# Rails autoloading, while nice in theory, frequently doesn't work. Since Rails 2.3+
# is so fast when completely reloading the server, I wrote this script to listen to the
# given directories, and kill/restart the server when any file is changed.
#
# It's quick, simple, and it reliably reloads your application when changes are made.
