script to compile a rails app with jrubyc and bundle

bundle-compiled.sh

#!/bin/bash
#
# Script to bundle this rails app with compiled ruby files.
# The main problem is that rails very much assumes that files
# end in ".rb", although jruby is also fine with loading
# ".class" files.
#
# The "solution" is to replace each ".rb" file with a file
# which loads the associated ".class" file.

    cp -a $i bundle/

jrubyc -t bundle app lib
