#! /bin/bash
# A script for setting up environment for travis-ci testing.
# Sets up Lua and Luarocks.
# LUA must be "lua5.1", "lua5.2" or "luajit".
# luajit2.0 - master v2.0
# luajit2.1 - master v2.1

# $HOME/.lua/lua
# $HOME/.lua/luajit
# $HOME/.lua/luac
# $HOME/.lua/luarocks
#
# Building of the targeted lua version is done in:
