# How to perform a release with git & maven following the git flow conventions
# ----------------------------------------------------------------------------
# Finding the next version: you can see the next version by looking at the 
#	version element in "pom.xml" and lopping off "-SNAPSHOT". To illustrate, 
#	if the pom's version read "0.0.2-SNAPSHOT", the following instructions would 
#	perform the release for version "0.0.2" and increment the development version 
#	of each project to "0.0.3-SNAPSHOT".

# branch from develop to a new release branch
git checkout develop
