"
+recognizes unformatted BD-RE and applies a lengthy formatting run.
+
+During write operations DVD-RAM and BD-RE automatically apply Defect
+Management. This usually slows them down to half nominal speed. If drive
+and media produce flawless results anyway, then one can try to reach full
+nominal speed by option "stream_recording=on".
+In this case bad blocks are not detected during write and not even previously
+known bad blocks are avoided. So you have to make your own readability tests
+and go back to half speed as soon as the first read errors show up.
+Instead of "on" one may also set a start address for stream recording.
+Like "stream_recording=100m". This will write slowly to the first 100 MB of
+the media and accelerate when writing to higher addresses.

+                            DVD-RW , DVD-R , DVD-R DL
+
+DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
+"Sequential Recording". DVD-R are always in sequential state. DVD-R DL are
+always sequential and incapable of multi-session.
+
+"Sequential" is the state of unused media and of media previously blanked
+or written by cdrecord. dvd+rw-format -blank can also achieve this state.
+The according cdrskin option is blank=deformat_sequential .
+If "Incremental Streaming" is available, then sequential media are capable
+of multi-session like CD-R[W]. (But not capable of -audio recording.)
+This means they need option -multi to stay appendable, need to be blanked
+to be writeable from start, return useable info with -toc and -msinfo,
+eventually perform appending automatically.
+Without Incremental Streaming offered by the drive, only write mode DAO is
+available with sequential DVD-R[W]. It only works with blank media, allows only
+one single track, no -multi, and demands a fixely predicted track size.
+(growisofs uses it with DVD-R[W] if option -dvd-compat is given.)
+ 
+Overwriteable DVD-RW behave much like DVD+RW. "Restricted" refers only to the
+granularity of random access and block size which have always to be aligned to
+full 32 kB. Sequential DVD-RW are converted into overwriteable DVD-RW by
+  cdrskin dev=... -v blank=format_overwrite
+(Command  dvd+rw-format -force  can achieve Restricted Overwrite, too.)
+
+Formatting or first use of freshly formatted DVD-RW can produce unusual noises
+from the drive and last several minutes. Depending on mutual compatibility of
+drive and media, formatting can yield unusable media. It seems that those die
+too on blanking by cdrecord, dvd+rw-format or cdrskin. Perils of DVD-RW.
+
+There are three DVD-RW formatting variants with cdrskin currently:
+
+blank=format_overwrite  uses "DVD-RW Quick" formatting (MMC-type 15h)
+and writes a first session of 128 MiB. This leads to media which are expandable
+and random addressable by cdrskin.
+
+blank=format_overwrite_quickest  uses "DVD-RW Quick" formatting (type 15h) too,
+but leaves the media in "intermediate" state. In the first session of writing
+one may only write sequentially to such a DVD. After that, it gets random
+addressable by cdrskin. DVD-ROM drives might show ill behavior with them.
+
+blank=format_overwrite_full  uses preferrably "Full Format" (type 00h).
+This formatting lasts as long as writing a full DVD. It includes writing of
+lead-out which is said to be good for DVD ROM compatibility. 
+
+De-formatting options are available to make overwriteable DVD-RW sequential:
+
+blank=deformat_sequential  performs thorough blanking of all states of DVD-RW.
+blank=all and blank=fast perform the same thorough blanking, but refuse to do
+this with overwriteable DVD-RW, thus preserving their formatting. The specs
+allow minimal blanking but the resulting media on my drives offer no 
+Incremental Streaming afterwards. So blank=fast will do full blanking. 
+
+blank=deformat_sequential_quickest   is faster but might yield DAO-only media.
+
+
+                           DVD+R , DVD+R DL , BD-R
+
+From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
+into an own session, though.
+
+DVD+R DL appear as extra large DVD+R. cdrskin does not allow to set the address
+of the layer break where a reading drive might show some delay while switching
+between both media layers.
+
+BD-R are sold unformatted blank. If used without initial formatting then the
+drive is supposed to format them to maximum payload size with no Defect
+Management (see also above with BD-RE).
+If Defect Management is desired then BD-R need to be formatted before the
+first attempt to write a session to them.
+blank=format_if_needed    will detect the situation and eventually apply
+                          default sized Defect Management formatting.
+blank=format_defectmgt_*  will apply non-default parameters to formatting.
+
+
+                              Emulated Drives

+cdrskin can use filesystem objects as emulated drives. Regular files or block
+devices appear similar to DVD-RAM. Other file types resemble blank DVD-R.
+Necessary precondition is option --allow_emulated_drives which is not accepted
+if cdrskin took another user identity because of the setuid bit of its access
+permissions.
+Addresses of emulated drives begin with prefix "stdio:". E.g.
+  dev=stdio:/tmp/my_pseudo_drive
+
+For safety reasons the superuser is only allowed to use /dev/null as emulated
+drive. See man page section FILES for a way to lift that ban.
+
+
+------------------------------------------------------------------------------
+
                        Special compilation variations

+All following options of ./configure and cdrskin/compile_cdrskin.sh are
+combinable. After runs of ./configure do as next:
+    make clean ; make
+
+In some situations Linux may deliver a better write performance to drives if
+the track input is read with O_DIRECT (see man 2 open). The API call
+burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
+can be told to use this peculiar read mode by:
+    --enable-track-src-odirect
+
+But often cdrskin option dvd_obs=64k will yield even better performance in
+such a situation. 64k can be made default at compile time by 
+    cdrskin/compile_cdrskin.sh -dvd_obs_64k
+It can also be enabled at configure time by
+    ./configure ... --enable-dvd-obs-64k ...
+
+Alternatively the transport of SCSI commands can be done via libcdio-0.83.
+You may install it and re-run libburn's ./configure with option
+    --enable-libcdio
+
 You may get a (super fat) statically linked binary by :
    cdrskin/compile_cdrskin.sh -static
 if your system supports static linking, at all. This will not help with kernels

+
+                  System Dependend Drive Permission Examples
+
+Accessing the optical drives requires privileges which usually are granted
+only to the superuser. 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:
+  cdrskin --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 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 cdrskin by
+  pfexec cdrskin ...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 cdrskin can then be aquired 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/cdrskin: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.

+By Mario Danic <mario.danic@gmail.com> and Thomas Schmitt <scdbackup@gmx.net>
+Copyright (C) 2006-2011 Mario Danic, Thomas Schmitt

-We, the copyright holders, agree on the interpretation that
-dynamical linking of our libraries constitutes "use of" and
-not "derivation from" our work in the sense of GPL, provided
-those libraries are compiled from our unaltered code.
+libburnia-project.org is inspired by and in other components still containing
+parts of

+Copyright (C) 2002-2006  Derek Foreman and Ben Jansens
+See toplevel README for an overview of the current copyright situation in
+libburnia-project.org.

-Thus you may link our libraries dynamically with applications
-which are not under GPL. You may distribute our libraries and
-application tools in binary form, if you fulfill the usual
-condition of GPL to offer a copy of the source code -altered
-or unaltered- under GPL.

-We ask you politely to use our work in open source spirit
-and with the due reference to the entire open source community.
-
-If there should really arise the case where above clarification
-does not suffice to fulfill a clear and neat request in open source
-spirit that would otherwise be declined for mere formal reasons,
-only in that case we will duely consider to issue a special license
-covering only that special case.
-It is the open source idea of responsible freedom which will be
-decisive and you will have to prove that you exhausted all own
-means to qualify for GPL.
-
-For now we are firmly committed to maintain one single license: GPL.

-<DT>The goal is to provide some of cdrecord's options in a compatible way.
-This has been achieved quite sufficiently for the needs of backup tool
-<A HREF="http://scdbackup.sourceforge.net/main_eng.html">scdbackup</A>
-and for data CD projects of <A HREF="http://www.k3b.org">K3b</A> 
-(see <A HREF="#examples">examples</A>).
-Suitability for audio CD frontends has been improved much and is now being
-evaluated.<BR>
-Further enhancements depend on people who can describe and discuss their
-wishes as well as on the development of libburn.</DT>
+<DT>The most common options of cdrecord for data and audio on CD media
+are provided in a compatible way.<BR>
+On all DVD media, cdrskin is able to perform any recording job
+which is possible with cdrecord.
+Other than with cdrecord, option -multi is supported with many DVD types and
+BD-R. Write mode -tao works with anything but quickly blanked DVD-RW and
+DVD-R DL, which both support no -multi.

-cdrskin -scanbus or --devices hangs for quite a while if there is 
-a CD drive which does not work properly (e.g. because it has individual
-problems with DMA). 
-So if the superuser gets no result with cdrskin --devices then one should
-disable DMA with the problematic CD drives
-(like: <KBD>hdparm -d0 /dev/hdd</KBD> )
-and try again.<BR>
-In severe cases it might be necessary to guess the device name /dev/sgN resp.
-/dev/hdX of the non-ill burner if it cannot be found otherwise among its
-ill peers. Alternatively one can guess the address of the ill device, remove
-rw-permissions and retry the bus scan as non-superuser.

+blank=as_needed applies the suitable blanking or formatting to make
+any supported type of media ready for writing from scratch.
+If this is not possible, e.g. because the media is written and not
+re-usable, then the program run fails.
+
+Option blank= offers several specialized blanking and formatting types,
+which one may use for particular purposes on DVD-RW, DVD-RAM and BD-RE.
+(See also below: blank=format_overwrite)
+The drive offers a list of possible formats by cdrskin option --list_formats.
+One should aquire MMC background information before making use of them.
+
+--------------------------------------------------------------------------
+
+cdrskin does not only read from and write to optical drives which comply
+to the MMC standard but also does the same with regular files or block
+devices other than optical drives.
+
+Because the power to alter a disk file might be a bad surprise for a
+traditional user of cdrecord, it is necessary to give option
+--allow_emulated_drives before an emulated drive may be addressed.
+Eventually one of the startup files would be a good place for it.
+See man page, section FILES.
+
+The addresses of emulated drives begin with the prefix "stdio:".
+{{{
+dev=stdio:/tmp/pseudo_drive
+dev=stdio:/dev/usbstick
+}}}
+
+Regular files and block devices behave much like DVD-RAM.
+  
+Other file types may be valid targets for write-only operations.
+This includes standard output, named pipes, character devices
+{{{

+dev=stdio:/tmp/named_pipe
+dev=stdio:/dev/ptyxy

+
+These files behave much like blank DVD-R.
+
+All files used as pseudo-drives have to offer rw-permission.
+
+
+--------------------------------------------------------------------------
+
+The DVD capabilities of cdrskin differ from those of cdrecord-ProDVD. cdrskin
+offers TAO-like multi-session with DVD-R[W], DVD+R[ DL] and TAO-like single
+session with overwriteable DVD media. It also offers DAO on DVD-R[W] which is
+probably the same as the traditional cdrecord-ProDVD write mode.
+
+Non-cdrecord blank mode blank=format_overwrite brings a DVD-RW
+disc from its initial profile "Sequential Recording" into profile state
+"Restricted Overwrite".
+{{{
+cdrskin dev=/dev/sr0 -v blank=format_overwrite

+
+DVD-RAM, DVD+RW, BD-RE and overwriteable DVD-RW appear to cdrskin as blank
+media which are capable of taking only a single track. This track may be
+positioned on a 32KiB aligned address, though.
+{{{
+cdrskin ... write_start_address=2412m ...
+}}}
+
+Non-cdrecord blank mode blank=deformat_sequential brings an overwriteable
+DVD-RW back into state "Sequential Recording" with the capability of doing
+multi-session, if the drive is capable of "Incremental Streaming"
+(MMC feature 21h).
+
+Used sequential DVD-RW media may be blanked by blank=fast or blank=all which
+normally both do full blanking. Thus sequential DVD-RW behave much like large
+CD-RW with possibly more than 99 tracks.
+  
+blank=deformat_sequential does minimal blanking of DVD-RW which usually yields
+media incapable of "Incremental Streaming".
+
+Option --prodvd_cli_compatible activates blank=fast and blank=all for
+overwriteable DVD-RW which normally ignore those two options. It also makes
+option -multi tolerable with media and write modes which are not suitable for
+multi-session. (The default behavior of cdrskin deems me to be preferrable.)
+
+Option --grow_overwriteable_iso gives cdrskin ISO pseudo-multi-session
+capabilities on DVD-RAM, DVD+RW, BD-RE similar to growisofs.
+Associated options blank=, -multi, -msinfo and -toc are available in this case.
+They either pretend a blank media (if there is no ISO 9660 image) or appendable
+media with a single session and track on it. blank= invalidates ISO images.
+
+
+--------------------------------------------------------------------------
+
+assert_write_lba=<lba> allows to ensure that the start block address which
+was used with the formatter program (e.g. mkisofs -C) matches the start block
+address which will be used by the upcoming burn.
+
+E.g. cdrskin aborts with an error message if 
+{{{

+is given but an appendable media is to be burned which would start at
+block 68432.
+
+
+An ISO-9660 file system image must be prepared according to a particular
+block address on media. If the prepared address and the real address on media
+do not match then the filesystem will not be mountable or may even cause system
+trouble.
+
+A sequential archive format like afio or star will not necessarily need such

+Advanced multi-session use cases:
+
+A special feature of dvd+rw-tools is growing of ISO-9660 filesystems on
+overwriteable media. This is not the same as multi-session writing of cdrskin
+with CD media, but retrieves additional information from the existing ISO
+image and finally manipulates the start sectors of this existing image.
+
+So, inspired by growisofs, cdrskin can offer DVD multi-session not only with
+sequential DVD-R[W] and with DVD+R [DL], but also with DVD-RAM, DVD+RW, BD-RE
+and even regular disk files or block devices other than CD/DVD writers.
+This is enabled by option --grow_overwriteable_iso.
+
+The libburnia project provides an integrated ISO-9660 multi-session tool
+named [wiki:Xorriso xorriso] which tries to go one step beyond
+growisofs. It uses  [wiki:Libburn libburn] , [wiki:Libisofs libisofs]
+and [wiki:Libisoburn libisoburn].

+Users of modern desktop Linux installations report misburns with CD/DVD
+recording due to concurrency problems.
+
+This text describes two locking protocols which have been developed by our
+best possible effort. But finally they rather serve as repelling example of
+what would be needed in user space to achieve an insufficient partial solution.
+
+Ted Ts'o was so friendly to help as critic with his own use cases. It turned
+out that we cannot imagine a way in user space how to cover reliably the needs
+of callers of libblkid and the needs of our burn programs.
+
+-------------------------------------------------------------------------------
+Content:
+
+The "Delicate Device Locking Protocol" shall demonstrate our sincere
+consideration of the problem.
+
+"What are the Stumble Stones ?" lists reasons why the effort finally failed.
+
+-----------------------------------------------------------------------------
+
+
+                      Delicate Device Locking Protocol
+               (a joint sub project of cdrkit and libburnia)
+                       (contact: scdbackup@gmx.net )
+
+Our projects provide programs which allow recording of data on CD or DVD.
+We encounter an increasing number of bug reports about spoiled burn runs and
+wasted media which obviously have one common cause: interference by other
+programs which access the drive's device files.
+There is some riddling about which gestures exactly are dangerous for
+ongoing recordings or can cause weirdly misformatted drive replies to MMC 
+commands. 
+We do know, nevertheless, that these effects do not occur if no other program
+accesses a device file of the drive while our programs use it. 
+
+DDLP shall help to avoid collisions between programs in the process of
+recording to a CD or DVD drive and other programs which access that drive.
+The protocol intends to provide advisory locking. So any good-willing program
+has to take some extra precautions to participate.
+
+If a program does not feel vulnerable to disturbance, then the precautions
+impose much less effort than if the program feels the need for protection.
+
+Two locking strategies are specified:
+DDLP-A operates on device files only. It is very Linux specific.
+DDLP-B adds proxy lock files, inspired by FHS /var/lock standard.
+
+
+                                  DDLP-A
+
+This protocol relies on the hardly documented feature open(O_EXCL | O_RDWR)
+with Linux device files and on POSIX compliant fcntl(F_SETLK).
+
+Other than the original meaning of O_EXCL with creating regular files, the
+effect on device files is mutual exclusion of access. I.e. if one
+filedescriptor is open on that combination of major-minor device number, then
+no other open(O_EXCL) will succeed. But open() without O_EXCL would succeed.
+So this is advisory and exclusive locking.
+With kernel 2.6 it seems to work on all device drivers which might get used
+to access a CD/DVD drive.
+
+The vulnerable programs shall not start their operation before they occupied a
+wide collection of drive representations.
+Non-vulnerable programs shall take care to detect the occupation of _one_ such
+representation.
+
+                          So for Friendly Programs
+
+A program which does not feel vulnerable to disturbance is urged to access
+CD/DVD drives by opening a file descriptor which will uphold the lock
+as long as it does not get closed. There are two alternative ways to achieve
+this.
+Very reliable is  
+
+  open( some_path , O_EXCL | ...)
+
+But O_EXCL imposes restrictions and interferences:
+- O_EXCL | O_RDONLY does not succeed with /dev/sg* !
+- O_EXCL cannot provide shared locks for programs which only want to lock
+  against burn programs but not against their own peers.
+- O_EXCL keeps from obtaining information by harmless activities.
+- O_EXCL already has a meaning with devices which are mounted as filesystems.
+  This priority meaning is more liberal than the one needed for CD/DV recording
+  protection.
+
+So it may be necessary to use a cautious open() without O_EXCL and to aquire
+a POSIX lock via fcntl(). "Cautious" means to add O_NDELAY to the flags of
+open(), because this is declared to avoid side effects within open().
+
+With this gesture it is important to use the paths expected by our burn
+programs: /dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z]
+because fcntl(F_SETLK) does not lock the device but only a device-inode.
+
+  std_path = one of the standard device files:
+               /dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z]
+             or a symbolic link pointing to one of them.
+  open( std_path , ... | O_NDELAY)
+  fcntl(F_SETLK) and close() on failure
+  ... eventually disable O_NDELAY by fcntl(F_SETFL) ...
+
+There is a pitfall mentioned in man 2 fcntl :
+ "locks are automatically released [...] if it closes any file descriptor
+  referring to a file on which locks are held. This is bad [...]"
+So you may have to re-lock after some temporary fd got closed.
+
+
+                            Vulnerable Programs
+
+For programs which do feel vulnerable, O_EXCL would suffice for the /dev/hd*
+device file family and their driver. But USB and SATA recorders appear with
+at least two different major-minor combinations simultaneously.
+One as /dev/sr* alias /dev/scd*, the other as /dev/sg*.
+The same is true for ide-scsi or recorders attached to SCSI controllers.
+
+So, in order to lock any access to the recorder, one has to open(O_EXCL)
+not only the device file that is intended for accessing the recorder but also
+a device file of any other major-minor representation of the recorder.
+This is done via the SCSI address parameter vector (Host,Channel,Id,Lun)
+and a search on standard device file paths /dev/sr* /dev/scd* /dev/sg*.
+In this text the alternative device representations are called "siblings".
+
+For finding them, it is necessary to apply open() to many device files which
+might be occupied by delicate operations. On the other hand it is very
+important to occupy all reasonable representations of the drive.
+So the reading of the (Host,Channel,Id,Lun) parameters demands an 
+open(O_RDONLY | O_NDELAY) _without_ fcntl() in order to find the outmost
+number of representations among the standard device files. Only ioctls
+SCSI_IOCTL_GET_IDLUN and SCSI_IOCTL_GET_BUS_NUMBER are applied.
+Hopefully this gesture is unable to cause harmful side effects on kernel 2.6.
+
+At least one file of each class sr, scd and sg should be found to regard
+the occupation as satisfying. Thus corresponding sr-scd-sg triplets should have
+matching ownerships and access permissions.
+One will have to help the sysadmins to find those triplets.
+
+A spicy detail is that sr and scd may be distinct device files for the same
+major-minor combination.  In this case fcntl() locks on both are needed
+but O_EXCL can only be applied to one of them.

+An open and free implementation ddlpa.[ch] is provided as
+  http://libburnia.pykix.org/browser/libburn/trunk/libburn/ddlpa.h?format=txt
+  http://libburnia.pykix.org/browser/libburn/trunk/libburn/ddlpa.c?format=txt
+The current version of this text is 
+  http://libburnia.pykix.org/browser/libburn/trunk/doc/ddlp.txt?format=txt
+
+Put ddlpa.h and ddlpa.c into the same directory and compile as test program by
+  cc -g -Wall -DDDLPA_C_STANDALONE -o ddlpa ddlpa.c
+
+Use it to occupy a drive's representations for a given number of seconds
+  ./ddlpa /dev/sr0 300
+
+It should do no harm to any of your running activities.
+If it does: Please, please alert us.
+
+Your own programs should not be able to circumvent the occupation if they
+obey above rules for Friendly Programs.
+Of course ./ddlpa should be unable to circumvent itself.
+
+A successfull occupation looks like
+  DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/scd0") = "/dev/sr0"
+  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sr0"
+  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/scd0"
+  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sg0"
+  DDLPA_DEBUG: ddlpa_occupy()        : '/dev/scd0'
+  DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/sg0'
+  DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/sr0'
+  ---------------------------------------------- Lock gained
+  ddlpa: opened           /dev/sr0
+  ddlpa: opened siblings: /dev/scd0 /dev/sg0
+  slept 1 seconds of 300
+
+Now an attempt via device file alias /dev/NEC must fail:
+  DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/NEC") = "/dev/sg0"
+  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sr0"
+  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/scd0"
+  DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sg0"
+  Cannot exclusively open '/dev/sg0'
+  Reason given    : Failed to open O_RDWR | O_NDELAY | O_EXCL : '/dev/sr0'
+  Error condition : 16 'Device or resource busy'
+
+With hdc, of course, things are trivial
+  DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/hdc") = "/dev/hdc"
+  DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/hdc'
+  ---------------------------------------------- Lock gained
+  ddlpa: opened           /dev/hdc
+  slept 1 seconds of 1
+
+
+Ted Ts'o provided program  open-cd-excl  which allows to explore open(2) on
+device files with combinations of read-write, O_EXCL, and fcntl().
+(This does not mean that Ted endorsed our project yet. He helps exploring.)
+
+Friendly in the sense of DDLP-A would be any run which uses at least one of
+the options -e (i.e. O_EXCL) or -f (i.e. F_SETLK, applied to a file
+descriptor which was obtained from a standard device file path).
+The code is available under GPL at
+  http://libburnia.pykix.org/browser/libburn/trunk/test/open-cd-excl.c?format=txt
+To be compiled by
+  cc -g -Wall -o open-cd-excl open-cd-excl.c
+
+Options:
+  -e : open O_EXCL
+  -f : aquire lock by fcntl(F_SETLK) after sucessful open
+  -i : do not wait in case of success but exit 0 immediately
+  -r : open O_RDONLY , with -f use F_RDLCK
+  -w : open O_RDWR   , with -f use F_WRLCK
+  plus the path of the devce file to open.
+
+Friendly Programs would use gestures like:
+  ./open-cd-excl -e -r /dev/sr0
+  ./open-cd-excl -e -w /dev/sg1
+  ./open-cd-excl -e -w /dev/black-drive
+  ./open-cd-excl -f -r /dev/sg1
+  ./open-cd-excl -e -f -w /dev/sr0
+
+Ignorant programs would use and cause potential trouble by:
+  ./open-cd-excl -r /dev/sr0
+  ./open-cd-excl -w /dev/sg1
+  ./open-cd-excl -f -w /dev/black-drive
+where "/dev/black-drive" is _not_ a symbolic link to
+any of /dev/sr* /dev/scd* /dev/sg* /dev/hd*, but has an own inode.
+
+Prone to failure without further reason is:
+  ./open-cd-excl -e -r /dev/sg1
+

+
+                                  DDLP-B
+
+This protocol relies on proxy lock files in some filesystem directory. It can
+be embedded into DDLP-A or it can be used be used standalone, outside DDLP-A.
+
+DDLP-A shall be kept by DDLP-B from trying to access any device file which
+might already be in use. There is a problematic gesture in DDLP-A when SCSI
+address parameters are to be retrieved. For now this gesture seems to be
+harmless. But one never knows.
+Vice versa DDLP-B may get from DDLP-A the service to search for SCSI device
+file siblings. So they are best as a couple.
+
+But they are not perfect. Not even as couple. fcntl() locking is flawed.
+ 
+
+There is a proxy file locking protocol described in FHS:
+  http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES
+
+But it has shortcommings (see below). Decisive obstacle for its usage are the
+possibility for stale locks and the lack of shared locks.
+
+DDLP-B rather defines a "path prefix" which is advised to be
+  /tmp/ddlpb-lock-
+This prefix will get appended "device specific suffixes" and then form the path
+of a "lockfile".
+Not the existence of a lockfile but its occupation by an fcntl(F_SETLK) will
+constitute a lock. Lockfiles may get prepared by the sysadmin in directories
+where normal users are not allowed to create new files. Their rw-permissions
+then act as additional access restriction to the device files.
+The use of fcntl(F_SETLK) will prevent any stale locks after the process ended.
+It will also allow to obtain shared locks as well as exclusive locks.
+
+There are two classes of device specific suffixes:
+
+- Device file path suffix. Absolute paths only. "/" gets replaced by "_-". 
+  Eventual "_-" in path gets replaced by "_-_-". The leading group of "_-"
+  is always interpreted as a group of "/", though.  E.g.:
+    /dev/sr0           <-> "_-dev_-sr0"
+    /mydevs/burner/nec <-> "_-mydevs_-burners_-nec"
+    /dev/rare_-name    <-> "_-dev_-rare_-_-name"
+    ///strange/dev/x   <-> "_-_-_-strange_-dev_-x"
+
+- st_rdev suffix. A hex representation of struct stat.st_rdev. Capital letters.
+  The number of characters is pare with at most one leading 0. I.e. bytewise
+  printf("%2.2X") beginning with the highest order byte that is not zero.
+  E.g. : "0B01", "2200", "01000000000004001"
+
+If a lockfile does not exist and cannot be created then this shall not keep
+a program from working on a device. But if a lockfile exists and if permissions
+or locking state do not allow to obtain a lock of the appropirate type, then
+this shall prevent any opening of device file in question resp. shall cause
+immediate close(2) of an already opened device file.
+
+The vulnerable programs shall not start their operation before they locked a
+wide collection of drive representations.
+
+Non-vulnerable programs shall take care to lock the suffix resulting from the
+path they will be using and the suffix from the st_rdev from that path.
+The latter is to be obtained by call stat(2).
+
+Locks get upheld as long as their file descriptor is not closed or no other
+incident as described in man 2 fcntl releases the lock.
+
+So with shared locks there are no imandatory further activities after they
+have been obtained.
+
+In case of exclusive locks, the file has to have been opened for writing and
+must be truncated to 0 bytes length immediately after obtaining the lock.
+When releasing an exclusive lock it is a nice gesture to
+already do this truncation.
+Then a /var/lock/ compatible first line has to be written.
+E.g. by:  printf("%10u\n",(unsigned) getpid()) yielding "      1230\n".
+
+Any further lines are optional. They shall have the form Name=Value and must
+be printable cleartext. If such further lines exist, then the last one must
+have the name "endmark".
+Defined Names are:
+  hostid   =hostname of the machine where the process number of line 1 is valid
+  start    =start time of lock in seconds since 1970. E.g: 1177147634.592410
+  program  =self chosen name of the program which obtained the lock
+  argv0    =argv[0] of that program
+  mainpath =device file path which will be used for operations by that program
+  path     =device file path which lead to the lock
+  st_rdev  =st_rdev suffix which is associated with path
+  scsi_hcil=eventual SCSI parameters Host,Channel,Id,Lun
+  scsi_bus =eventual SCSI parameter Bus
+  endmark  =declares the info as complete.
+Any undefined name or a line without "=" shall be handled as comment.
+"=" in the value is allowed. Any line beginning with an "=" character is an
+extension of the previous value.
+
+If programs encounter an exclusive lock, they are invited to read the content
+of the lockfile anyway. But they should be aware that the info might be in the
+progress of emerging. There is a race condition possible in the short time
+between obtaining the exclusive lock and erasing the file content.
+If it is not crucial to obtain most accurate info then one may take the newline
+of the first line as indicator of a valid process number and the "endmark"
+name as indicator that the preceding lines are valid.
+Very cautious readers should obtain the info twice with a decent waiting period
+inbetween. Only if both results are identical they should be considered valid.
+
+
+There is no implementation of DDLP-B yet.
+
+
+ 
+----------------------------------------------------------------------------
+What are the Stumble Stones ?
+----------------------------------------------------------------------------
+
+Any of the considered locking mechanisms has decisive shortcommings
+which keeps it from being the solution to all known legitimate use cases.
+
+The attempt has failed to compose a waterproof locking mechanism from means of
+POSIX, FHS and from hardly documented Linux open(O_EXCL) on device files.
+The resulting mechanisms would need about 1000 lines of code and still do
+not close all gaps resp. cover the well motivated use cases.
+This attempt you see above: DDLP-A and DDLP-B.
+
+
+Summary of the reasons why the established locking mechanisms do not suffice:
+
+None of the mechanisms can take care of the double device driver identity
+sr versus sg. To deduce the one device file from the other involves the need
+to open many other (possibly unrelated) device files with the risk to disturb
+them.
+This hard to solve problem is aggravated by the following facts.
+
+Shortcommings of Linux specific open(O_EXCL) :
+
+- O_EXCL | O_RDONLY does not succeed with /dev/sg*
+- O_EXCL cannot provide shared locks for programs which only want to lock
+  against burn programs but not against their own peers.
+- O_EXCL keeps from obtaining information by harmless activities.
+- O_EXCL already has a meaning with devices which are mounted as filesystems.
+  This priority meaning is more liberal than the one needed for CD/DV recording
+  protection.
+
+Shortcommings of POSIX fcntl(F_SETLK) :
+
+- fcntl() demands an open file descriptor. open(2) might have side effects.
+- fcntl() locks can be released inadvertedly by submodules which just open and
+  close the same file (inode ?) without refering to fcntl locks in any way.
+  See man 2 fcntl "This is bad:". 
+  Stacking of software modules is a widely used design pattern. But fcntl()
+  cannot cope with that.
+
+Shortcommings of FHS /var/lock/ :
+
+- Stale locks are possible.
+- It is necessary to create a file (using the _old_ meaning of O_EXCL flag ?)
+  but /var/lock/ might not be available early during system start and it often
+  has restrictive permission settings.
+- There is no way to indicate a difference between exclusive and shared locks.
+- The FHS prescription relies entirely on the basename of the device file path.

+
+   This code module implements the production of RSPC parity bytes (P- and Q-
+   parity) and the scrambling of raw CD-ROM sectors as specified in ECMA-130:
+     http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-130.pdf
+
+   The following statements about Galois Fields have been learned mostly from
+     http://www.cs.utk.edu/~plank/plank/papers/CS-96-332.pdf
+   by James S. Plank after an e-mail exchange with Norbert Preining.
+
+   The output has been compared with the output of the old code of libburn
+   which was labeled "borrowed HEAVILY from cdrdao" and claimed by Joerg
+   Schilling to stem from code by Heiko Eissfeldt.
+
+   -------------------------------------------------------------------------
+   Note: In this text, "^" denotes exponentiation and not the binary exor
+         operation. Confusingly in the C code "^" is said exor.
+   Note: This is not C1, C2 which is rather mentioned in ECMA-130 Annex C and
+         always performed inside the drive.
+   -------------------------------------------------------------------------
+
+
+                            RSPC resp. P- and Q-Parity
+
+   ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and
+   Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating
+   polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02).
+   Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words
+   as 24 rows and 43 columns. Then this matrix is split into a LSB matrix
+   and a MSB matrix of the same layout. Parity bytes are to be computed
+   from these 8-bit values.
+   2 P-bytes cover each column of 24 bytes. They get appended to the matrix
+   as rows 24 and 25.
+   2 Q-bytes cover each the 26 diagonals of the extended matrix.
+
+   Both parity byte pairs have to be computed so that extended rows or
+   diagonals match this linear equation:
+      H x V = (0,0)
+   H is a 2-row matrix of size n matching the length of the V ectors
+     [   1        1     ...   1   1 ]
+     [ x^(n-1)  x^(n-2)      x^1  1 ]
+   Vp represents a P-row. It is a byte vector consisting of row bytes at
+   position 0 to 23 and the two parity bytes which shall be determined
+   at position 24 and 25. So Hp has 26 columns.
+   Vq represents a Q-diagonal. It is a byte vector consisting of diagonal
+   bytes at position 0 to 42 and the two parity bytes at position 43 and 44.
+   So Hq has 45 columns. The Q-diagonals cover P-parity bytes.
+
+   By applying some high school algebra one gets the parity bytes b0, b1 of
+   vector V = (n_payload_bytes, b0 , b1) as
+
+     b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes )
+          / (H[n+1] - H[n])
+     b1 = - SUM(n_payload_bytes) - b0
+
+   H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1)
+   The result has to be computed by Galois field arithmetics. See below.
+
+   The P-parity bytes of each column get reunited as LSB and MSB of two words.
+   word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117.
+   The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118
+   to 1143, word0 to 1144 to 1169.
+   >>> I do not read this swap of word1 and word0 from ECMA-130 Annex A.
+   >>> But the new output matches the old output only if it is done that way.
+   >>> See correctness reservation below.
+
+   Algebra on Galois fields is the same as on Rational Numbers.
+   But arithmetics is defined by operations on polynomials rather than the
+   usual integer arithmetics on binary numbers.
+   Addition and subtraction are identical with the binary exor operator.
+   Multiplication and division would demand polynomial division, e.g. by the
+   euclidian algorithm. The computing path over logarithms and powers follows
+   algebra and allows to reduce the arithmetic task to table lookups, additions
+   modulo 255, and exor operations. Note that the logarithms are natural
+   numbers, not polynomials. They get added or subtracted by the usual addition
+   (not by exor) and their polynomial power depends on their value modulo 255.
+
+   Needed are a logarithm table and a power table (or inverse logarithm table)
+   for Galois Field GF(2^8) which will serve to perform the peculiar
+   multiplication and division operation of Galois fields.
+
+   The power table is simply an enumeration of x^n accorting to
+   GF-multiplication. It also serves as second line of matrix H for the parity
+   equations:
+     Hp[i] = gfpow[25-i] , i out of {0,..,25}
+     Hq[i] = gfpow[44-i] , i out of {0,..,44}
+
+   The logarithm table is the inverse permutation of the power table.
+
+   Some simplifications apply to the implementation:
+   In the world of Galois fields there is no difference between - and +.
+   The term (H[n+1] - H[n]) is constant: 3.
+
+   -------------------------------------------------------------------------
+
+
+                                 Scrambling
+
+   ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector
+   with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and
+   a 15-bit register.
+   It shows a diagram of a Feedback Shift Register with 16 bit boxes, though.
+ 
+   Comparing this with explanations in 
+     http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm
+   one can recognize the diagram as a Fibonacci Implementation. But there seems
+   really to be one bit box too many.
+
+   The difference of both lengths is expressed in function next_bit() by
+   the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits.
+   Comparing the output of both alternatives with the old scrambler output
+   lets 15 bit win for now.
+
+   So the prescription is to start with 15 bit value 1, to use the lowest bit
+   as output, to shift the bits down by one, to exor the output bit with the
+   next lowest bit, and to put that exor result into bit 14 of the register.
+
+   -------------------------------------------------------------------------
+
+
+                             Correctness Reservation
+
+   In both cases, parity and scrambling, the goal for now is to replicate the
+   output of the dismissed old lec.c by output which is based on published
+   specs and own implementation code. Whether they comply to ECMA-130 is a
+   different question which can only be answered by real test cases for
+   raw CD recording.
+
+   Of course this implementation will be corrected so that it really complies
+   to ECMA-130 as soon as evidence emerges that it does not yet.

+
+  Owner of libdax_msgs is libburn. A fully compatible variant named libiso_msgs
+  is owned by libisofs and can get generated by a script of the libburn
+  project: libburn/libdax_msgs_to_xyz_msgs.sh .
+
+  Reason: One cannot link two owners of the same variant together because
+  both would offer the same functions to the linker. For that situation one
+  has to create a compatible variant as it is done for libisofs.
+
+  Compatible variants may get plugged together by call combinations like
+    burn_set_messenger(iso_get_messenger());
+  A new variant would demand a _set_messenger() function if it has to work
+  with libisofs. If only libburn is planned as link partner then a simple
+  _get_messenger() does suffice.
+  Take care to shutdown libburn before its provider of the *_msgs object
+  gets shut down.

+This is the main operating system dependent SCSI part of libburn. It implements
+the transport level aspects of SCSI control and command i/o.
+
+Present implementation: GNU libcdio , for X/Open compliant operating systems
+
+
+PORTING:
+
+Porting libburn typically will consist of adding a new operating system case
+to the following switcher files:
+  os.h    Operating system specific libburn definitions and declarations.
+  sg.c    Operating system dependent transport level modules.
+and of deriving the following system specific files from existing examples:
+  os-*.h  Included by os.h. You will need some general system knowledge
+          about signals and knowledge about the storage object needs of your
+          transport level module sg-*.c.
+
+  sg-*.c  This source module. You will need special system knowledge about
+          how to detect all potentially available drives, how to open them,
+          eventually how to exclusively reserve them, how to perform
+          SCSI transactions, how to inquire the (pseudo-)SCSI driver.
+          You will not need to care about CD burning, MMC or other high-level
+          SCSI aspects.
+
+Said sg-*.c operations are defined by a public function interface, which has
+to be implemented in a way that provides libburn with the desired services:

+                        return only a preliminary id.
+
+sg_initialize()         performs global initialization of the SCSI transport
+                        adapter and eventually needed operating system
+                        facilities. Checks for compatibility of supporting
+                        software components.

+sg_drive_is_open()      tells wether libburn has the given drive in use.
+
+sg_grab()               opens the drive for SCSI commands and ensures
+                        undisturbed access.
+
+sg_release()            closes a drive opened by sg_grab()
+
+sg_issue_command()      sends a SCSI command to the drive, receives reply,
+                        and evaluates wether the command succeeded or shall
+                        be retried or finally failed.
+
+sg_obtain_scsi_adr()    tries to obtain SCSI address parameters.

+
+This is the main operating system dependent SCSI part of libburn. It implements
+the transport level aspects of SCSI control and command i/o.
+
+Present implementation: Solaris uscsi, e.g. for SunOS 5.11
+
+
+PORTING:
+
+Porting libburn typically will consist of adding a new operating system case
+to the following switcher files:
+  os.h    Operating system specific libburn definitions and declarations.
+  sg.c    Operating system dependent transport level modules.
+and of deriving the following system specific files from existing examples:
+  os-*.h  Included by os.h. You will need some general system knowledge
+          about signals and knowledge about the storage object needs of your
+          transport level module sg-*.c.
+
+  sg-*.c  This source module. You will need special system knowledge about
+          how to detect all potentially available drives, how to open them,
+          eventually how to exclusively reserve them, how to perform
+          SCSI transactions, how to inquire the (pseudo-)SCSI driver.
+          You will not need to care about CD burning, MMC or other high-level
+          SCSI aspects.
+
+Said sg-*.c operations are defined by a public function interface, which has
+to be implemented in a way that provides libburn with the desired services:
+
+sg_id_string()          returns an id string of the SCSI transport adapter.
+                        It may be called before initialization but then may
+                        return only a preliminary id.
+
+sg_initialize()         performs global initialization of the SCSI transport
+                        adapter and eventually needed operating system
+                        facilities. Checks for compatibility of supporting
+                        software components.
+
+sg_shutdown()           performs global finalizations and releases golbally
+                        aquired resources.
+
+sg_give_next_adr()      iterates over the set of potentially useful drive 
+                        address strings.
+
+scsi_enumerate_drives() brings all available, not-whitelist-banned, and
+                        accessible drives into libburn's list of drives.
+
+sg_dispose_drive()      finalizes adapter specifics of struct burn_drive
+                        on destruction. Releases resources which were aquired
+                        underneath scsi_enumerate_drives().
+ 
+sg_drive_is_open()      tells wether libburn has the given drive in use.
+
+sg_grab()               opens the drive for SCSI commands and ensures
+                        undisturbed access.
+
+sg_release()            closes a drive opened by sg_grab()
+
+sg_issue_command()      sends a SCSI command to the drive, receives reply,
+                        and evaluates wether the command succeeded or shall
+                        be retried or finally failed.
+
+sg_obtain_scsi_adr()    tries to obtain SCSI address parameters.
+
+
+burn_os_is_2k_seekrw()  tells whether the given path leads to a file object
+                        that can be used in 2 kB granularity by lseek(2),
+                        read(2), and possibly write(2) if not read-only..
+                        E.g. a USB stick or a hard disk.
+
+burn_os_stdio_capacity()  estimates the emulated media space of stdio-drives.
+
+burn_os_open_track_src()  opens a disk file in a way that allows best
+                        throughput with file reading and/or SCSI write command
+                        transmission.
+
+burn_os_alloc_buffer()  allocates a memory area that is suitable for file
+                        descriptors issued by burn_os_open_track_src().
+                        The buffer size may be rounded up for alignment
+                        reasons.
+
+burn_os_free_buffer()   delete a buffer obtained by burn_os_alloc_buffer().
+
+Porting hints are marked by the text "PORTING:".
