Rails - Jan 2006 - Looking for a simple Scheduler Gem

I have to implement a scheduler for a conference room.  I know I can 
probably do a fairly good job writing one myself, but in the short term if a 
good one already exists I''d like to at least consider it.  I
didn''t find
anything on rubygems.   Does anyone know of a simple resource scheduler?

Thanks,

Gary H.
