AC_PREREQ([2.63])
dnl To do a release, increment this number, commit, then submit it as a PR
dnl to merge via homu.  After that, do `git pull origin && git reset --hard origin/master`.
dnl Then draft release notes highlighting changes and generate the shortlog using
dnl <https://github.com/cgwalters/homegit/blob/master/bin/git-shortlog-with-prs>.
dnl Then use <https://github.com/cgwalters/git-evtag> to create a signed tag with the
dnl release notes as its content.
dnl Then git push origin v201X.XX.
dnl Then create the xz tarball from `make -f Makefile.dist-packaging dist-snapshot`.
dnl Then create a GitHub release for the new release tag and attach the tarball.
