Needed: functionality of mkisofs command

[Richard Owlett <rowlett@cloud85.net>]

I wish to use ISO files as archives.

Multiple references suggest command of form:
> $ mkisofs –o backup.iso /home/tin/Documents/backup

Debian does not have "mkisofs".

The manpages for xorriso and xorrisofs say they are suitable.

BUT give no example. I got lost attempting to follow the manpages.

Help please.
