# To build a release you need to create a tag with the version number
# (git tag -s libassuan-n.m.k) and run "./autogen.sh --force". Please
# bump the version number immediately after the release and do another
# commit and push so that the git magic is able to work. See below

# To start a new development series, i.e a new major or minor number
# you need to mark an arbitrary commit before the first beta release
# with an annotated tag. For example a 2.1 branch starts off with
# the tag "foo-2.1-base". This is used as the base for counting
# beta numbers before the first release of a series.
# Below is m4 magic to extract and compute the git revision number,
# the decimalized short revision number, a beta version string and a
# flag indicating a development version (mym4_isbeta). Note that the
# m4 processing is done by autoconf and not during the configure run.
