#!/bin/bash

# Generates the 'source tarball' for JDK 8 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

# If you want to use a local copy of patch PR3667, set the path to it in the PR3667 variable

#

# In any case you have to set PROJECT_NAME REPO_NAME and VERSION. eg:

# PROJECT_NAME=jdk8u   OR   aarch64-port 

# REPO_NAME=jdk8u60    OR   jdk8u60 

# VERSION=jdk8u60-b27  OR aarch64-jdk8u65-b17 OR for head, keyword 'tip' should do the job there

# 

# 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
