Reusable module repository

Hi all,

I hope this is considered on-topic, seeing as how it is a programming 
related problem.  Just wondering if anyone has any recommendations for a 
system to track and document modules and service programs which are 
intended to be reused internally.  I've poked around Sourceforge a bit and 
I'm having trouble finding anything of this ilk.  I'm not even sure 
exactly what we would need to track, but the sort of thing that comes to 
mind are name, description, files used, documentation for each procedure 
(perhaps through some sort of Javadoc type system, but for RPG), 
references to some programs that use the module (for usage example 
purposes), etc.  Another key feature would be a good search function - I 
can't reuse something if I can't find it.

Does this sort of thing exist?  Any suggestions would be appreciated,
Adam
