    smgl.install/enchant: new, cache installer script
    
    New script to support the installation of optional spell caches. The
    script supports installing via /tmp/opt-spells, which can be set up by
    alchemy (yet to be committed), or by handling caches one-off (which can
    be looped to handle directories of caches). This is a powerful new
    edition to the ISO installer, because not only does this allow for the
    installation of optional spell caches provided on the ISO, it also
    allows for one to install any caches from any medium that the ISO can
    reach (and with net modules and net tools on the ISO, it's possible to
    link up with nfs partitions).

+Usage: $(basename $0) [-h] [-d /path/to/target] [CACHE1 [CACHE2..]]
+
+Installs caches to the target system (defined as /mnt/root if not
+specified). The caches installed can either be specified on the
+command-line as arguments, or they will be taken from information
+provided via /tmp/opt-spells. Note: if you are providing caches on the
+command-line, you must give the full cache filename, and caches with
+an extension of .tar.bz2 are expected.
+
+Options:
+  -d  Path to target directory. Defaults to /mnt/root.
+
+       -h  Shows this help information
