# The veralign script sets the appropriate versions in all of
# the package configuration files for all of the supported
# languages.  It is used to prepare a release or move master
# forward to the next anticipated version.
#
# USAGE
# -----------------------------------------------------------
# usage: veralign.sh <oldVersion> <newVersion>
#
# EXAMPLE
# -----------------------------------------------------------
# $ ./veralign.sh 0.12.0 1.0.0
# $ ./veralign.sh 1.0.0 1.1.0
#
# IMPORTANT USAGE NOTE
# -----------------------------------------------------------
# Define the environment variable DRYRUN to have the script
# print out all matches to the oldVersion hilighted so that
# you can verify it will change the right things.
