# This script checks the java version and bails if it's less
# than Java6 (because we use @Override annotations on interface
# overriding methods.  It then proceeds to do a maven build that
# first cleans, then builds the normal lifecycle through compilation
# unit testing (if available) up to packaging.  It then packages
# the source, javadocs, and maven site.  It then signs the 
# artifacts with whatever pgp signature is the default of the 
# user executing it, and then deploys to the repository contained
# in the distributionManagement section of the pom.
