# Generates the 'source tarball' for JDK 8 projects.
#
# Usage: generate_source_tarball.sh project_name repo_name tag
#
# Examples:
#   ./generate_source_tarball.sh jdk8 jdk8 jdk8-b79
#   ./generate_source_tarball.sh jdk8u jdk8u jdk8u5-b13
#   ./generate_source_tarball.sh aarch64-port jdk8 aarch64-${DATE}
#
# This script creates a single source tarball out of the repository
# based on the given tag and removes code not allowed in fedora. For
# consistency, the source tarball will always contain 'jdk8' as the top
# level folder.
