Makefile.release

# Makefile for releasing.
#
# The release is controlled from version.go. The version found there is
# used to tag the git repo, we're not building any artifacts so there is nothing
# to upload to github.
#
# * Up the version in version.go
# * Run: make -f Makefile.release release
#   * will *commit* your change with 'Release $VERSION'
#   * push to github
#
