# Usage: ./make_release.sh
# Creates a tar.gz archive of the current tree.
#
# To bump the version number for the current commit (make sure you are in HEAD!), run manually:
#
# git tag -a v0.12 -m 'Version 0.12'
#
# To generate a release for an older tagged commit, first list the tags with:
#
# git tag
#
# then checkout the tagged commit with:
#
# git checkout tags/v0.1
#
# Finally, to revert to HEAD:
#
# git checkout master
