# == Class: etherpad_lite
#
# Class to install etherpad lite. Puppet acts a lot like a package manager
# through this class.
#
# To use etherpad lite you will want the following includes:
# include etherpad_lite
# include etherpad_lite::mysql # necessary to use mysql as the backend
# include etherpad_lite::site # configures etherpad lite instance
# include etherpad_lite::apache # will add reverse proxy on localhost
# The defaults for all the classes should just work (tm)
#
#
