freeware to document your IT infrastructure for unix

I just started using this good free software that lets you document your entire IT infrastructure. It's called Auditor Lite or Documentor for Unix and in my opinion it's the best software out there and the fact that it is free is even better. Just thought I would let you guys know if you want to give it a shot it's working out great for us.

Yeah idea of sharing a valuable software was great, but you should post it in whats on your mind forum not here, maybe moderators can move it there.
