# This script is run by autogen to create the FULL_VERSION file.
#
# If run from a git branch, it append '.git.' + git sha1 to the VERSION file.
# If run from a svn branch, it append '.svn.' + svn number to the VERSION file.
# If run from a svn tag that match /rc/ it use only the tag name to set the
#  VERSION, this is done specifically for zmanda rc build.
# If run from a svn tag that doesn't match /rc/ it use only the VERSION file.
#
# It is important to update the VERSION file before creating a tag.
#
# ./autogen run config/set_full_version, it create the FULL_VERSION file.
# ./configure use the FULL_VERSION file.
