+Installation Instructions
+*************************
+

+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:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`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.

+
+libburnia.pykix.org is an open-source software project for reading, mastering
+and writing optical discs.
+For now this means only CD media and all single layer DVD media except DVD+R.

 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.

-Our scope is currently Linux 2.4 and 2.6 and we will have a hard time to widen
-this for now, because of our history. The project could need advise from or
-membership of skilled kernel people and people who know how to talk CD/DVD
-drives into doing things.
+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.

-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.

+
+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 only some syntax of addresses but not the meaning

+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 device file /dev/s[rg]N 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'

+
 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.
-To direct such 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"-1,1,0 \
+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

                                  Audio CD

-Builtin extraction of raw audio data from filetypes .au and .wav is not
-implemented yet. Lorenzo Taylor enabled option -audio in cdrskin (thanks !)
-and reports neat results with audio data files which are :
-  headerless 
-  44100Hz 
-  16bit, stereo (or 4-channel if the 4-channel bit is set),
-  little-endian byte order
-He proposes to extract them from usual audio formats by commands like
-given above under "Usage examples".
+Lorenzo Taylor enabled option -audio in cdrskin (thanks !) and reports neat
+results with audio data files which are :
+  headerless PCM (i.e. uncompressed)
+  44100 Hz sampling rate 
+  16 bits per sample
+  stereo (2 channels)
+  little-endian byte order with option -swab, or big-endian without -swab
+
+Files with name extension .wav get examined wether they are in Microsoft WAVE
+format with above parameters and eventually get extracted by cdrskin itself.
+In the same way files with name extension .au get examined wether they are
+in SUN's audio format. For both formats, track format -audio and eventual
+endianness option -swab are enabled automatically.
+
+Any other formats are to be converted to format .wav with above parameters
+or to be extracted as raw CD track data by commands like those given above
+under "Usage examples". Those raw files need option -audio and in most cases 
+option -swab to mark them as little-endian/Intel/LSB-first 16-bit data.
+Incorrect endianness setting results in random noise on CD.

-The existence of cdrecord-builtin .wav extraction seems to have
-hampered the development of a standalone stripping tool. If you know
-a command line that would do the trick, contact me or libburn.pykix.org .
 I myself am not into audio. So libburn-hackers@pykix.org might be the
 best address for suggestions, requests and bug reports.


+                             DVD+RW and DVD-RAM
+
+DVD+RW and DVD-RAM 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). Currently
+there is no difference between -sao and -tao. If ever, then -tao will be the
+mode which preserves the current behavior.
+
+For these media, -msinfo alone would not be enough to perform appending of an
+ISO filesystem. The filesystem driver will need a hint to find the start of the
+most recent session. For example put an ISO filesystem at address 1 GB:
+  mkisofs -C 0,524288 ... | \
+  cdrskin dev=/dev/sr0 -v fs=32m -eject speed=4 write_start_address=524288s -
+The superuser may then do:
+  mount -t iso9660 -o ro,sbsector=524288 /dev/sr0 /mnt
+Note: On my linux-2.4.21-215 mount works only with sbsector <= 337920 (660 MiB)
+To extend a filesystem already existing at address 0
+  mkisofs -C 0,524288 -M /dev/sr0 ... | cdrskin dev=/dev/sr0 ...
+Record the number 524288 for usage as first number with -C at the next
+extension:
+  mkisofs -C 524288,1000000 ... | cdrskin write_start_address=1000000s ...
+
+Program growisofs can append to an ISO filesystem on DVD+RW by additionally
+manipulating the first session. cdrskin does not want to get involved so deep
+into the format of the burned data. Be advised to use growisofs for the
+task of maintaining extendable ISO-Filesystems on DVD+RW. 
+
+
+                               DVD-RW and DVD-R
+
+DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
+"Sequential Recording". DVD-R are always in sequential state.
+
+"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 
+
+From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
+into an own session, though.

+.\" TeX users may be more comfortable with the \fB<whatever>\fP and
+.\" \fI<whatever>\fP escape sequences to invode bold face and italics, 
+.\" respectively.
+.PP 
+\fBcdrskin\fP is a program that provides some of cdrecord's options
+in a compatible way for CD media. With DVD it has its own ways.
+You do not need to be superuser for its daily usage.
+.PP
+.B Overview of features:
+.br
+Blanking of CD-RW and DVD-RW.
+.br
+Burning of data or audio tracks to CD,
+.br
+either in versatile Track at Once mode (TAO)
+.br
+or in Session at Once mode for seamless tracks.
+.br
+Multi session on CD (follow-up sessions in TAO only)
+.br
+or on DVD-R[W] (in Incremental mode) or on DVD+R.
+.br
+Single session on DVD-RW or DVD-R (Disk-at-once)
+.br
+or on overwriteable DVD+RW, DVD-RW, DVD-RAM.
+.br
+Bus scan, burnfree, speed options, retrieving media info, padding, fifo.
+.br
+See section EXAMPLES at the end of this text.

+.br

+Write mode selection
+.br

+.br
+Sequentially Recordable DVD Media
+.br
+Overwriteable DVD Media
+.br
+Drive preparation and addressing
+.PP
+.B Track recording model:
+.br
+The input-output entities which get processed are called tracks.
+A \fBtrack\fP stores a stream of bytes.
+.br
+Each track is initiated by one track source address argument, which may either
+be "-" for standard input or the address of a readable file. If no write mode
+is given explicitely then one will be chosen which matches the peculiarities
+of track sources and the state of the output media.
+.PP
+More than one track can be burned by a single run of cdrskin. 
+In the terms of the MMC standard all tracks written by the same run constitute
+a \fBsession\fP.
+.br
+Some media types can be kept appendable so that further tracks can
+be written to them in subsequent runs of cdrskin (see option -multi).
+Info about the addresses of burned tracks is kept in a table of
+content (TOC) on media and can be retrieved via cdrskin option -toc.
+These informations are also used by the operating systems' CD-ROM read drivers.
+.PP
+In general there are two types of tracks: data and audio. They differ in
+sector size, throughput and readability via the systems' CD-ROM drivers
+resp. by music CD players. With DVD there is only type data.
+.br
+If not explicitely option -audio is given, then any track is burned as type
+data, unless the track source is a file with suffix ".wav" or ".au" and has a
+header part which identifies it as MS-WAVE resp. SUN Audio with suitable
+parameters. Such files are burned as audio tracks by default.
+.PP
+While audio tracks just contain a given time span of acoustic vibrations,
+data tracks may have an arbitray meaning. Nevertheless, ISO-9660 filesystems
+are established as a format which can represent a tree of directories and
+files on all major operating systems. Such filesystem images can be
+produced by programs mkisofs or genisoimage. They can also be extended by
+follow-up tracks if prepared properly. See the man pages of said programs.
+cdrskin is able to fulfill the needs about their option -C.
+.br
+Another type of data track content are archive formats which originally
+have been developed for magnetic tapes. Only formats which mark a detectable
+end-of-archive in their data are suitable, though. Well tested are
+the archivers afio and star. Not suitable seems GNU tar.
+.PP
+.B Write mode selection:
+.br
+If none of the options -dao, -tao or -sao is given then the program will
+try to choose a write mode which matches the defined recording job,
+the capabilities of the drive and the state of the present media.
+.br
+So the mentioning of write modes in the following paragraphs and in the
+examples is not so much a demand that the user shall choose one explicitely,
+but rather an illustration of what to expect with particular media types.
+.PP
+.B Recordable CD Media:
+.br
+CD-R can be initially written only once and eventually extended until they
+get closed (or are spoiled because they are overly full). After that they are
+read-only. Closing is done automatically unless option
+.B -multi
+is given which keeps the media appendable.
+.br
+There are two write modes,
+.B -tao
+and
+.B -sao .
+.br
+-tao allows to use track source of unpredictable length (like stdin) and allows
+to write further sessions to appendable media. -sao produces audio sessions
+with seamless tracks but needs predicted track sizes and cannot append sessions
+to media.
+.br
+CD-RW media can be blanked to make them re-usable for another
+round of overwriting. Usually
+.B blank=fast
+is the appropriate option.
+Blanking damages the previous content but does not
+make it completely unreadable. It is no effective privacy precaution.
+Multiple cycles of blanking and overwriting with random numbers might be.
+.PP
+.B Sequentially Recordable DVD Media:
+.br
+Currently DVD-RW, DVD-R and DVD+R can be used for the Sequential recording
+model.
+.br
+DVD-RW must be in state "Sequential Recording".
+The media must be either blank or appendable.
+Newly purchased DVD-RW and DVD-R media are in this state.
+Used DVD-RW get into blank sequential state by option
+.B blank=deformat_sequential .
+.br
+With DVD-R[W] two write modes may be available:
+.br
+Mode DAO has many restrictions. It does not work with
+appendable media, allows no -multi and only a single track. The size of the
+track needs to be known in advance. So either its source has to be a disk file
+of recognizable size or the size has to be announced explicitely by options
+.B tsize= 
+or
+.B tao_to_sao_tsize= .
+.br
+DAO is the only mode for media which do not offer feature 21h Incremental
+Streaming. DAO may also be selected explicitely by option
+.B -sao .
+Program growisofs uses DAO on sequential DVD-R[W] media for maximum
+DVD-ROM/-Video compatibility.
+.br
+The other mode, Incremental Streaming, is the default write mode if
+it is available and if the restrictions of DAO would prevent the job.
+Incremental Streaming may be selected explicitely by option
+.B -tao
+as it resembles much CD TAO by allowing track sources of
+unpredicted length and to keep media appendable by option
+.B -multi .
+The only restriction towards CD-R[W] is the lack of support for -audio tracks.
+Multiple tracks per session are permissible.
+.br
+The write modes for DVD+R resemble those with DVD-R except that with DVD+R
+each track gets wrapped in an own session. There is no -dummy writing with
+DVD+R.
+.br
+Quite deliberately write mode -sao insists in the tradition of a predicted
+track size and blank media, whereas -tao writes the tracks open ended and
+allows appendable media.
+.PP
+.B Overwriteable DVD Media:
+.br
+Currently types DVD+RW, DVD-RW and DVD-RAM can be overwritten via cdrskin.
+.br
+DVD+RW and DVD-RAM media get treated as blank media regardless wether they
+hold data or not. They need no special initial formatting.
+Options -audio and -multi are not allowed. Only one track is allowed.
+-toc does not return information about the media content.
+Currently there is no difference between -sao and -tao. If ever, then -tao
+will be the mode which preserves the current behavior.
+.br
+DVD-RW are sold in state "Sequential Recording". To become suitable for the
+Overwriteable DVD recording model they need to get formatted to state
+"Restricted Overwrite". Then they behave much like DVD+RW. This formatting
+can be done by option
+.B blank=format_overwrite .
+.br
+Several programs like dvd+rw-format, cdrecord, wodim, or cdrskin
+can bring a DVD-RW out of overwriteable state so
+that it has to be formatted again. If in doubt, just give it a try.
+.PP
+.B Drive preparation and addressing:
+.br
+The drives, either CD burners or DVD burners, are accessed via addresses which
+are specific to libburn and the operating system. Those addresses get listed
+by a run of \fBcdrskin --devices\fP.
+.br
+On Linux, they are device files which traditionally do not offer
+w-permissions for normal users. Because libburn needs rw-permission,
+it might be only the
+.B superuser
+who is able to get this list without further
+precautions.
+.br
+It is consensus that \fBchmod a+rw /dev/sr0\fP or \fBchmod a+rw /dev/hdc\fP
+is less security sensitive than chmod u+s /usr/bin/cdrskin. The risk for the
+drive is somewhat higher but the overall system is much less at stake.
+.br
+.PP
+If you only got one CD capable drive then you may leave out cdrskin option
+\fBdev=\fP. Else you should use this option to address the drive you want.
+.br
+cdrskin option dev= not only accepts the listed addresses but also
+traditional cdrecord SCSI addresses which on Linux consist of three
+numbers: Bus,Target,Lun. There is also a related address family "ATA" which
+accesses IDE drives not under control of Linux SCSI drivers:
+ATA:Bus,Target,Lun.
+.br
+See option -scanbus for getting a list of cdrecord style addresses.
+.br
+Further are accepted on Linux: links to libburn-suitable device files, 
+device files which have the same major and minor device number,
+and device files which have the same SCSI address parameters (e.g. /dev/sg0).
+.br
+.SH OPTIONS

+.BI \-help
+Show cdrecord compatible options.
+.TP
+.BI \-version
+Print cdrskin id line, compatibility lure line, libburn version, cdrskin
+version, version timestamp, build timestamp (if available), and then exit.
+.PP
+Alphabetical list of options which are intended to be compatible with
+original cdrecord by Joerg Schilling:
+.TP
+.BI \-atip
+Retrieve some info about media state. With CD-RW print "Is erasable".
+With DVD media print "book type:" and a media type text.
+.TP 
+.BI \-audio
+Announces that the subsequent tracks are to be burned as audio.
+The source is supposed to be uncompressed headerless PCM, 44100 Hz, 16 bit,
+stereo. For little-endian byte order (which is usual on PCs) use option
+-swab. Unless marked explicitely by option -data, input files with suffix
+".wav" are examined wether they have a header in MS-WAVE format confirming
+those parameters and eventually raw audio data get extracted and burned as
+audio track. Same is done for suffix ".au" and SUN Audio.
+.br
+Option -audio may be used only with CD media and not with DVD.
+.TP 
+.BI blank= type
+Blank a CD-RW, a DVD-RW, or format a DVD+/-RW.
+This is combinable with burning in the same run of cdrskin.
+The type given with blank= selects the particular behavior:
+.RS
+.TP
+help
+Print this list of blanking types.
+.TP
+all
+Blank an entire CD-RW or an unformatted DVD-RW.
+(See also --prodvd_cli_compatible)
+.TP
+fast
+Minimally blank an entire CD-RW or blank an unformatted DVD-RW.
+(See also --prodvd_cli_compatible)
+.TP
+format_overwrite
+Format a DVD-RW to "Restricted Overwrite". The user should bring some patience.
+.br
+(Note: blank=format_overwrite* are not original cdrecord options.)
+.TP
+format_overwrite_quickest
+Like format_overwrite without creating a 128 MiB trailblazer session.
+Leads to "intermediate" state which only allows sequential write
+beginning from address 0.
+The "intermediate" state ends after the first session of writing data.
+.TP
+format_overwrite_full
+For DVD-RW this is like format_overwrite but claims full media size
+rather than just 128 MiB.
+Most traditional formatting is attempted. No data get written. 
+Much patience is required.
+.br
+This option treats already formatted media even if not option -force is given.
+.br
+For DVD+RW this is the only supported explicit formatting type. It provides
+complete "de-icing" so no reader slips on unwritten data areas.
+.TP
+deformat_sequential
+Like blank=all but with the additional ability to blank overwriteable DVD-RW.
+This will destroy their formatting and make them sequentially recordable. 
+Another peculiarity is the ability to blank media which appear already blank.
+This is similar to option -force but does not try to blank media other than
+recognizable CD-RW and DVD-RW.
+.br
+(Note: blank=deformat_sequential* are not original cdrecord options.)
+.TP
+deformat_sequential_quickest
+Like blank=deformat_sequential but blanking DVD-RW only minimally.
+This is faster than full blanking but may yield media incapable of
+Incremental Streaming (-tao).
+.RE
+.TP
+.BI \-checkdrive
+Retrieve some info about the addressed drive.
+Exits with non-zero value if the drive cannot be found and opened.
+.TP
+.BI \-dao
+Alias for option -sao. Write CD in Session at Once mode
+or DVD-R[W] in Disc-at-once mode.
+.TP
+.BI \-data
+Subsequent tracks are data tracks. This option is default and only needed
+to mark the end of the range of an eventual option -audio.
+.TP
+.BI dev= target
+Set the address of the drive to use. Valid are at least the
+addresses listed with option --devices, 
+X,Y,Z addresses listed with option -scanbus,
+ATA:X,Y,Z addresses listed with options dev=ATA -scanbus,
+and volatile libburn drive numbers (numbering starts at "0").
+Other device file addresses which lead to the same drive might work too.
+.br
+If no dev= is given, volatile address "dev=0" is assumed. That is the first
+drive found being available. Better avoid this ambiguity on systems with more
+than one drive.
+.br
+The special target "help" lists hints about available addressing formats.
+Be aware that deprecated option --old_pseudo_scsi_adr may change the meaning
+of Bus,Target,Lun addresses.
+.TP
+.BI driveropts= opt
+Set "driveropts=noburnfree" to disable the drive's eventual protection
+mechanism against temporary lack of source data (i.e. buffer underrun).
+A drive that announces no such capabilities will not get them enabled anyway,
+even if attempted explicitely via "driveropts=burnfree".
+.TP
+.BI \-dummy
+Try to perform the drive operations without actually affecting the inserted
+media. There is no warranty that this will work with a particular combination
+of drive, media, and write mode. Blanking is prevented reliably, though.
+To avoid inadverted real burning, -dummy refuses burn runs on anything but
+CD-R[W] and DVD-R[W].
+.TP
+.BI \-eject
+Eject the disc after work is done.
+.TP
+.BI \-force
+Assume that the user knows better in situations when cdrskin or libburn are
+insecure about drive or media state. This includes the attempt to blank
+media which are classified as unknown or unsuitable, and the attempt to use
+write modes which libburn believes they are not supported by the drive.
+.br
+Another application is to enforce blanking or re-formatting of media
+which appear to be in the desired blank or format state already.
+.br
+This option enables a burn run with option -dummy even if libburn believes
+that drive and media will not simulate the write mode but will write for real.
+.br
+.B Caution:
+Use this only when in urgent need.
+.TP
+.BI fs= size
+Set the fifo size to the given value. The value may have appended letters which
+multiply the preceding number:
+.br
+"k" or "K" = 1024 , "m" or "M" = 1024k , "g" or "G" = 1024m , "s" or "S" = 2048
+.br
+Set size to 0 in order to disable the fifo (default is "4m").
+.br
+The fifo buffers an eventual temporary surplus of track source data in order to
+provide the drive with a steady stream during times of temporary lack of track
+source supply.
+The larger the fifo, the longer periods of poor source supply can be
+compensated.
+But a large fifo needs substantial time to fill up if not curbed via
+option fifo_start_at=size.
+.TP
+.BI gracetime= seconds
+Set the grace time before starting to write. (Default is 0)
+.TP
+.BI -isosize
+The next track following this option will try to obtain its source size from
+the header information out of the first few blocks of the source data.
+If these blocks indicate an ISO-9660 filesystem then its declared size
+will be used under the assumption that it is a single session filesystem.
+.br
+If not, then the burn run will be aborted.
+.br
+The range of -isosize is exactly one track. Further tracks may be preceeded
+by further -isosize options, though. At least 15 blocks of padding will be
+added to each -isosize track. But be advised to rather use padsize=300k.
+.br
+This option can be performed on track sources which are regular files or block
+devices. For the first track of the session it can be performed on any type
+of source if there is a fifo of at least 64 kiB. See option fs= .
+.TP
+.BI minbuf= percentage
+Equivalent to:
+.br
+modesty_on_drive=1:min_percent=<percentage>:max_percent=95
+.br
+Percentage is permissible between 25 and 95.
+.TP
+.BI msifile= path
+Run option -msinfo and copy the result line into the file given by path.
+Unlike -msinfo this option does not redirect all normal output away from
+standard output. But it may be combined with -msinfo to achieve this.
+.br
+Note: msifile=path is actually an option of wodim and not of cdrecord.
+.TP
+.BI \-msinfo
+Retrieve multi-session info for preparing a follow-up session by option -C
+of programs mkisofs or genisoimage. Print result to standard output.
+This option redirects to stderr all message output except the one of option
+--tell_media_space and its own result string, which consists of two numbers.
+The result string shall be used as argument of option -C with said programs.
+It gives the start address of the most recent session and the predicted
+start address of the next session to be appended. The string is empty if
+the most recent session was not written with option -multi.
+.TP
+.BI \-multi
+This option keeps the CD or unformatted DVD-R[W] appendable after the current
+session has been written.
+Without it the disc gets closed and may not be written any more  - unless it
+is a -RW and gets blanked which causes loss of its content.
+.br
+The following sessions can only be written in -tao mode. -multi is prohibited
+with overwriteable DVD media and with DVD-R[W] DAO write mode.
+Option --prodvd_cli_compatible eventually makes -multi tolerable but cannot
+make it work.
+.br
+In order to have all filesystem content accessible, the eventual ISO-9660
+filesystem of a follow-up
+session needs to be prepared in a special way by the filesystem formatter
+program. mkisofs and genisoimage expect particular info about the situation
+which can be retrieved by cdrskin option -msinfo.
+.br
+To retrieve an archive file which was written as follow-up session,
+you may use option -toc to learn about the "lba" of the desired track number. 
+.TP
+.BI \-nopad
+Do not add trailing zeros to the data stream. Nevertheless, since there seems
+to be no use for audio tracks with incomplete last sector, this option applies
+only to data tracks. There it is default.
+.TP
+.BI \-pad
+Add 30 kiB of trailing zeros to each data track. (This is not sufficient to
+avoid problems with various CD-ROM read drivers.)
+.TP
+.BI padsize= size
+Add the given amount of trailing zeros to the next data track. This option
+gets reset to padsize=0 after that next track is written. It may be set
+again before the next track argument. About size specifiers, see option fs=.
+.TP
+.BI \-raw96r
+Write CD in RAW/RAW96R mode. This mode allows to put more payload bytes
+into a CD sector but obviously at the cost of error correction. It can only
+be used for tracks of fixely predicted size. Some drives allow this mode but
+then behave strange or even go bad for the next few attempts to burn a CD.
+One should use it only if inavoidable.
+.TP
+.BI \-sao
+Write CD in Session At Once mode, a sequential DVD-R[W] in Disc-at-once
+(DAO) mode, or a DVD+R.
+.br
+With CD this mode is able to put several audio tracks on media without
+producing audible gaps between them.
+.br
+With DVD-R[W] this mode can only write a single track.
+No -multi is allowed with DVD-R[W] -sao.
+.br
+-sao is permissible with overwriteable DVD and with DVD+R but actually only
+imposes restrictions without providing known advantages. 
+.br
+-sao can only be used for tracks of fixely predicted size. This implies that
+track arguments which depict stdin or named pipes need to be preceeded by
+option tsize= or by option tao_to_sao_tsize=.
+.br
+-sao cannot be used on appendable media.
+.TP
+.BI \-scanbus
+Scan the system for drives. On Linux the drives at /dev/s* and at /dev/hd*
+are to be scanned by two separate runs. One without dev= for /dev/s* and
+one with dev=ATA for /dev/hd* devices. (Option --drives lists all available
+drives in a single run.)
+.br
+Drives which are busy or which offer no rw-permission to the user of cdrskin
+are not listed. Busy drives get reported in form of warning messages.
+.br
+The useful fields in a result line are:
+.br
+Bus,Target,Lun Number) 'Vendor' 'Mode' 'Revision'
+.TP
+.BI speed= number
+Set speed of drive. With data CD, 1x speed corresponds to a throughput of
+150,000 bytes/second. With DVD, 1x = 1,385,000 bytes/second.
+It is not an error to set a speed higher than is suitable for drive
+and media. One should stay within a realistic speed range, though.
+Special speed settings are:
+.br
+0 = minimal speed , -1 = maximal speed (default).
+.TP
+.BI \-swab
+Announce that the raw audio data source of subsequent tracks is byte swapped
+versus the expectations of cdrecord. This option is suitable for audio where
+the least significant byte of a 16 bit word is first (little-endian, Intel).
+Most raw audio data on PC systems are available in this byte order.
+Less guesswork is needed if track sources are in format MS-WAVE in a file with
+suffix ".wav".
+.TP
+.BI \-tao
+Write CD in Track At Once (TAO) mode, sequential DVD-R[W] in Incremental
+Streaming mode, or DVD+R without traditional -sao restrictions.
+This mode also applies pro-forma to overwriteable DVD media.
+.br
+Mode -tao can be used with track sources of unpredictable size, like standard
+input or named pipes. It is also the only mode that can be used for writing
+to appendable media which already hold data. With unformatted DVD-R[W] it is
+the only mode which allows -multi.
+.TP
+.BI \-toc
+Print the table of content (TOC) which describes the tracks recorded on disc.
+The output contains all info from option -atip plus lines which begin with
+"track:", the track number, the word "lba:" and a number which gives the
+start address of the track. Addresses are counted in CD sectors which with
+SAO or TAO data tracks hold 2048 bytes each.
+.RS

+.TP
+.BI tsize= size
+Announces the exact size of the next track source. This is necessary with any
+write mode other than -tao if the track source is not a regular disk file, but
+e.g. "-" (standard input) or a named pipe.
+About size specifiers, see option fs=.
+.br
+If the track source does not deliver the predicted amount of bytes, the
+remainder of the track is padded with zeros. This is not considered an error.
+If on the other hand the track source delivers more than the announced bytes
+then the track on media gets truncated to the predicted size and cdrskin exits
+with non-zero value.
+.TP
+.BI \-v
+Increment verbose level by one. Startlevel is 0 with only few messages.
+Level 1 prints progress report with long running operations and also causes
+some extra lines to be put out with info retrieval options. 
+Level 2 additionally reports about option settings derived from arguments or
+startup files. Level 3 is for debugging and useful mainly in conjunction with
+somebody who had a look into the program sourcecode.
+.PP
+Alphabetical list of options which are genuine to cdrskin and intended for
+normal use:
+.TP
+.BI \--adjust_speed_to_drive
+Curb explicitely given speed= values to the maximum which is announced by the
+drive for the loaded media. By default, such an adjustment is only made with
+pseudo-speeds 0 and -1 whereas speed settings > 0 are sent unchanged to the
+drive which will then choose an appropriate speed on its own.
+.TP
+.BI \--allow_setuid
+Disable the loud warning about insecure discrepance between login user and
+effective user which indicates application of chmod u+s to the program binary.
+One should not do this chmod u+s , but it is an old cdrecord tradition.
+.TP
+.BI \--any_track
+Allow source_addresses to begin with "-" (plus further characters) or to
+contain a "=" character.
+By default such arguments are seen as misspelled options. It is nevertheless
+not possible to use one of the options listed with --list_ignored_options.
+.TP
+.BI assert_write_lba= block_number | byte_address
+Abort if the write address given with this option is not the same as predicted
+immediately before the write session starts. This option can ensure that a
+start address which was presumed by a formatter like mkisofs -C is really used
+by the drive for writing.
+assert_write_lba=0 effectively demands blank media and excludes appendables.
+.br
+Block numbering is peculiar: If the last character of the option string is
+a letter [a-zA-Z] then the usual unit scaling by "s", "k", "m", etc. applies
+and the result is divided by 2048. Else the number value of the string is
+taken as plain block number with block size 2048 byte.
+(E.g ...=1000 or ...=1000s means block 1000, ...=1m means block
+512, ...=4096b means block number 2)
+.TP
+.BI \--demand_a_drive
+Exit with a nonzero value if no drive can be found during a bus scan.
+.TP
+.BI \--devices
+List the device file addresses of all accessible CD drives. In order to get
+listed, a drive has to offer rw-permission for the cdrskin user and it may
+not be busy. The superuser should be able to see all idle drives listed and 
+busy drives reported as "SORRY" messages.
+.br
+Each available drive gets listed by a line containing the following fields:
+.br
+Number dev='Devicefile' rw-Permissions : 'Vendor' 'Model'
+.br
+Number and Devicefile can both be used with option dev=, but number is
+volatile (numbering changes if drives become busy).
+.TP
+.BI fifo_start_at= size
+Do not wait for full fifo but start burning as soon as the given number
+of bytes is read. This option may be helpful to bring the average throughput
+near to the maximum throughput of a drive. A large fs= and a small 
+fifo_start_at= combine a quick burn start and a large savings buffer to
+compensate for temporary lack of source data. At the beginning of burning,
+the software protection against buffer underun is as weak as the size of
+fifo_start_at= . So it is best if the drive offers hardware protection which
+is enabled automatically if not driveropts=noburnfree is given.
+.TP
+.BI \--list_ignored_options
+List all ignored cdrecord options. The "-" options cannot be used as addresses
+of track sources. No track source address may begin with a text equal to an
+option which ends by "=". The list is ended by an empty line.
+.TP
+.BI \--no_rc
+Only if used as first command line argument this option prevents reading and
+interpretation of eventual startup files. See section FILES below.
+.TP
+.BI \--prodvd_cli_compatible
+Activates behavior modifications with some DVD situations which bring cdrskin
+nearer to the behavior of cdrecord-ProDVD:
+.br
+Option -multi with unsuitable media is not an error but simply has no effect.
+.br
+Options blank=fast and blank=all deformat overwriteable DVD-RW media.
+.br
+Option blank=fast does indeed minmal blanking with DVD-RW. This may yield media
+which can only do DAO but not Incremental Streaming.
+.TP
+.BI \--single_track
+Accept only the last argument of the command line as track source address.
+.TP
+.BI tao_to_sao_tsize= size
+Set an exact fixed size for the next track to be in effect only if the track
+source cannot deliver a size prediction and no tsize= was specified and an
+exact track size prediction is demanded by the write mode.
+.br
+This was the fallback from bad old times when cdrskin was unable to burn
+in mode -tao . It came back with minimally blanked DVD-RW which allow no
+Incremental Streaming (-tao) resp. with explicitly selected write mode -sao
+for best DVD-ROM compatibility.
+.br
+If the track source delivers less bytes than announced then the missing ones
+will be filled with zeros.
+.TP 
+.BI --tell_media_space
+Prepare a recording session, do not perform it but rather inquire the
+maximum number of 2048 byte data blocks which may be written in
+the current state of media with the prepared setup. So this option disables
+recording of data. It does allow blanking, though, and will measure space
+afterwards.
+.br
+It is not mandatory to give track sources but their nature may influence
+the available capacity. So for most realistic results one may set up
+the full burn session and add --tell_media_space. But if one has to expect
+a cdrskin version prior to 0.3.3 no track source should be given in order
+not to start an involuntary burn session.
+In this case set at least -sao or -tao explicitely.
+.br
+The result gets printed to standard output. It is 0 or empty if no writing
+is possible with the given options.
+This option redirects to stderr all message output except its own result
+string and eventual output of -msinfo.
+.TP 
+.BI write_start_address= byte_offset
+Set the address on media where to start writing the track. With DVD+RW or
+DVD-RAM byte_offset must be aligned to 2 kiB blocks, but better is 32 kiB.
+With DVD-RW 32 kiB alignment is mandatory.
+.br
+Other media are not suitable for this option yet.
+.PP
+Alphabetical list of options which are only intended for very special
+situations and not for  normal use:
+.TP
+.BI \--abort_handler
+Establish default signal handling not to leave a drive in busy state
+but rather to shut it down and to wait until it has ended the final operations.
+This option is only needed for revoking eventual --ignore_signals or
+--no_abort_handler.
+.TP
+.BI \--allow_untested_media
+Enable the use of media profiles which have been implemented but not yet
+tested. Currently this applies to :
+.br
+Profile 0015h , DVD-R/DL Sequential (will not allow -multi).
+.br
+Profile 002Bh , DVD+R/DL.
+.br
+If you really test such media, then please report the outcome on
+libburn-hackers@pykix.org 
+.TP
+.BI dev_translation= <sep><from><sep><to>
+Set drive address alias. This was necessary before cdrskin-0.2.4 to manually
+translate cdrecord addresses into cdrskin addresses.
+.br
+<sep> is a single character which may not occur in the address string
+<from>. <from> is an address as expected to be given by the user via option
+dev=. <to> is the address to be used instead whenever <from> is given.
+More than one translation instruction can be given in one cdrskin run.
+.br
+E.g.: dev_translation=+ATA:1,0,0+/dev/sr1 dev_translation=+ATA:1,1,0+/dev/sr2
+.TP
+.BI \--drive_abort_on_busy
+Linux specific: Abort process if a busy drive is encountered.
+.TP
+.BI \--drive_blocking
+Linux specific: Try to wait for a busy drive to become free.
+This is not guaranteed to work with all drivers. Some need nonblocking i/o.
+.TP
+.BI \--drive_f_setlk
+Linux specific: Try to get exclusive lock on drive device file via fcntl(2).
+.TP
+.BI \--drive_not_exclusive
+Linux specific: Combine --drive_not_f_setlk and --drive_not_o_excl.
+.TP
+.BI \--drive_not_f_setlk
+Linux specific: Do not try to get exclusive lock on drive device file via
+fcntl(2).
+.TP
+.BI \--drive_not_o_excl
+Linux specific: Do not ask the operating system to prevent opening busy drives.
+Wether this leads to senseful behavior depends on operating system and kernel.
+.TP
+.BI drive_scsi_dev_family= sr | scd | sg
+Linux specific: Select a SCSI device file family to be used for drive command
+transactions. Normally this is /dev/sgN on kernel versions < 2.6 and /dev/srN
+on kernels >= 2.6 . This option allows to explicitely override that default
+in order to meet other programs at a common device file for each drive.
+On kernel 2.4 families sr and scd will find no drives.
+.br
+Device file family /dev/hdX on kernel >= 2.6 is not affected by this setting.
+.TP
+.BI \--drive_scsi_exclusive
+Linux specific:
+Try to exclusively reserve device files /dev/srN, /dev/scdM, /dev/sgK of drives.
+This would be helpful to protect against collisions with program growisofs.
+Regrettably on Linux kernel 2.4 with ide-scsi emulation this seems not to
+work. Wether it becomes helpful with new Linux systems has to be evaluated.
+.TP
+.BI \--fifo_disable
+Disable fifo despite any fs=.
+.TP
+.BI \--fifo_per_track
+Use a separate fifo for each track.
+.TP
+.BI \--fill_up_media
+Expand the last track of the session to occupy all remaining free space on
+the media.
+.br
+This option overrides option -multi. It will not fill up media if option -sao
+is given with CD media.
+.br
+.B Caution:
+This option might increase read compatibility with DVD-ROM drives but
+with some DVD recorders and media types it might also fail to produce readable
+media at all. "Your mileage may vary".
+.TP
+.BI grab_drive_and_wait= seconds
+Open the addressed drive, wait the given number of seconds, release the drive,
+and do normal work as indicated by the other options used. This option helps
+to explore the program behavior when faced with busy drives. Just start a
+second cdrskin with option --devices while grab_drive_and_wait= is still
+active.
+.TP
+.BI \--ignore_signals
+Try to ignore any signals rather than to abort the program. This is not a
+very good idea. You might end up waiting a very long time for cdrskin
+to finish.
+.TP
+.BI modesty_on_drive= <mode>[:min_percent=<num>][:max_percent=<num>]
+Mode 1 keeps the program from trying to write to the burner drive while its
+buffer is in danger to be filled by more than max_percent. If this filling is
+exceeded then the program will wait until the filling is at most min_percent.
+.br
+This can ease the load on operating system and drive controller and thus help
+with achieving better input bandwidth if disk and burner are not on independent
+controllers (like hda and hdb). Unsufficient input bandwidth is indicated by
+output "(fifo  xy%)" of option -v if xy is lower than 90 for some time.
+modesty_on_drive= might hamper output bandwidth and cause buffer underruns.
+.br
+To have max_percent larger than the burner's best actual
+buffer fill has the same effect as min_percent==max_percent. Some burners
+do not use their full buffer with all media types. Watch output "[buf xy%]"
+of option -v to get an impression of the actual buffer usage. Some burners
+are not suitable because they report buffer fill with granularity too large
+in size or time. 
+.br
+Mode 0 disables this feature. Mode -1 keeps it unchanged. Default is:
+.br
+modesty_on_drive=0:min_percent=65:max_percent=95
+.br
+Percentages are permissible in the range of 25 to 100.
+.TP
+.BI \--no_abort_handler
+On signals exit even if the drive is in busy state. This is not a very good
+idea. You might end up with a stuck drive that refuses to hand out the media.
+.TP
+.BI \--no_blank_appendable
+Refuse to blank appendable CD-RW or DVD-RW. This is a feature that was once
+builtin with libburn. No information available for what use case it was needed.
+.TP
+.BI \--no_convert_fs_adr
+Do only literal translations of dev=. This prevents cdrskin from test-opening
+device files in order to find one that matches the given dev= specifier.
+.br
+Partly Linux specific:
+Such opening is needed for Bus,Target,Lun addresses unless option
+--old_pseudo_scsi_adr is given. It is also needed to resolve device file
+addresses which are not listed with cdrskin --devices but nevertheless point
+to a usable drive. (Like /dev/sg0 using the same SCSI address as /dev/sr0.)
+.TP
+.BI \--old_pseudo_scsi_adr
+Linux specific:
+Use and report literal Bus,Target,Lun addresses rather than real SCSI and
+pseudo ATA addresses. This method is outdated and was never compatible with
+original cdrecord.
+.br

+.SS
+.B Write audio tracks to CD:
+.br
+cdrskin -v dev=ATA:1,0,0 speed=48 -sao \\
+.br
+track1.wav track2.au -audio -swab track3.raw
+.br
+.SH FILES
+If not --no_rc is given as the first argument then cdrskin attempts on
+startup to read the arguments from the following files:
+.PP
+.br
+.B /etc/default/cdrskin
+.br
+.B /etc/opt/cdrskin/rc
+.br
+.B /etc/cdrskin/cdrskin.conf
+.br
+.B $HOME/.cdrskinrc
+.br
+.PP
+The files are read in the sequence given above, but none of them is
+required for cdrskin to function properly. Each readable line is treated
+as one single argument. No extra blanks.
+A first character '#' marks a comment, empty lines are ignored.
+.SS
+.B Example content of a startup file:
+.br
+# This is the default device

-If there is sincere and well motivated interest, the cdrskin project could try

-wait for DVD support being included in libburn, though.
-A very limited and specialized cdrecord-compatibility wrapper for growisofs
-serves in my project scdbackup. It is not overly hard to make one that serves
-some very few fixed 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 for growable ISO filesystems on DVD-RAM or DVD+RW growisofs is the only
+choice, currently.

-To my knowledge, Linux kernels 2.6 do write to DVD+RW via block devices as
-they would write to a traditional tape device. Try old tape archiver
-commands with addresses like /dev/sr0 or /dev/hdc rather than /dev/mt0 .
-I have heard rumors that DVD-RW in mode "restricted overwrite" would be
-block device ready, too. My burner is not a real friend of DVD-RW and
-in an experiment the burn worked fine - but the result was not identical
-to the stream sent to the device. I had similar failure with DVD-RAM, too.

-Beware of the impact of a slow block device on overall system i/o buffering.
-It is wise to curb its input to a speed which it is able to deliver to media.
-Else your i/o dedicated RAM might buffer a big amount of stream data.
+cdrskin can offer DVD multi-session only with sequential DVD-R[W] and with
+DVD+R.
+Associated options blank=, -multi, -msinfo and -toc are available in this case.
+Thus sequential DVD-RW behave much like large CD-RW with possibly more than 99

+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.
+
+

+  http://libburnia.pykix.org/browser/libburn/trunk/libburn/ddlpa.h?format=txt

+
+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

+  ddlpa: opened siblings: /dev/scd0 /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_occupy() O_EXCL : '/dev/hdc'

+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 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: FreeBSD CAM (untested)
+
+
+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_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_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.
+
+
+Porting hints are marked by the text "PORTING:".
