addresses get compared whether they have counterparts below the other address
and whether both counterparts match.
.TP
.B osirrox restore options:
.PP
Normally xorriso only writes to disk files which were given as stdio:
pseudo-drives or as log files.
But its alter ego, osirrox, is able to extract file objects
from ISO images and to create, overwrite, or delete file objects on disk.
.TP
\fB\-osirrox\fR "on"|"off"
Setting "off" disables disk filesystem manipulations. This is the default
unless the program was started with leafname "osirrox". Elsewise
the capability to restore files can be enabled explicitly by -osirrox "on".
.TP
\fB\-cpx\fR iso_rr_path [***] disk_path
Extract regular files from the ISO image and store them under the address given
by disk_path. If more then one iso_rr_path is given then disk_path must be
a directory or non-existent. In the latter case it gets created and the
extracted files get installed in it with the same leafnames.
.br
Missing directory components in disk_path will get created, if possible.
.TP
.B Command compatibility emulations:
.PP
Writing of ISO 9660 on CD is traditionally done by program mkisofs
