+For now this means CD media, all DVD media except DVD-R DL, 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 Linux with kernels >= 2.4 and on FreeBSD versions 
+with ATAPI/CAM support enabled in the kernel, see atapicam(4).
+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.

 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

            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.

-           ISO 9660 disk image. This may then be brought to media via libburn.

+- 9th Dec 2008 Our project received a donation from Thomas Weber.
+
+- 2nd Jan 2009 libburn-0.6.0 allows to format BD-R and to write to either
+  formatted or unformatted BD-R.
+
+- 6th Jan 2009 libisoburn-0.3.2. xorriso can produce and execute commands for
+  mounting older sessions from all kinds of media. Pseudo-drives outside the
+  /dev/ tree can be addressed without prefix "stdio:". 
+
+- 20th Feb 2009 libburn-0.6.2 source release now compiles out of the box
+  on FreeBSD.
+
+- 28 Feb 2009 libisofs-0.6.14 can record ACLs and Extended Attributes xattr
+  in its ISO images. 
+
+- 01 Mar 2009 libisoburn-0.3.4. xorriso makes use of the ACL and xattr
+  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
+  filter processes allow arbitrary data conversions like encryption.
+
+- 19 Apr 2009 libisoburn-0.3.8 makes use of the new libisofs capability to
+  perform content filtering of data files.
+
+- 08 May 2009 libburn-0.6.6 fixes a bug with aborting on broken output pipe
+  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-0.7.2.pl01 fixes the release tarball which was lacking
+  the files of the generic system adapter for X/Open.

-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

-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

-
-                             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.

+BD-RE media need formatting before first use. cdrskin option "blank=as_needed"

-Program growisofs can append to an ISO filesystem on DVD+RW by additionally

+During write operations DVD-RAM and BD-RE automatically apply Defect

-Suitability for audio CD frontends has been improved much and is now being
-evaluated.<BR>
-DVD are written in a pseudo -tao mode which is very different from the
-write mode used by cdrecord(-ProDVD).<BR>
-Further enhancements depend on people who can describe and discuss their

+<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 except DVD-R DL, 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.

-In severe cases it might be necessary to guess the device name /dev/sgN resp.

 '''cdrskin is the cdrecord compatibility middleware of libburn.'''
 
 Its paragon, 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. Currently it does CD-R and CD-RW this way.

-The current development version handles sequential DVD-R[W] like CD-R[W]

 cdrskin does not contain any bytes copied from cdrecord's sources.
 Many bytes have been copied from the message output of cdrecord

 A special feature of dvd+rw-tools is growing of ISO-9660 filesystems on

 with CD media, but retrieves additional information from the existing ISO
 image and finally manipulates the start sectors of this existing image.

-dnl if MAJOR or MINOR version changes, be sure to change AC_INIT above to match
+dnl Regrettably the meaning of the various version types was misunderstood

 dnl

+dnl
+dnl Meanwhile the following schemes are maintained in parallel:
+dnl
+dnl BURN_MAJOR_VERSION , BURN_MINOR_VERSION , BURN_MICRO_VERSION 
+dnl    are three small non-negative integers which describe the evolution
+dnl    steps of the library.
+dnl    Older applications are able to use younger libraries over
+dnl    quite a long range of such steps. Some day, nevertheless,
+dnl    compatibility might get terminated, after due notice.
+dnl
+dnl SONAME (libburn.so.4)
+dnl    is a small positive integer which marks a family of compatible
+dnl    evolution steps. Libraries with a particular SONAME allow a binary
+dnl    with the same SONAME to start up. Any further compatibility check is to
+dnl    be done by own runtime means. Especially  *_version() calls in the API
+dnl    which return BURN_MAJOR_VERSION, BURN_MINOR_VERSION, BURN_MICRO_VERSION.
+dnl    See below.
+dnl
+dnl CURRENT, AGE, REVISION
+dnl    are three integers used by libtool. CURRENT is positive, the others
+dnl    non-negative. The use at runtime is not known yet. But libtool computes
+dnl    at build time  SONAME = CURRENT - AGE.
+dnl    So this is a superspace of the SONAME version space. To avoid
+dnl    ill SONAME, the value of  CURRENT must be larger than AGE.
+dnl    See also http://www.gnu.org/software/libtool/manual.html#Interfaces
+dnl
+dnl On Linux the name of the dynamic library will be
+dnl    libburn.so.$SONAME.$AGE.$REV
+dnl In the terminology of this file:
+dnl    CURRENT = LT_CURRENT
+dnl    AGE     = LT_AGE
+dnl    REVISION= LT_REVISION
+dnl
+dnl Beginning with libburn-0.4.1 a rectified counting was introduced as
+dnl    CURRENT=10, REVISION=1, AGE=6
+dnl This rectification declared that version to be binary compatible up
+dnl from libburn-0.3.4.
+dnl Real compatibility was given since libburn-0.3.2.
+dnl Beware of libburn-0.2.6 which had SONAME=6 and is not binary compatible.
+dnl Applications for libburn-0.2 to libburn-0.3.1 need recompilation but no
+dnl source code changes.
+dnl
+dnl Neatly versioned stable releases meanwhile:
+dnl    0.4.2 = libburn.so.4.7.0
+dnl    0.4.4 = libburn.so.4.9.0
+dnl    0.4.6 = libburn.so.4.11.0
+dnl    0.4.8 = libburn.so.4.13.0
+dnl    0.5.0 = libburn.so.4.15.0
+dnl    0.5.2 = libburn.so.4.17.0
+dnl    0.5.4 = libburn.so.4.19.0
+dnl    0.5.6 = libburn.so.4.21.0
+dnl    0.5.8 = libburn.so.4.23.0
+dnl    0.6.0 = libburn.so.4.25.0
+dnl    0.6.2 = libburn.so.4.27.0

+dnl    0.7.2 = libburn.so.4.37.0
+dnl    0.7.4 = libburn.so.4.39.0
+dnl
+dnl So LT_CURRENT, LT_REVISION and LT_AGE get set directly here.
+dnl SONAME of the emerging library is  LT_CURRENT - LT_AGE.
+dnl The linker will do no finer checks. Especially no age range check for
+dnl the application binary. If SONAME matches, then the couple starts.
+dnl 
+dnl Therefore at run time info is provided by libburn function burn_version().
+dnl It returns the major, minor and micro revision of the library.
+dnl Before using any API feature, a program should check for age.
+dnl
+dnl The variables BURN_*_VERSION are mere copies for informing libtool.
+dnl The true values which get issued and should be compared are macros
+dnl defined in libburn/libburn.h .
+dnl
+dnl Normally one can allow a program to run with a library which passed the
+dnl linker SONAME test and which is not older than the library it was
+dnl developed for. Library2 is younger than library1 if:

+DVD-RAM and BD-RE formatting :
+
+Although DVD-RAM usually are sold formatted, there may still arise the wish
+to adjust formatting.
+BD-RE are sold unformatted and need to be formatted prior to usage.
+
+Two format types are relevant for DVD-RAM : 00h and 01h.
+00h offers the default size format and usually a maximum payload size format.
+Even with that maximum size payload there is hardware defect management.
+(mmc5r03c.pdf 6.5.4.2.1.2)
+01h allows to convert payload capacity into spare blocks for defect
+managment. There is no way to increase payload capacity by format 01h.
+(mmc5r03c.pdf 6.5.4.2.2.1)
+
+With BD-RE there are three format types : 00h, 30h and 31h.
+00h offers the default size format. This may be the only fast formatting
+mode that is offered by the drive.
+Feature 0023h tells whether format 31h and certain 30h subtypes are available.
+(mmc5r03c.pdf 5.3.13)
+30h offers several sizes with defect management. Usually there are three
+sizes given: #1: default size, #2: maximum spare area, #3: minimal spare.
+One may demand any spare size between maximum and minimum. There may be quick
+certification and full certification. See feature 0023h.
+31h offers a single size and disables defect management. This has the side
+effect to speed up writing to nominal speed.
+(mmc5r03c.pdf 6.5.4.2.15, 6.24.3.3, Table 472)
+
+Only format sizes from the list of format descriptors are permissible
+for DVD-RAM. The format list can be obtained by 23h READ FORMAT CAPACITIES.
+It also includes a description of the current formatting state.
+(mmc5r03c.pdf 6.24, 6.24.3.2, 6.24.3.3)
+
+Formatting is done by command 04h FORMAT UNIT. Its data payload consists
+of a Format List Header and a Format Descriptor. It is advisable to set
+the Immed bit and the FOV bit in header byte number 1. The descriptor should
+be a copy of a descriptor from 23h READ FORMAT CAPACITIES.
+(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
+With nearly all formats Sub-type should be set to 0. But with BD-RE formats
+30h and 31h the Sub-type selects the certification mode.
+Usable with 30h seem 10b Full Certification and 11b Quick Certification.
+Usable with 31h seem also 00b Quick Reformat and 01b No Certification.
+(mmc5r03c.pdf 6.5.4.2.15.1)
+
+Other format types have their certification intensity controlled by
+a pair of bits: CmpList and DCRT.
+CmpList resides in CDB byte 1 as bit 3. DCRT resides in the payload byte 1
+as bit 5. Both together should request a quick size change without lengthy
+certification but maintaining the list of known defects.
+(mmc5r03c.pdf 6.5, table 249, 6.5.3.2)
+With DVD-RAM on my PHILIPS SPD3300L drive they prevent any format size
+change though. The TSSTcorp SH-S203B works properly.
+With BD-RE format 00h, the default is specified to be Quick Reformat,
+and with 00h in general certification can only be disabled not enabled.
+(mmc5r03c.pdf 6.5.4.2.1.7)
+
+
+-------------------------------------------------------------------------------
+DVD-RAM and BD-RE tuning :
+
+A special aspect of DVD-RAM and BD-RE is their low speed with write operations,
+which usually is only half than the nominal speed of media and drive.
+This is blamed to the automatic checkreading which happens for managing
+eventual defects. 
+
+Defect management of BD-RE can be disabled by format type 31h. See above.
+There is no drive known yet which would apply command 2Ah WRITE10 to DVD-RAM
+with full speed.
+
+The only known way to get full speed from DVD-RAM or BD-RE with enabled defect
+management is the use of AAh WRITE12 with Streaming Bit set to 1.
+(mmc5r03c.pdf 6.45)
+With some DVD-RAM drives this fails if a write buffer is not full 32 kB.
+With the tested BD-RE one has to write full 64 kB buffers.
+
+Although it seems not optimal, this is specified not only to disable the
+cumbersome checkread but also to ignore known defects and to write data
+to these defective addresses.
+(mmc5r03c.pdf 4.8.5)
+So the speed-up is only advisable as long as the media are free of
+incorrectable errors.
+
+Caveat:
+MMC-5 does not guarantee AAh WRITE12 to work on DVD-RAM or BD-RE at all.
+None of the features of profiles 0012h and 0043h promises the existence of
+AAh WRITE12.
+(mmc5r03c.pdf 5.4.13, 6.45)
+Nevertheless it worked on all tested drives if proper alignment was observed.
+
+
+-------------------------------------------------------------------------------
+ISO 9660 multi-session emulation on overwriteable media :
+
+Overwriteable media provide a single overwriteable track which may grow up to
+the full media capacity. There is no builtin table-of-content which records
+the history of write sessions.
+mount -t iso9660 will use sbsector=0 as default.
+The term "superblock" shall depict the first 64 KiB after the sbsector address.
+
+ISO 9660 multi-session depends on typical TOC information in two ways:
+It needs the superblock address MSC1 of the most recently recorded session and
+it needs the Next Writeable Address NWA for which to prepare the adress offset.
+
+The following is learned from growisofs and from ECMA-119:
+http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-119.pdf
+
+ISO 9660 filesystems provide information about the number of sectors which
+is also the lowest unused block address and thus a suitable NWA.
+This block address is stored in the Primary Volume Descriptor which is supposed
+to be stored in block 16 (eventually relative to MSC1).
+The bytes 0 to 5 of a PVD block are 
+   0x01 'C' 'D' '0' '0' '1'
+The sector count can then be read from byte 80 to 83
+   sectors= pvd[80] | (pvd[81] << 8) | (pvd[82] << 16) | (pvd[83] << 24);
+(Ecma-119.pdf 8.4)
+To support CD, DVD and BD media alike, it is advisable to round the NWA
+to the next multiple of 32 (= 64 KiB).
+
+So one can use 0 as MSC1 and prepare a new ISO session for the computed NWA.
+After writing the session it is necessary to patch the PVD at LBA 16.
+The minimal change would be to update the number of image sectors.
+It is stored in both notations LSB and MSB:
+   for(i= 0; i < 4; i++)
+     pvd[87 - i]= pvd[80 + i]= (sectors >> (8 * i)) & 0xff;
+
+cdrskin --grow_overwriteable_iso not only patches the sector fields of the
+PVD block but also the blocks up to LBA 31 which begin with
+   0xff 'C' 'D' '0' '0' '1'
+libisoburn submits 64 KiB data buffer to libisofs before image generation and
+afterwards writes these 64 KiB as new superblock to LBA 0.
+
+
+-------------------------------------------------------------------------------
+ISO 9660 based TOC emulation on overwriteable media :
+
+Above method of multi-session emulation yields a single session image after
+each add-on session. No reliable session history can be read because the
+sector size of the existing session gets overwritten by the new one.
+A TOC with session history is nevertheless desirable with incremental backups
+in order to access older backup states by mounting older superblocks at the
+start addresses of older sessions.
+
+All usual ISO 9660 formatter programs write a complete superblock to the
+start of each session.
+With a uniform NWA rounding rule it is possible to compute the address of
+superblock N+1 as the NWA after session N. The only problem is N=1
+because it gets overwritten by later sessions.
+
+libisoburn preserves the information of session 1 by writing the first session
+to LBA 32 rather than LBA 0. Afterwards it writes the overall superblock to
+LBA 0 (up to 31).
+So with all further add-on sessions the superblock at LBA 0 will enclose the
+overall image, while the superblocks of the sessions form a chain beginning
+at LBA 32. Each session superblock points to the next one by its sector count
+rounded up to 32. The chain end is marked by the overall image size.
+This chain gives the start addresses of sessions. The sector count minus start
+address gives the size of a particular session. ECMA-119 explains how to
+retrieve more info from the PVD (e.g. the volume id).

+About blank, appendable and finalized DVD+R :
+
+In the beginning a DVD+R holds an empty session and the Incomplete Fragment.
+From these one may spawn reserved fragments or one may write directly to
+the incomplete fragment. As soon as this is done the empty session becomes the
+open session which finally needs to get closed. By closing fragments and
+session a new empty session with empty Incomplete Fragment gets spawned.
+So the disc stays appendable.
+
+A DVD+R may hold 153 closed sessions with a single track each.
+The open session may hold up to 15 open fragments. But on closure of the
+session those fragments together form a single logical track.  So one will
+usually only use a single fragment for sequential writing. 
+(mmc5r03c.pdf 4.3.6.2)
+
+The disc may get finalized by another close command so that no more data can
+be written.
+(mmc5r03c.pdf 6.3.3.4.4) 
+
+
+-------------------------------------------------------------------------------
+Writing a Pseudo Session to DVD+R :
+
+Session writing has to be pseudo because only one logical track per session
+can be distinguished. So actually there have to be written multiple sessions
+to mark multiple tracks. The pseudo session cannot get marked on disc and thus
+the tracks of a pseudo session cannot be grouped accordingly in a TOC.
+
+Speed can be influenced by B6h SET STREAMING , speed capabilities can be
+inquired by ACh GET PERFORMANCE. It is advised to set only speeds and sizes
+which are returned by ACh.

+Note: growisofs has code for that gesture but explicitly avoids to use it, if

+-------------------------------------------------------------------------------
+SRM Formatting:
+
+Despite being write-once media BD-R can optionally carry some formatting.
+
+SRM has a disc structure model with tracks and sessions.
+Several tracks may be open at the same time, each having its own NWA.
+(mmc5r03c.pdf 4.5.3.5.2.2)
+This structure is formatted onto blank media automatically as soon as the
+first serious write attempt occurs.
+(mmc5r03c.pdf 4.5.3.5)
+Before such a write attempt, blank media may be explicitely formatted with
+spares, which provide defect management.
+(mmc5r03c.pdf 4.5.3.5.3)
+Tracks get created from other tracks via RESERVE TRACK splitting.
+(mmc5r03c.pdf 4.5.3.5.2.5)
+
+On top of defect management there may be Pseudo-OverWrite SRM+POW, a costly
+way to write several times to the same LBA. See below.
+Fully sequential states are called SRM-POW.
+(mmc5r03c.pdf 4.5.3.5.4)
+
+Explicite formatting is done by 04h FORMAT UNIT. Its data payload consists
+of a Format List Header and a Format Descriptor. It is advisable to set
+the Immed bit and the FOV bit in header byte number 1. The descriptor should
+be a copy of a descriptor from 23h READ FORMAT CAPACITIES but the size may be
+adjusted within a certain range.
+(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
+
+Format type 00h creates SRM layouts with a default number of spares (or
+eventually RRM) chosen by the format sub-type:
+  00b = SRM with support for POW
+  01b = SRM without POW (but with some spares for defect management)
+  10b = (RRM)
+(mmc5r03c.pdf 6.5.4.2.1.6)
+
+Format type 32h uses the same sub-types but allows to allocate non-default
+amounts of spares. Similar to BD-RE format 31h, three format descriptors are
+offered: #1: default size, #2: maximum spare area, #3: minimal spare.
+The size may be chosen within that range.
+
+The sense behind the Type Dependent Parameters is obscure
+to me. Best will be to set ISA_V and TDMA_V to 0.
+(mmc5r03c.pdf 6.5.4.2.1.17)
+
+
+-------------------------------------------------------------------------------
+Writing a session in SRM:
+
+The procedure and constraints for writing BD-R SRM-POW are very similar to
+DVD+R. libburn flatly re-uses its DVD+R code except the Close Function for
+finalizing a disc.
+
+In short:
+If all written sessions are closed, then there is exactly one NWA.
+In the beginning there is an empty session and track. A new track can be
+written either with pre-announced size (by RESERVE TRACK) or open-end by
+simply starting to write to the NWA. When done the track gets closed by
+close function 001b. Then either session or disc gets closed depending on
+the Close Function used:
+- Close Function 010b closes the session and keeps the media appendable
+  (same as with DVD+R)
+- Close Function 110b finalizes the media and makes it read-only.

+
+POW establishes a virtual vLBA space on top of the real address space rLBA.
+All read and write commands deal with vLBA. It seems that track NWAs are
+assumed to be identical in vLBA space and in rLBA space.
+It is not clear whether one may write to vLBA blocks which are neither written
+yet nor at one of the track NWAs. Probably not, or else one could make NWAs run
+into vLBAs which are associated with older rLBAs.
+
+Replacing invalidated blocks consumes addresses in rLBA space at the NWA of
+some track. I.e. no spares are consumed by POW. Nevertheless it is costly by
+a special map called Orphanage. It covers rLBA which have been consumed
+by differing vLBAs. It never shrinks and can grow with each write to remapped
+addresses.
+To avoid heavy Orphanage growth it is advised to write mostly to vLBA which
+still coincide with their rLBA. E.g. those addresses which have neither been
+written as rLBA nor as vLBA yet. So one should begin the vLBA of new sessions
+at the NWA of a sufficiently sized track.

+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() 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.

+
+   The output has been compared with the output of the old code of libburn

+
+
+                            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

+Description of the helper program stic*/bin/cgen
+
+cgen is copyright 2001 to 2007, Thomas Schmitt <stic-source@gmx.net>
+and provided under BSD license.
+
+Compilation:
+  cc -g -o cgen cgen.c ctyp.c smem.c
+
+
+cgen produces a class stub in C programming language. The data structure of
+the class is described by some lines which get read from stdin. The stub will
+consist of four files which emerge in the current working directory:
+ <classname>.h          public header file of the class
+ <classname>.c          automatically generated C code of the class
+                        plus a copy of <classname>.c.methods
+ <classname>_private.h  private header file of the class
+ <classname>.c.methods  safe storage for manually created functions.
+                        From here they get copied into the generated stub.
+                        If such a file is missing, a dummy gets created.
+It will define a struct <ClassnamE> for representing the class data aspects,
+construtor <Classname>_new(), destructor <Classname>_destroy(),
+getter <Classname>_<element>_get() for each structure element.
+Some more functions get added for particular class and element roles.
+
+cgen normally refuses to overwrite existing files because it supposes that
+those contain code added by the human programmer. 
+Human programmer enhancements may be explanatory comments, class specific
+methods, initial element values and other special precautions within the
+generated functions.
+As long as the modelling phase is going on, one may store such human code
+in <classname>.c.methods and may use command line option -overwrite for
+modelling development cycles.
+
+At some point of model matureness one may decide to give up cgen and the
+.c.method files and to go on only with _private.h , .h and .c files.
+
+
+Command line options
+
+  -no_stic   prevents usage of stic_dir/s_tools/*.[ch]
+
+  -ansi      generates ANSI C function heads and makes file <classname>.h hold
+             only public definitions: an opaque declaration of the class struct
+             and a list of function prototypes. The definiton of the class
+             struct is then in <classname>_private.h .
+  -global_include filename
+             sets the name of a file which will contain globally necessary
+             declarations. Currently it lists the existence of all class
+             structs.
+  -lowercase generate struct <classname> rather than struct <ClassnamE> and
+             function names <classname>_func() rather than <Classname>_func() .
+  -overwrite allows to overwrite files <classname>_private.h, <classname>.h
+             and <classname>.c, but not <classname>.c.methods.
+
+
+Input line format:
+
+There are two states of input: class level and element level.
+Exampes are shown below with class roles and element roles.
+
+Input starts at class level. A class level line may be one of
+
+- Comment. A line which begins with '#' is ignored on class level.
+
+- Empty. A line with no characters is a comment with empty text (i.e. ignored).
+
+- Class. Options which begin with '-' and finally a word in lowercase letters
+  which defines the <classname>. The classname leads to a struct ClassnamE
+  and some class methods implemented as C functions <Classnname>_<func>().
+
+- End of input. Line "@@@" or EOF at stdin end the program run.
+
+After a class line, input switches to element level where a line may be:
+
+- Comment. A line which after some white space begins with '#' is considered
+  a comment. The preceeding white space is ignored and the text after '#' is
+  eventuellay trimmed by a single blank at both ends. This text will be part
+  of the class struct definition within file <classname_private>.h as a single
+  C comment line /* ... */. The sequence of elements and comments is preserved.
+  An empty comment text leads to an empty line in <classname_private>.h.
+
+- Empty. A line with no characters is a comment with empty text.
+
+- Element. Options which begin with '-', eventual C keywords "unsigned" or
+  "volatile", type or "struct <NamE>", element name. This leads to a struct
+  element which is taken into respect in some class methods. Depending on the
+  options in this line, some element methods <Classnname>_<func>_<element>()
+  may get generated.
+
+- End of class. A single '@' marks the end of the element list and brings
+  input back to class level. I.e. next is expected another class name or
+  "@@@" or EOF at stdin.
+
+Input semantics:
+
+A class can have one of two roles:
+
+- Standalone class.
+  Input example:
+    my_class
+
+- Listable class, which has pointers to peer instances: .prev and .next
+  Such classes get a list destructor <Classname>_destroy_all() which destroys
+  all members of a list (which is given by any of the list members).
+  Such a class should have a pointer *boss as first element in which case
+  the constructor will look like
+    <Classname>_new(struct <ClassnamE> **o,struct <Some_clasS> *boss,int flag);
+  There is a function <Classname>_link() which inserts an instance into a list
+  and a function <Classname>_count() which tells the number of list members.
+  For pseudo random access there is function <Classname>_by_idx().
+  Input example:
+    -l my_class
+
+
+A modifier is defined for classes:
+
+- Bossless. Disables a special boss-subordinate relationship which is created
+  if the first element of a class is a struct pointer with the name "boss".
+  Like
+    -l <classname>
+    -v struct Some_clasS *boss
+  Normally such a parameter *boss becomes part of the constructor method
+    <Classname>_new(struct <ClassnamE> **o, struct Some_clasS *boss, int flag);
+  This relationship is typical for a listable class and a single class which
+  is designed to host instances of that listable class. Therefore one gets a
+  warning if a listable class does not begin with a struct pointer *boss.
+  But if -b is given, then CgeN ill not include a parameter *boss into the
+  constructor. It will rather look normal:
+    <Classname>_new(struct <ClassnamE> **o, int flag);
+  It will not warn if the first element of a listable class is not struct
+  pointer *boss.
+
+
+Elements have one of the following roles:
+
+- Value. It provides only storage for a C data type (which may be a C pointer
+  despite the role name "value"), a getter method <Classname>_<element>_get(),
+  and a setter method <Classname>_<element>_set().
+  Input examples:
+    -v int i
+    -v int a[100]
+    -v char *cpt
+    -v struct xyz x
+    -v struct xyz *xpt
+
+- Managed. This has to be a pointer to a struct <XyZ> or to char. It will not
+  get attached to an object by the stub's code but its destructor
+  <Xyz>_destroy() will be called by <Classname>_destruct(). In case of (char *)
+  it is supposed that a non-NULL value has been allocated by malloc().
+  Managed (char *) types get a setter function <Classname>_<element>_set()
+  which allocates memory and copies the textstring from its parameter.
+  Input examples:
+    -m struct XyZ *xyzpt
+    -m char *textstring
+
+- Chainlink. A pair of prev-next-style pointers to the own class struct.
+  Function <Classname>_destruct() will unlink the affected instance and
+  put together its link partners.
+  Input example (there must always be two consequtive -c lines):
+    -c struct My_clasS *up
+    -c struct My_clasS *down
+
+- List. A pair of pointers to the struct <XyZ> of a listable class. The first
+  one <ls> holds the start of the list, the second one <eol> holds the end.
+  The getter function has an additional argument idx:
+    <Classname>_get_<ls>(struct <ClassnamE> *o, int idx, struct <XyZ> **pt,
+                         int flag)
+  idx == 0 is the start of the list, idx=1 the next element, ...
+  idx == -1 retrieves the last element of the list.
+  For insertion of list items there is provided method <Classname>_new_<ls>().
+  The inserted item is reachable via the getter function with idx == -1
+  <Classname>_destroy() instance calls <Xyz>_destroy_all(). Note that the end
+  pointer is always generated as private element (-p).
+  Input example (there must always be a -l and a -v line):
+    -l struct XyZ *list_start
+    -v struct XyZ *list_end
+
+The availability of getter method <Classname>_get_<element>(), and setter
+method <Classname>_set_<element>_set() can be controled by two modifiers:

+- Readonly. Only a getter method.
+  Input example
+    -r -v int broadcasted_status
+
+- Private. Neither getter nor setter method.
+  Input example
+    -p -v int private_value
+
+- Bossless listable. This marks elements which are listable objects but do not
+  expect a boss pointer in their constructor. See above: Listable class and
+  the bossless modifier for classes.
+  Input example
+    -b -l struct XyZ *list
+    -v struct XyZ *last_in_list
+
+- Initialization free. The class constructor will not initialize this element.
+  This modifier has to be used if neither NULL nor 0 are suitable
+  initialization values.

+# libdax is the early working name for the successor software of libburn,
+# a library for writing information onto optical media, i.e. CD and DVD.
+# The current working name is libcevap, refering to various kinds of roasts in
+# Europe and Asia which share the property to be structured in smaller pieces.
+#
+# The reason for the replacement is the unclear copyright situation as well
+# as libburn's sketchy original state and the subsequential evolutionary
+# damages done by us in libburn code.
+# This does not mean libburn is shaky. Its current state just reflects the
+# virtual conflict of at least two programmer personalities and their goals.
+#
+
+#
+# Please: Nobody shall take the development of libcevap as a reason for not
+# programming an application which uses libburn.
+# libburn works now. libcevap is planned to work in future.
+#
+# libcevap will replace libburn in a controlled, application friendly way.
+# The first application of libcevap will be a libburn API wrapper which will
+# allow to perform all API calls of libburn which are proveable to work in
+# the current implementation. (Some CD stuff is not understood by us yet.
+# We will have to learn.)
+#
+# The libburn API will be frozen when libcevap has closed up to its current
+# capabilities. Nevertheless it may take profit from some of the future
+# progress in libcevap (e.g. new media types).
+# We hope that finally libcevap will have capabilities superior to libburn.
+# This will then be a reason to port applications to the libcevap API.
+#
+# Application programmers are advised to encapsulate their libburn API calls
+# in an own abstraction layer. The semantic concepts of burning will be
+# compatible between libburn and libcevap. I.e you will have a library object
+# to be started up, drives to be found and grabbed, media and their states
+# to be identified, sessions, tracks, burn options to be set, blanking,
+# formatting, and so on.
+# Data types, function calls, and quirks will be incompatible between both
+# APIs, though.

+ Functions to replace  malloc()  and  free() in order to get more control
+ over memory leaks or spurious errors caused by faulty usage of malloc()
+ and free(). 
+
+
+ Sourcecode provisions:
+ 
+ Use only the following macros for memory management:
+    TSOB_FELD(type,count)  creates an array of items of given type 
+    Smem_malloC()          analogue of malloc()
+    Smem_freE()            analogue of free()
+ One may #define malloc Smem_malloC resp. #define free Smem_freE 
+ but better would be to review (and often to streamline) the sourcecode
+ in respect to those two functions. 
+
+
+ Speed versus control:
+
+ In production versions, where maximum speed is required, one may undefine
+ the macro  Smem_own_functionS  in  smem.h . 
+ This causes the above macros to directly invoke malloc() and free() without
+ any speed reduction (and without any additional use).
+ Undefinitio can be done globaly by modifying smem.h or locally by defining
+  Smem_no_own_functionS  before including smem.h .
+
+ If Smem_own_functionS remains defined, then the functions
+   Smem_malloc() 
+   Smem_free()
+ are used rather than malloc() and free().
+ They count the number of calls to maintain a rough overview of memory usage.
+ Smem_malloc() additionally checks for 0 size and Smem_free() checks for
+ NULL pointers, which they both report to stderr. Eventually one should set
+ a breakpoint in function Smem_protest() to learn about the origin of such
+ messages.
+ A status line may be obtained by  Smem_report()  or printed by Smem_stderr().
+
+ As long as the variable Smem_record_itemS is set to 0, there is not very much
+ overhead compared with malloc() and free().
+ If the variable is set to 1 by Smem_set_record_items() then all malloc()
+ results are kept in a list where they will be deleted by their corresponding
+ Smem_free() calls. If a pointer is to be freed, which is not recorded in the
+ list then an error message will be printed to stderr. The memory will not
+ be freed !
+ This mode not only may be very slow, it also consumes at least 16 byte per
+ piece of data which was obtained by malloc as long as it has not been freed.
+ Due to the current nature of the list, large numbers of memory items are freed
+ much faster in the reverse order of their creation. If there is a list of
+ 100000 strings to delete, it is very rewarding to free the youngest ones first.
+ A shortcut via hashing is available but consumes 24 bytes rather than 16.
+ (see above  Smem_with_hasH  )
+
+ The function Smem_is_recorded() can be used to check wether a pointer is
+ valid according to the list. It returns :
+   0 = is not in list , 1 = is in list , 2 = recording is off 
+
+ If one decides to start recording malloc() results in the midst of a program
+ run, one has to be aware of false protests of Smem_free() if a memory piece
+ has been allocated before recording started. This will also cause those pieces
+ to be memory leaks because Smem_free() refuses to delete them. (Freeing memory
+ that was not obtained by malloc or was already freed previously can result in
+ deferred SIGSEGV or similar trouble, depending on OS and library.)
+ Also in that case one should stop recording before ending the program, to
+ avoid a lot of false complaints about longliving memory objects.
