"""
 Convert English to Openglopish.

 The rules we'll use are :
    * Insert 'op' before each consecutive string of vowels.
    * Preserve capitalization of words.
 This isn't, I think, quite 'standard' Openglopish
 (if there is such a thing), but close enough for this exercise.
 See http://en.wikipedia.org/wiki/Opish for details on this 'language game'.

 This file was put together for a demo for a python programming course.
