update

#!/bin/bash
#
# Usage: update [restart|noop [<refspec>]]
#
# Examples:
#   update                 # deploy latest
#   update restart         # deploy latest and restart services
#   update restart v1.2.3  # deploy ref "v1.2.3" and restart services
#   update noop v1.2.3     # deploy ref "v1.2.3"
#
# If <refspec> is not given, no "git checkout" is performed thus you get the
# latest version of whatever branch you are currently at.
