# Makefile for releasing Tork
#
# The release is controlled from version.go. The version found there is
# used to tag the git repo and to build the assets that are uploaded to GitHub.
#
# Steps to release: 
# 1. Update version.go.
# 2. make -f Makefile.release release
# 3. make -f Makefile.release github-push
