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

+
+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 MB).
+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 MB. 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.

+.PP
+.\" 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.
+.PP
+.B General information paragraphs:
+.br
+Track recording model
+.br
+Write mode selection
+.br
+Recordable CD Media
+.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.
+.br
+Currently DVD+R are always kept appendable regardless wether -multi is given
+or not. This might change in future so it is strongly advised to already now
+use
+.B -multi
+whenever the disc shall be kept appendable.
+.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/sg0\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/sr0).

+.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:

+.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 MB 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 MB.
+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 guarantee that this will work with a particular combination
+of drive, media, and write mode. Blanking is prevented reliably, though.
+.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
+.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 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 kB 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.
+.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
+Example. Retrieve an afio archive from track number 2:
+.br
+tracknumber=2
+.br
+lba=$(cdrskin dev=/dev/cdrom -toc 2>&1 | \\
+.br

+.br
+tail +"$tracknumber" | head -1 | \\
+.br
+awk '{ print $4}' )
+.br
+dd if=/dev/cdrom bs=2048 skip="$lba" | \\
+.br
+afio -t - | less
+.RE
+.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 \--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 KB blocks, but better is 32 kB.
+With DVD-RW 32 kB 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/sg1 dev_translation=+ATA:1,1,0+/dev/sg2
+.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_not_exclusive
+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_exclusive
+Linux specific:
+Try to exclusively reserve device files /dev/srN, /dev/scdM, /dev/stK of drive.
+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 \--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/sr0 using the same SCSI address as /dev/sg0.)
+.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

-- "test"   is a collection of application gestures and examples given by the
-           authors of the library features. The main API example of libburn
-           is named test/libburner.c .
-           Explore these examples if you look for inspiration.
-
-We plan to be a responsive upstream. Bear with us.
-
-
-   @section using Using the libraries
-
-Our build system is based on autotools.
-User experience tells us that you will need at least autotools version 1.7.
-
-To build libburn and its subprojects it should be sufficient to go into
-its toplevel directory and execute
-
--  ./bootstrap  (needed if you downloaded from SVN)
-
--  ./configure
-
--  make
-
-To make the libraries accessible for running resp. developing applications 
-
--  make install
-
-Both libraries are written in C language and get built by autotools.
-Thus we expect them to be useable by a wide range of Linux-implemented
-languages and development tools.
-
-
-@section libburner Libburner
-
-libburner is a minimal demo application for the library libburn 
-(see: libburn/libburn.h) as provided on  http://libburn.pykix.org .
-It can list the available devices, can blank a CD-RW and
-can burn to CD-R or CD-RW.
-
-It's main purpose, nevertheless, is to show you how to use libburn and also
-to serve the libburn team as reference application. libburner does indeed
-define the standard way how above three gestures can be implemented and
-stay upward compatible for a good while.
-
-   @subsection libburner-help Libburner --help
-<pre>
-Usage: test/libburner
-       [--drive <address>|<driveno>|"-"]
-       [--verbose <level>] [--blank_fast|--blank_full]
-       [--burn_for_real|--try_to_simulate] [--stdin_size <bytes>]
-       [<imagefile>|"-"]
-Examples
-A bus scan (needs rw-permissions to see a drive):
-  test/libburner --drive -
-Burn a file to drive chosen by number:
-  test/libburner --drive 0 --burn_for_real my_image_file
-Burn a file to drive chosen by persistent address:
-  test/libburner --drive /dev/hdc --burn_for_real my_image_file
-Blank a used CD-RW (is combinable with burning in one run):
-  test/libburner --drive 0 --blank_fast
-Burn a compressed afio archive on-the-fly, pad up to 700 MB:
-  ( cd my_directory ; find . -print | afio -oZ - ) | \
-  test/libburner --drive /dev/hdc --burn_for_real --stdin_size 734003200  -
-To be read from *not mounted* CD via:
-   afio -tvZ /dev/hdc
-Program tar would need a clean EOF which our padded CD cannot deliver.
-</pre>
