git-annex/Build/Version.hs
Joey Hess f79875ef3b
Updated cabal file explictly lists source files.
The tarball on hackage will include only the files needed for cabal install;
it is NOT the full git-annex source tree. While it's totally obnoxious that
cabal files need every file listed out when basic wildcard support could
avoid hundreds of lines, and have to be maintained when files are added,
this does get the tarball size back down to 1 mb.

This also stops stack from complaining that it found modules not listed in
the cabal file.

debian/changelog, debian/NEWS, debian/copyright: Converted to symlinks
to CHANGELOG, NEWS, and COPYRIGHT, which used to symlink to these instead.
This avoids needing to include debian/ in the hackage tarball.

Setup.hs: Build man pages at install time using make and mdwn2man.
If it fails, which it probably will on windows, just skip installing
them.
