This has been said in one of the earlier responses, but I thought it was
worth repeating: darcs has a notion of context files which can be used to
retrieve exactly another version of a repository with darcs get
You can generate such files by invoking darcs changes --context. For
that matter, patch bundles (as created by darcs send) can also be used
as context files. It's sometimes quite handy to do something like darcs
get --context foo.dpatch to retrieve exactly the version of the
repository a patch bundle was meant to apply to.
This is one of the little known features of darcs, and should probably
appear in some kind of darcs tips series of blog articles :-)
