# This creates the x.y.z.yaml file for releasing (java) artifacts.
# It should be executed from somewhere within the "git" repo to be
# released.  Assumes the following:
#   - the branch to be released is currently checked out
#   - the latest maven-stage jenkins job is the one to be released
#   - the defaultbranch within the .gitreview file is set to the
#     branch to be released
#
# This uses xmllint, which is part of the libxml2-utils package.
#
# If behind a firewall, then http_proxy must be set so that curl
# can get through the firewall.
#

# Use the bash internal OSTYPE variable to check for MacOS
