folderify.rb

#! /usr/bin/env ruby
#
# Moves all the files found by the glob into a new directory of the same name 
#   as the file (less its extension). Useful when you have a bunch of examples
#   in one language and you need to introduce multiple sibling examples to sit
#   alongside the file
# 
# Example usage:
#   $ ruby folderify.rb "smells/**/*.js"
