As Markus said, is there native support in makepkg for VCSs (i.e. git,
bzr, hg, darcs, svn,...) or is this just a discussion regarding a
feature request?
If it's the former, how come it's not documented in the wiki? It would
simplify my git PKGBUILDS greatly.
If it's the latter, then I'm very interested, and am willing to
provide any assistance needed - just point me to the code.
