Conky is a light-weight system monitor that can be easily customized
with lua scripts. This adds a module that can be directly loaded via
conky.conf and be used to display information about current usage of
boards controlled by cdba.
Put the script under a new directory: contrib/. It'll be used to store
misc files that don't fit anywhere else.
