+===== xorriso not found ===== #xorriso_not_found
+
+This message is issued by programs which use [wiki:Xorriso xorriso] for
+producing ISO 9660 filesystem images. E.g. by GRUB2's grub-mkrescue.
+
+Executable xorriso binaries are normally contained in software packages
+named "libisoburn" or "xorriso".
+
+If your operating system does not offer such a package, then consider
+to get the [http://www.gnu.org/software/xorriso#download GNU xorriso]
+source tarball. For instructions read in its
+[http://www.gnu.org/software/xorriso/README_xorriso README file]
+the paragraph "Compilation, First Glimpse, Installation".
+With grub-mkrescue it is possible to use the resulting binary without further
+installation. Just submit its absolute path with option --xorriso=. E.g.:
+{{{
+  grub-mkrescue --xorriso=$HOME/xorriso-1.3.8/xorriso/xorriso -o output.iso
+}}}
+
+===== xorriso tutorial ===== #xorriso_tutorial
+
+There is not much more than the
+[http://www.gnu.org/software/xorriso/man_1_xorriso.html#EXAMPLES man xorriso examples].
+
+Volunteers are wanted who make a collection of use cases, ask at bug-xorriso
+for xorriso instructions to fulfill the needs, and describe both in a
+user-readable manner.
+
+Up to then, the GUI demo [http://svn.libburnia-project.org/libisoburn/trunk/frontend/README-tcltk xorriso-tcltk]
+([http://www.gnu.org/software/xorriso/xorriso-tcltk-screen.gif screenshot])
+may serve as interactive exploration tool. It needs xorriso >= 1.2.4, Tcl,
+Tk >= 8.4, optionally Tcl / Tk package "BWidget".
+{{{
+  xorriso-tcltk --script_log_file -
+}}}
+starts the GUI and will log the essential xorriso commands in the start
+terminal. I.e. click on "Scan for drives" and learn that this operation
+is triggered by xorriso command "-devices".
+
+Click the rightmost mouse button while being over any of the GUI elements
+in order to get the particular help text for that element.
+Have [http://www.gnu.org/software/xorriso/man_1_xorriso.html man xorriso]
+ready to learn what the particular commands mean.
+
+
+===== xorriso create ISO image ===== #xorriso_create_iso
+
+{{{
+  xorriso -outdev $HOME/result.iso \
+          -map /home/me/sounds /sounds \
+          -map /home/me/pictures /pictures
+}}}
+This points the output to file $HOME/result.iso, which should not yet exist.
+Then it maps disk directory /home/me/sounds to ISO directory /sounds,
+and /home/me/pictures to /pictures.
+At program end, the ISO image gets produced and the contents of the
+two directory trees gets copied into the ISO.
+
+If you have experience with program mkisofs, you may also use its
+emulation by xorriso:
+{{{
+  xorriso -as mkisofs \
+          -o $HOME/result.iso \
+          -graft-points \
+          /sounds=/home/me/sounds \
+          /pictures=/home/me/pictures
+}}}
+
+See [http://www.gnu.org/software/xorriso/man_1_xorriso.html man xorriso]
+for xorriso native commands.
+
+See [http://www.gnu.org/software/xorriso/man_1_xorrisofs.html man xorriso]
+for its mkisofs emulation.
