# In general, versions should be: <major>.<minor>.<micro>[-<human-readable-tag>]
# * Human readable tag should not have any dots in it
# * SNAPSHOT is used for development
# 
# Master before release:        x.y.z-SNAPSHOT (or x.y-SNAPSHOT in which case we treat it as x.y.0-SNAPSHOT)
# at release:                   x.y.z-Helium
# stable/helium after release:  x.y.(z+1)-SNAPSHOT
# master after release:         x.(y+1).0-SNAPSHOT
# Autorelease on master:        <human-readable-tag> is "PreLithium-<date>"
# Autorelease on stable/helium: <human-readable-tag> is "PreHeliumSR1-<date>"
# Release job on master:        <human-readable-tag> is "Lithium"
# Release job on stable/helium: <human-readable-tag> is "HeliumSR1"
#
# Some things have a date for a version, e.g., 2014.09.24.4
# * We treat this as YYYY.MM.DD.<minor>
# * Note that all such dates currently in ODL are in YANG tools
# * They are all now YYYY.MM.DD.7 since 7 is the minor version for yangtools


# The goal of this script is to:
#   1.) take all x.y.z-Helium versions to x.y.(z+1)-SNAPSHOT and
#   2.) take all x.y.z-SNAPSHOT versions to x.(y+1).0-SNAPSHOT
