+# 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.
