# Creates a release tarball directly from git
|
|
|
|
# Note that the tarball contents might not exactly match
|
|
# a particular git commit, particularly for untagged
|
|
# commits.
|
|
#
|
|
# An alternative approach would be to generate source tarballs
|
|
# using CPack. That would remove our dependency on git, but if
|
|
# Autotools is any indication it would require continuous
|
|
# maintenance.
