+===============================================================================
+* Bug fix: -boot_image and -append_partition were not perceived as image
+           manipulation which makes production of an ISO image worthwhile.
+           Thanks Cameron Seader.
+* Bug fix: -outdev holding an ISO filesystem could get attached wrong start LBA
+* Bug fix: Command -load "volid" did not work with constant search text
+* Bug fix: Command -truncate_overwritable on ISO image without MD5 caused
+           double free of memory
+* Bug fix: -boot_image "any" "replay" failed after the legacy BIOS boot image
+           file was replaced by -map. Thanks Brian C. Lane.
+* Bug fix: -boot_image system_area=/dev/zero preserved system area of
+           loaded ISO
+* Bug fix: Size assessment of ISO images smaller than 32 KiB yielded
+           random values
+* New -append_partition pseudo partition_number "all" and
+  pseudo type_code "revoke"
+* New bit1 with API call Xorriso_change_is_pending() issues a note if
+  return is 0 and indev and outdev point to different drives
+* New API calls isoburn_toc_disc_get_sectors_v2,
+  isoburn_toc_session_get_sectors_v2, isoburn_toc_track_get_emul_v2
+* New API calls isoburn_read_iso_head_v2(), isoburn_get_mount_params_v2()
+* New API calls isoburn_igopt_get_effective_lba_v2(),
+  isoburn_igopt_get_data_start_v2()

+* New API call isoburn_prepare_blind_grow_v2()
+* New -as mkisofs options -cut_out and -hide_iso_path
+* Improved handling of hidden boot images in -boot_image cmd/as_mkisofs/replay

+* Bug fix: False -status failure with -boot_image --interval:appended_partition
+* Bug fix: -no_rc prevented pre-scanning of arguments for stdio output and
+           others. Introduced by mistake in a62f6af5, 2011.10.18.162119.
+* Bug fix: -not_leaf and -not_paths were not applied to -extract and alike
+* Bug fix: -report_system_area cmd misperceived -part_like_isohybrid with
+           -isohybrid-gpt-basdat
+* Bug fix: -report_system_area cmd misperceived combination of isohybrid and
+           appended partition in GPT
+* Bug fix: -as mkisofs option -part_like_isohybrid did not cause a MBR
+           partition table if the partitions are data files in the ISO
+           rather than appended
+* Bug fix: Split file directories (-split_size) were created with wrong
+           permissions
+* Bug fix: libisofs did not mark clones of imported files as imported.
+           This could cause that original and clone occupy data storage
+           in the newly written session. Thanks to Ivan Shmakov.
+* Bug fix: Partition offset was preserved from -indev rather than from -outdev
+* Bug fix: libisofs could misrepresent Rock Ridge information if many
+           symbolic links or AAIP data were recorded in a directory
+* Bug fix: Data files named /boot.catalog or ./boot.cat could be left out of
+           the emerging ISO if the boot catalog was set to be hidden
+* Bug fix: -toc reported wrong track LBA with overwritable media with
+           unrecognized content (pseudo-closed)
+* Bug fix: -find test -has_xattr matched "isofs." attributes
+           in -xattr mode "any"
+* New API call isoburn_assess_written_features()
+* New API calls isoburn_igopt_set_max_ce_entries(),
+  isoburn_igopt_get_max_ce_entries()
+* New flag bit12 with isoburn_read_iso_head():
+  Read even if start of multi-session emulation is damaged

+.SH NAME
+merge_debian_isos \-  Program to merge multiple debian\-cd ISO images
+.SH SYNOPSIS
+.B merge_debian_isos
+result_iso mount_template iso1 iso2 [... isoN]
+.br
+.SH DESCRIPTION
+.PP
+\fBmerge_debian_isos\fR
+mounts by \fBsudo\fR the ISO 9660 images iso1 to isoN at directories
+mount_template1 to mount_templateN, if not already mounted that way.
+Then the Debian pools and package lists get merged and a new
+ISO 9660 image result_iso is produced by a run of \fBxorriso\fR.
+If iso1 is bootable then
+the new image will be bootable by the same means.
+.br
+.PP
+The file depicted by result_iso must not yet exist or has to be a
+device which is acceptable for Linux\-specific helper script
+\fBxorriso\-dd\-target\fR. If xorriso\-dd\-target agrees and the user
+confirms by input "yes" then xorriso will be run under sudo.
+.br
+Exempted from this evaluation are addresses which begin by "mmc:"
+for an optical drive on Linux, BSDs, Solaris, or by "stdio:/dev/"
+for which the user takes full and dangerous responsibility.
+.br
+Special result_iso path \fBxorriso\-dd\-target\-plug\-test\fR determines
+on systems with Linux kernel the target USB stick by a dialog around plugging
+it in.
+xorriso will be run under sudo, if xorriso\-dd\-target agrees and
+the user confirms by input "yes".
+.br
+.PP
+At least the parent directory of argument \fBmount_template\fR must already
+exist or has to be given by a plain name without "/" so that it can be
+created in the current directory. (I.e. without even "./".)
+.br
+All arguments must be single words without using quotation marks.
+None of the isoN must be equal to another isoM.
+.br
+.PP
+This script creates and finally removes the following temporary tree
+and files which must not yet exist in the current working directory:
+  ./merged_dists , ./merged_md5sum.txt , ./merged_REAMDE.txt
+  ./temp_file
+.br
+Further it creates and finally removes directories mount_template*
+if they are needed and do not exist when the script starts. If the
+parent directory in the mount_template path does not exist and
+its path contains no "/" then it gets created and finally removed.
+The script depends on the following programs:
+.br
+  awk, basename, cat, chmod, cp, date, dirname, expr, fgrep, grep,
+  gunzip, gzip, head, ls, md5sum, mkdir, mount, mv, rm, rmdir,
+  sed, sh, sha256sum, sort, stat, sudo, umount, uniq, xorriso
+.br
+With device writing involving helper script xorriso\-dd\-target:
+.br
+  dd, Linux kernel, lsblk, sleep, tr, uname, wc, whoami,
+  xorriso\-dd\-target
+.br
+Recommended are: sha1sum, sha512sum
+
+.SS
+.br
+.SH OPTIONS
+.br
+.PP
+merge_debian_isos has no command line options besides the input words described
+above, but it reacts on some environment variables.
+.br
+See section ENVIRONMENT.
+.br
+.PP
+If less than 4 arguments are given, the script will print its help text to
+standard error and exit with non\-zero value, indicating failure.
+.SS
+.SH EXAMPLES
+.SS
+.B Overview of examples:
+Merge DVD images 1 to 5
+.br
+Use GNU xorriso instead of installed xorriso
+.br
+Write result directly to an optical drive
+.br
+Write result directly and safely to USB stick (Linux only)
+.br
+Write result directly and unsafely to USB stick
+.SS
+.B Merge DVD images 1 to 5
+The resulting image will be named "merged.iso".
+.br
+Directory ./merge_mount/ will be created if not yet existing.
+.br
+
+merge_debian_isos merged.iso merge_mount/iso \\
+                  debian\-11.2.0\-amd64\-DVD\-[12345].iso
+
+.br
+Expect to see some harmless warnings like
+.br
+
+xorriso : WARNING : \-volid text does not comply to ISO 9660 / ECMA 119 rules
+
+libisofs: WARNING : Cannot add /debian to Joliet tree. Symlinks can only be added to a Rock Ridge tree.
+
+libisofs: WARNING : Image size exceeds 1024 cylinders. Cannot align partition.
+
+.SS
+.B Use GNU xorriso instead of installed xorriso
+merge_debian_isos will refuse to work if the installed version of xorriso
+is older than 1.4.2. In this case consider to download and compile the
+GNU xorriso tarball from
+.br
+  https://www.gnu.org/software/xorriso/#download
+.br
+You may use it without installing it after compilation and thus without
+disturbing your system's package management. Assumed that you unpacked the
+xorriso\-1.5.6 tarball in your $HOME directory and have successfully compiled
+it, do:
+.br
+
+export XORRISO="$HOME"/xorriso\-1.5.6/xorriso/xorriso
+.br
+
+merge_debian_isos merged.iso merge_mount/iso \\
+                  debian\-11.2.0\-amd64\-DVD\-[12345].iso
+
+.SS
+.B Write result directly to an optical drive
+xorriso is able to burn optical media on GNU/Linux (/dev/sr*),
+Solaris (/dev/rdsk/*) , FreeBSD (/dev/cd*) , NetBSD (/dev/rcd*),
+and OpenBSD (/dev/rcd*). Get a list of available optical drive devices by:
+.br
+
+xorriso \-devices
+.br
+
+It might be that you need superuser powers for this and then have to enable
+access to the device file for the user who runs merge_debian_isos.
+.br
+
+In order to directly write the merged ISO image to an optical medium,
+use the desired device file path with prefix "mmc:":
+.br
+
+merge_debian_isos mmc:/dev/sr0 merge_mount/iso \\
+                  debian\-11.2.0\-amd64\-DVD\-[12345].iso
+
+.SS
+.B Write result directly and safely to USB stick (Linux only)
+The Linux\-specific script \fBxorriso\-dd\-target\fR evaluates device files
+whether they and their content look unimportant enough for being overwritten
+by an image file.
+.br
+This mainly means that the storage device is attached to USB and contains
+no filesystems which are not of type FAT or ISO 9660.
+.br
+You may get xorriso\-dd\-target by:
+.br
+
+wget \\
+  https://dev.lovelyhq.com/libburnia/libisoburn/raw/master/xorriso\-dd\-target/xorriso\-dd\-target
+chmod u+x xorriso\-dd\-target
+.br
+
+Consider to also download xorriso\-dd\-target.sig and to verify the script by
+.br
+
+gpg \-\-verify xorriso\-dd\-target.sig xorriso\-dd\-target
+.br
+
+Announce the storage location of the downloaded xorriso\-dd\-target:
+.br
+
+export XORRISO_DD_TARGET_PATH="$(pwd)"
+.br
+
+The prepared use case in merge_debian_isos uses the xorriso\-dd\-target
+option \-plug_test under \fBsudo\fR, which asks the user for first having
+the desired USB stick unplugged so that the unwanted devices can get
+registered. Then it asks the user to plug in the USB stick, so that it gets
+recognized as desired target.
+.br
+xorriso\-dd\-target evaluates the content and decides whether it looks
+disposable enough. If so, then it allows merge_debian_isos to write its
+result to the device.
+.br
+
+merge_debian_isos xorriso\-dd\-target\-plug\-test merge_mount/iso \\
+                  debian\-11.2.0\-amd64\-DVD\-[12345].iso
+
+.SS
+.B Write result directly and unsafely to USB stick
+On operating systems other than GNU/Linux or with storage devices not
+acceptable to xorriso\-dd\-target it is possible to remove all safety
+precautions beyond those of xorriso, which can be overcome by "blanking"
+the device. 
+.br
+So after due evaluation of the device situation and on your very own risk
+you may use the device path prefix "stdio:", possibly with superuser powers: 
+.br
+
+xorriso \-outdev stdio:/dev/sdd \-blank as_needed
+
+merge_debian_isos stdio:/dev/sdd merge_mount/iso \\
+                  debian\-11.2.0\-amd64\-DVD\-[12345].iso
+
+For details about "stdio:" and pseudo\-blanking non\-optical devices read
+man xorriso.
+.br
+The xorriso run in merge_debian_isos ignores locally defined xorriso startup
+files (by command \-no_rc). 
+.SH FILES
+For now, no files are defined for configuration.
+.SH ENVIRONMENT
+The following environment variables influence the program behavior:
+.br
+Exported non\-empty variable MERGE_DATE enforces a particular
+date string in the text which gets prepended to /README.txt .
+.br
+Exported non\-empty variable MERGE_FOR_DIST enforces the use of a
+particular directory in /dists of iso1. Normally only one
+such directory is found and thus no need to set MERGE_FOR_DIST.
+.br
+Exported non\-empty variable MERGE_KEEP_ISO prevents the removal
+of result_iso after xorriso indicated failure of production.
+.br
+Exported non\-empty variable XORRISO gives the path to a xorriso binary,
+which will be used instead of the system\-wide installed xorriso binary.
+This may be needed if installed xorriso is older than 1.4.2. 
+.br
+If XORRISO is set to "dummy" then no new ISO will emerge.
+.br
+Exported non\-empty variable XORRISO_DD_TARGET_PATH names the
+directory where to find xorriso\-dd\-target, which evaluates the
+suitability of result_iso devices or does the plug\-test dialog.

+@c man .SH SYNOPSIS
+@c man .B merge_debian_isos
+@c man result_iso mount_template iso1 iso2 [... isoN]
+@c man .br
+@c man .SH DESCRIPTION
+@c man .PP
+@command{merge_debian_isos}
+mounts by @strong{sudo} the ISO 9660 images iso1 to isoN at directories
+mount_template1 to mount_templateN, if not already mounted that way.
+Then the Debian pools and package lists get merged and a new
+ISO 9660 image result_iso is produced by a run of @strong{xorriso}.
+If iso1 is bootable then
+the new image will be bootable by the same means.
+@*
+@sp 1
+@c man .PP
+The file depicted by result_iso must not yet exist or has to be a
+device which is acceptable for Linux-specific helper script
+@strong{xorriso-dd-target}. If xorriso-dd-target agrees and the user
+confirms by input "yes" then xorriso will be run under sudo.
+@*
+Exempted from this evaluation are addresses which begin by "mmc:"
+for an optical drive on Linux, BSDs, Solaris, or by "stdio:/dev/"
+for which the user takes full and dangerous responsibility.
+@*
+Special result_iso path @strong{xorriso-dd-target-plug-test} determines
+on systems with Linux kernel the target USB stick by a dialog around plugging
+it in.
+xorriso will be run under sudo, if xorriso-dd-target agrees and
+the user confirms by input "yes".
+@*
+@sp 1
+@c man .PP
+At least the parent directory of argument @strong{mount_template} must already
+exist or has to be given by a plain name without "/" so that it can be
+created in the current directory. (I.e. without even "./".)
+@*
+All arguments must be single words without using quotation marks.
+None of the isoN must be equal to another isoM.
+@*
+@sp 1
+@c man .PP
+This script creates and finally removes the following temporary tree
+and files which must not yet exist in the current working directory:
+  ./merged_dists , ./merged_md5sum.txt , ./merged_REAMDE.txt
+  ./temp_file
+@*
+Further it creates and finally removes directories mount_template*
+if they are needed and do not exist when the script starts. If the
+parent directory in the mount_template path does not exist and
+its path contains no "/" then it gets created and finally removed.
+The script depends on the following programs:
+@*
+  awk, basename, cat, chmod, cp, date, dirname, expr, fgrep, grep,
+  gunzip, gzip, head, ls, md5sum, mkdir, mount, mv, rm, rmdir,
+  sed, sh, sha256sum, sort, stat, sudo, umount, uniq, xorriso
+@*
+With device writing involving helper script xorriso-dd-target:
+@*
+  dd, Linux kernel, lsblk, sleep, tr, uname, wc, whoami,
+  xorriso-dd-target
+@*
+Recommended are: sha1sum, sha512sum

+@section Use GNU xorriso instead of installed xorriso
+merge_debian_isos will refuse to work if the installed version of xorriso
+is older than 1.4.2. In this case consider to download and compile the
+GNU xorriso tarball from
+@*
+  https://www.gnu.org/software/xorriso/#download
+@*
+You may use it without installing it after compilation and thus without
+disturbing your system's package management. Assumed that you unpacked the
+xorriso-1.5.6 tarball in your $HOME directory and have successfully compiled
+it, do:
+@*
+@sp 1
+
+export XORRISO="$HOME"/xorriso-1.5.6/xorriso/xorriso

+
+@c man .SS
+@c man .B Write result directly to an optical drive
+@node ExOptical, ExDdTarget, ExXorriso, Examples
+@section Write result directly to an optical drive
+xorriso is able to burn optical media on GNU/Linux (/dev/sr*),
+Solaris (/dev/rdsk/*) , FreeBSD (/dev/cd*) , NetBSD (/dev/rcd*),
+and OpenBSD (/dev/rcd*). Get a list of available optical drive devices by:
+@*
+@sp 1
+
+xorriso -devices
+@*
+@sp 1
+
+It might be that you need superuser powers for this and then have to enable
+access to the device file for the user who runs merge_debian_isos.
+@*
+@sp 1
+
+In order to directly write the merged ISO image to an optical medium,
+use the desired device file path with prefix "mmc:":
+@*
+@sp 1
+
+merge_debian_isos mmc:/dev/sr0 merge_mount/iso \
+                  debian-11.2.0-amd64-DVD-[12345].iso
+
+@c man .SS
+@c man .B Write result directly and safely to USB stick (Linux only)
+@node ExDdTarget, ExStdio, ExOptical, Examples
+@section Write result directly and safely to USB stick (Linux only)
+The Linux-specific script @strong{xorriso-dd-target} evaluates device files
+whether they and their content look unimportant enough for being overwritten
+by an image file.
+@*
+This mainly means that the storage device is attached to USB and contains
+no filesystems which are not of type FAT or ISO 9660.
+@*
+You may get xorriso-dd-target by:
+@*
+@sp 1
+
+wget \
+  https://dev.lovelyhq.com/libburnia/libisoburn/raw/master/xorriso-dd-target/xorriso-dd-target
+chmod u+x xorriso-dd-target
+@*
+@sp 1
+
+Consider to also download xorriso-dd-target.sig and to verify the script by
+@*
+@sp 1
+
+gpg --verify xorriso-dd-target.sig xorriso-dd-target
+@*
+@sp 1
+
+Announce the storage location of the downloaded xorriso-dd-target:
+@*
+@sp 1
+
+export XORRISO_DD_TARGET_PATH="$(pwd)"
+@*
+@sp 1
+
+The prepared use case in merge_debian_isos uses the xorriso-dd-target
+option -plug_test under @strong{sudo}, which asks the user for first having
+the desired USB stick unplugged so that the unwanted devices can get
+registered. Then it asks the user to plug in the USB stick, so that it gets
+recognized as desired target.
+@*
+xorriso-dd-target evaluates the content and decides whether it looks
+disposable enough. If so, then it allows merge_debian_isos to write its
+result to the device.
+@*
+@sp 1
+
+merge_debian_isos xorriso-dd-target-plug-test merge_mount/iso \
+                  debian-11.2.0-amd64-DVD-[12345].iso
+
+@c man .SS
+@c man .B Write result directly and unsafely to USB stick
+@node ExStdio, Files, ExDdTarget, Examples
+@section Write result directly and unsafely to USB stick
+On operating systems other than GNU/Linux or with storage devices not
+acceptable to xorriso-dd-target it is possible to remove all safety
+precautions beyond those of xorriso, which can be overcome by "blanking"
+the device. 
+@*
+So after due evaluation of the device situation and on your very own risk
+you may use the device path prefix "stdio:", possibly with superuser powers: 
+@*
+@sp 1
+
+xorriso -outdev stdio:/dev/sdd -blank as_needed
+
+merge_debian_isos stdio:/dev/sdd merge_mount/iso \
+                  debian-11.2.0-amd64-DVD-[12345].iso
+
+For details about "stdio:" and pseudo-blanking non-optical devices read
+man xorriso.
+@*
+The xorriso run in merge_debian_isos ignores locally defined xorriso startup
+files (by command -no_rc).

+@chapter Files
+@c man .SH FILES
+For now, no files are defined for configuration.
+@c man .SH ENVIRONMENT
+@node Environ, Seealso, Files, Top
+@chapter Environ
+The following environment variables influence the program behavior:
+@*
+Exported non-empty variable MERGE_DATE enforces a particular
+date string in the text which gets prepended to /README.txt .
+@*
+Exported non-empty variable MERGE_FOR_DIST enforces the use of a
+particular directory in /dists of iso1. Normally only one
+such directory is found and thus no need to set MERGE_FOR_DIST.
+@*
+Exported non-empty variable MERGE_KEEP_ISO prevents the removal
+of result_iso after xorriso indicated failure of production.
+@*
+Exported non-empty variable XORRISO gives the path to a xorriso binary,
+which will be used instead of the system-wide installed xorriso binary.
+This may be needed if installed xorriso is older than 1.4.2. 
+@*
+If XORRISO is set to "dummy" then no new ISO will emerge.
+@*
+Exported non-empty variable XORRISO_DD_TARGET_PATH names the
+directory where to find xorriso-dd-target, which evaluates the
+suitability of result_iso devices or does the plug-test dialog.
