# Generates the 'source tarball' for JDK 8 projects and update spec infrastructure
# By default, this script regenerate source as they are currently used. 
# so if the version of sources change, this file changes and is pushed
#
# In any case you have to set PROJECT_NAME REPO_NAME and VERSION. eg:
# PROJECT_NAME=jdk11
# REPO_NAME=jdk
# VERSION=inDevelopment (but keyword tip will still do its job)
# 
# If you don't, default are used and so already uploaded tarball regenerated
# They are used to create correct name and are used in construction of sources url (unless REPO_ROOT is set)
# 
# For other useful variables see generate_source_tarball.sh
#
# the used values are then substituted to spec and sources
