This way, autobuilders can run it before building, in a tree where
git-annex was already built, and get the current git rev embedded in the
build.
Before, the version number only updated when the setup program was run,
which was up to cabal and not on every build.
This turns out to have been prolimatic because building from a git tag
would make a git-annex that claimed a different version than the tag's
version.
The git rev is still included in the version, and people who want
to know the exact tree that was built can just use that, so there's no
real benefit to automatically advancing the date part of the version.
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.
It started exporting a isSymbolicLink which supports windows. But,
git-annex does no use symlinks on windows yet and this conflicts with the
function by the same name from unix-compat, so hide it.
Also automated downloading the builds, finally. I had done it by hand until
now.
Note that the Windows autobuilder has an expired cert, so it will refuse to
download from it currently. I have emailed its admin to get that fixed,
hopefully.
