With parameter @strong{help} print a text which explains the meaning of the
lines put out by "plain".

Parameter @strong{cmd} tries to print the @strong{xorriso} commands which are
necessary to produce the found El Torito equipment and System Area.
The intended use case is modification of the filesystem by having -indev
and -outdev pointing to different images or drives.
The result might be insufficient, if the found equipment cannot be
produced by xorriso.

Parameter @strong{as_mkisofs} tries to print the @strong{xorriso -as mkisofs}
options, which are necessary to produce the found equipment.
The intended use case is to use the mounted filesystem as input tree
together with the printed options. In some cases (e.g. -isohybrid-mbr) it
might be necessary to extract data from ISO to hard disk in order to
use the hard disk files as arguments of -as mkisofs options.
