#!/usr/bin/env jruby
# -*- coding: utf-8 -*-
# This script is for use with JRuby, to copy the (patched) stdlib and external test files from
# various locations in MRI's layout to JRuby's layout. It should be used
# against the jruby-specific fork of MRI's repository at
# github.com/jruby/ruby.
#
# This script selects the branch to use against with the version number, i.e: jruby-ruby_1_8_7 or jruby-ruby_1_9_3.
#
# usage: sync_ruby <tests|stdlib|all> <version(1_8_7|1_9_3|2_0_0)> <jruby ruby fork clone> <jruby dir>
#
# Example:
#
# The JRuby ruby fork is in ../jruby-ruby, and jruby is in the current directory.
# We want to sync both 1.8.7 standard libraries.
#
# $ jruby tool/sync_ruby stdlib 1_8_7 ../jruby-ruby .
# ~/projects/jruby ➔ jruby tool/sync_ruby stdlib 1_8_7 ../jruby-ruby .
# Already on 'jruby-ruby_1_8_7'
# cp -r ../jruby-ruby/lib/English.rb ./lib/ruby/1.8
# cp -r ../jruby-ruby/lib/Env.rb ./lib/ruby/1.8
