\-c <dir> [name] : Create xiso from file(s) starting in (local or remote) <dir>.  If the [name] parameter is specified, the xiso will be created with the (path and) name given, otherwise the xiso will be created in the current directory with the name <dir>.iso.  The -c option may be specified multiple times to create multiple xiso images.

\-x : Extract xiso(s) (the default mode if none is given). If no directory is specified with -d, a directory with the name of the xiso (minus the .iso portion) will be created in the current directory and the xiso will be expanded there.
