+ The first parameter is either the full path to a Slackware package,
+ or else a directory.
+ If a packagename is supplied as first parameter, it will be installed
+ into a temporary directory using Slackware's "installpkg".
+ The content of the temporary directory will be squashed into a module
+ by the "squashfs" program.
+ If a directoryname is supplied, its content will be squashed into
+ a module by the "squashfs" program.
+ The second parameter is the full pathname of the output module
+ which will be created.
