The main documentation is availiable via --help and near the top of any bash
script files which sit next to this file.

The script file can be stripped of the last line and used as a function
instead of a script.

Patches, bugs, and any feedback is very welcome via gitorious or email to
Ian Kelling <ian@iankelling.org>.

This program is also part of a collection of programs,
https://gitorious.org/bash-programs-by-ian, which are unrelated except
having the same author and being being bash programs.
