+.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.

 Writing of ISO 9660 on CD is traditionally done by program mkisofs
