# What does this release script do:
# get major.minor.micro from setup.py
# Chop off -dev tag at the end. If no dev at the end, bump the micro
# version
# commit it.
# Tag at the commit.
# Bump to the next dev version: major.minor.micro+1'-dev'
# commit it.
# Push changes and tags to remote
# How do you use a release like this:
# Get it from the GitHub by using the tag + tar ball feature
