# Generates the 'source tarball' for JDK projects.
#
# Example:
# When used from local repo set REPO_ROOT pointing to file:// with your repo
# If your local repo follows upstream forests conventions, it may be enough to set OPENJDK_URL
#
# In any case you have to set PROJECT_NAME REPO_NAME and VERSION. eg:
# PROJECT_NAME=openjdk
# REPO_NAME=jdk17u
# VERSION=jdk-17.0.3+5
# or to eg prepare systemtap:
# icedtea7's jstack and other tapsets
# VERSION=6327cf1cea9e
# REPO_NAME=icedtea7-2.6
# PROJECT_NAME=release
# OPENJDK_URL=http://icedtea.classpath.org/hg/
# TO_COMPRESS="*/tapset"
#
# They are used to create correct name and are used in construction of sources url (unless REPO_ROOT is set)
# This script creates a single source tarball out of the repository
# based on the given tag and removes code not allowed in fedora/rhel. For
# consistency, the source tarball will always contain 'openjdk' as the top
# level folder, name is created, based on parameter
#
