            the pure SCSI knowledge has been taken from dvd+rw-tools, though.

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

+dnl    0.4.0 = 0 (also released as SONAME 4)
+dnl
+dnl Meanwhile the following schemes are maintained in parallel:
+dnl
+dnl BURN_MAJOR_VERSION , BURN_MINOR_VERSION , BURN_MICRO_VERSION 
+dnl    are three small non-negative integers which describe the evolution
+dnl    steps of the library.
+dnl    Older applications are able to use younger libraries over
+dnl    quite a long range of such steps. Some day, nevertheless,
+dnl    compatibility might get terminated, after due notice.
+dnl
+dnl SONAME (libburn.so.4)
+dnl    is a small positive integer which marks a family of compatible
+dnl    evolution steps. Libraries with a particular SONAME allow a binary
+dnl    with the same SONAME to start up. Any further compatibility check is to
+dnl    be done by own runtime means. Especially  *_version() calls in the API
+dnl    which return BURN_MAJOR_VERSION, BURN_MINOR_VERSION, BURN_MICRO_VERSION.
+dnl    See below.
+dnl
+dnl CURRENT, AGE, REVISION
+dnl    are three integers used by libtool. CURRENT is positive, the others
+dnl    non-negative. The use at runtime is not known yet. But libtool computes
+dnl    at build time  SONAME = CURRENT - AGE.
+dnl    So this is a superspace of the SONAME version space. To avoid
+dnl    ill SONAME, the value of  CURRENT must be larger than AGE.
+dnl    See also http://www.gnu.org/software/libtool/manual.html#Interfaces
+dnl
+dnl The name of the dynamic library will be libburn.so.$SONAME.$AGE.$REV .
+dnl In the terminology of this file:
+dnl    CURRENT = LT_CURRENT
+dnl    AGE     = LT_AGE
+dnl    REVISION= LT_REVISION
+dnl
+dnl Beginning with libburn-0.4.1 a rectified counting was introduced as
+dnl    CURRENT=10, REVISION=1, AGE=6
+dnl This rectification declared that version to be binary compatible up
+dnl from libburn-0.3.4.
+dnl Real compatibility was given since libburn-0.3.2.
+dnl Beware of libburn-0.2.6 which had SONAME=6 and is not binary compatible.
+dnl Applications for libburn-0.2 to libburn-0.3.1 need recompilation but no
+dnl source code changes.
+dnl
+dnl Neatly versioned stable releases meanwhile:
+dnl    0.4.2 = libburn.so.4.7.0
+dnl    0.4.4 = libburn.so.4.9.0
+dnl
+dnl So LT_CURRENT, LT_REVISION and LT_AGE get set directly here.
+dnl SONAME of the emerging library is  LT_CURRENT - LT_AGE.
+dnl The linker will do no finer checks. Especially no age range check for
+dnl the application binary. If SONAME matches, then the couple starts.
+dnl 
+dnl Therefore at run time info is provided by libburn function burn_version().
+dnl It returns the major, minor and micro revision of the library.
+dnl Before using any API feature, a program should check for age.
+dnl
+dnl The variables BURN_*_VERSION are mere copies for informing libtool.
+dnl The true values which get issued and should be compared are macros
+dnl defined in libburn/libburn.h .
+dnl
+dnl Normally one can allow a program to run with a library which passed the
+dnl linker SONAME test and which is not older than the library it was
+dnl developed for. Library2 is younger than library1 if:
+dnl   major2>major1 || (major2==major1 &&
+dnl                     (minor2>minor1 || (minor2==minor1 && micro2 > micro1)))
+dnl
+dnl If BURN_*_VERSION changes, be sure to change AC_INIT above to match.

+library. This is to allow runtime libraries which are
+young enough for the application but too old for

+at the cost of excluding some older libraries.

+    See below MISHAP for what xorriso would need instead of this kind of SORRY
+    and generates for itself in case of libisofs image generation.
+
+    E.g.: A pattern yields no result.
+          A speed setting cannot be made.
+          A libisofs input file is inaccessible during image generation.
+
+    After SORRY a function should try to go on if that makes any sense
+    and if no threshold prescribes abort on SORRY. The function should
+    nevertheless indicate some failure in its return value. 
+    It should - but it does not have to.
