# look in the path defined below for a script matching that command name and run it.
#
# e.g. ?uptime would look in "/usr/share/irccat/" (the default) for any script called
# "uptime", with any extension. It would happily run both uptime.sh and uptime.py, or
# a script in whatever language you like. Command names are limited to [0-9a-z].
