Comment (by kolmodin):

 I'd like a tool that downloads the scm version of a cabal package. very
 simple yet I'd find it much useful.

 {{{
 cabal-source get zlib
 }}}
 should run darcs and give me the zlib repo in the current dir. Nice...

 About knowing which kind of repo it is, lets have a look what other tools
 does.
 Layman is an application to help the user get and update his Gentoo
 overlays (extra stuff not covered in portage).
 It uses a description file, http://www.gentoo.org/proj/en/overlays/layman-
 global.txt .
 A short snippet from the xml:
 {{{
  type = "darcs"
  src  = "http://www.haskell.org/~gentoo/gentoo-haskell/"
 }}}

 It mentions both the type of scm, and the location.

 Another alternative would be to just write an URI, possibly combining the
 tool and the source location:
 {{{
 darcs+http://www.haskell.org/~gentoo/gentoo-haskell/
 }}}

 That would require us to invent the URI scheme when the scm itself doesn't
 provide such names itself.

 I guess writing both the type and the location in separate fields would be
 easiest.
 Either way, I really think the type of the tool to use must be described
 or we will not be able to do much cool stuff.
