Revision #1:

• Instead of allowing you to run the script anywhere and potentially batch retag a bunch of stuff wrongly, script now requires you to run it from the parent directory of Beriah and only goes ahead if it has successfully cd'ed into a directory with a sensible sounding name.

Revision #2:

• 'Field' separator, not 'file' separator. Fine.
