trac-darcs can be used as a separate plugin to trac without requiring any changes to trac itself. The patches in the source repo are for integrating trac-darcs *into* the trac code itself.

It seems like that would start taking up a lot of disk space. Unfortunately, in darcs, there's no direct and simple way to access a older version of a file. Right now 'darcs annotate + ann2ascii' is used to fetch the data. Since this is slow, caching is a must. This isn't too bad because only those verions of files, which are accessed thru the webui, are cached. The cache is stored in the 'darcs_cache' table in the trac db, and this can be cleared if it gets too big. [sreeram;]
