# A code obfuscator for Ruby.  It works by getting a dump of the node
# tree, then wrapping it with a lightweight loader.
#
# NOTE: This code is for demonstration purposes only!  It has not been
# extensively tested, and I cannot guarantee that it works in all cases
# (I don't even know what the corner cases are).  If you wish to use
# this in a commercial product, please verify that the code is correctly
# loaded.
#
# Usage:
#
#   $ cat test.rb
#   def foo
#     1+1
#   end
#   
#   puts foo()
#
#   $ ruby -rinternal/obfusc test.rb > test2.rb
#   $ ruby test2.rb
#   2
