#!/bin/sh
# This script prepares and tags a release in the git repository. The tag is
# based on the first and second argument passed to the script, which should
# be the desired major and minor numbers for the release. Before creating the
# tag, autoconf.sh will be run to create the configure and lexor_keyword.cc
# files, the version_base.h and verilog.spec files will be updated to reflect
# the new release ID and a release_tag.h file will be created in the top level
# directory to provide the VERSION_TAG macro. After creating the tag, the
# configure, lexor_keywords.cc, and release_tag.h files will be deleted.
#
# The complete steps to publish a release are:
#
# sh scripts/CREATE_RELEASE.sh
# (Create the tag and version info in the local repository)
#
# git push --follow-tags
# (Push the commits and tag to the remote repository.)
#
# For a major release, create and switch to the new release branch before
# running this script. See: scripts/CREATE_BRANCH.sh
