# Generate a version string for use when building.
#
# * If RELEASE exists, and is non-empty, use the contents of that file.
#   This is in case we're building from a tarball.
#
# * If we're inside a git tree:
#   - For the "master" branch, use "git describe".
#   - For "detached" branches (mostly for tag checkouts), also use "git describe".
#   - For other branches, use a "$VERSION-$NBCOMMITS-$BRANCH-$DATE-g$COMMIT"
#     sortof version.
#
# * Try to make it up from the directory name (munin-2.0.1 -> 2.0.1)
#
# * If we're still looking for a version, just fallback to "unknown".
