iverilog/scripts/MAKE_RELEASE.sh

#!/bin/sh

# This script makes a release from a git repository. The input is
# the number for a snapshot and the path to a temporary directory.
# for example:
#
#    sh scripts/MAKE_RELEASE.sh 0.9.1 ~/tmp
#
# The above assumes that there is a tag "v0_9_1" at the point
# to be released. (The tag has the "v", but the argument to this
# script does not have the "v"). This script extracts based on the
# tag, uses the temporary directory to stage intermediate results,
# and finally creates a file called verilog-0.9.1.tar.gz that
# contains the release ready to go.
#
# The complete steps to make a release x.y.z generally are:
#
#   git tag -a v0_9_1
#                 (Make the tag in the local git repository.)
#
#   sh scripts/MAKE_RELEASE.sh 0.9.1 ~/tmp
#                 (Make the snapshot bundle verilog-0.9.1.tar.gz)
#
#   git push --tags
#                 (Publish the tag to the repository.)
#

# The prefix is the directory that contains the extracted files
# of the bundle. This is also the name of the bundle file itself.
