+# Example:
+# When used from local repo set REPO_ROOT pointing to file:// wth your repo
+# if your local repo follows upstream forests conventions, you may be enough by setting OPENJDK_URL
+# if you wont to use local copy of patch PR2126 set path to it to PR2126 variable

-#  sh generate_source_tarball.sh jdk8u jdk8u40 jdk8u40-b25
