OT: Open Source version of MS Project?

["Mark Haney" <mark.haney@xxxxxxxxxxxxxxxxxxx>]

Kind of off topic, but since I work primarily in a Windoze shop, and I'm  
trying to get Linux in the door here I will need compatible tools for what  
we use here.  Does any know of an open source Project Management tool like  
MS Project?  It doesn't necessarily have to be Project compatible, just  
have similar functionality.  Free would be good, but not a requirement  
either.
