Ios 7 pythonista script: takes clipboard (in Spanish) and reads it aloud (in Spanish) using Google Text to Speech

# -*- coding: utf-8 -*-
""" ios clipboard to google TTS (in Spanish) 
  This was written for ios pythonista, a python 2.x language.  It takes whatever is in the clipboard
and reads it out using google text-to-speech.  The present form takes Spanish and reads it aloud as my
interest is in learning to understand spoken Spanish.  I take text from the immersion part of
Duolingo and listen.  It should be quite easy to modify for different purposes.
  
  On a jail-broken device one can even: copy to clipboard, use activator to launch the pythonista script, and
have it start speaking!  I simple gathered some python from the web, fit it together, debugged a bit, and I
had a new tool.  Pythonista blew my mind.
"""
 
""" After each line, it gives options to quit, read all lines without pause, read next line, or
for you to write your translation.  It's still rough around the edges (and deletes everything in the
'temporary' sub-directory without confirmation), but I thought I would share it in case
others can build on it.

'''El mundo. Geografía.  La historia de Canción de Hielo y Fuego tiene lugar principalmente en el continente de Poniente.  Es aproximadamente equivalente en extensión a Sudamérica, aunque el autor quiso recrear una especie de Inglaterra medieval.  Sin embargo, hay una gran extensión de tierra al norte sin cartografiar, debido a las temperaturas extremadamente bajas y los habitantes hostiles conocidos como salvajes.   Las tierras del norte de Poniente están menos habitadas que las del sur a pesar de su extensión aproximadamente igual.   Las cinco ciudades principales de Poniente son, en orden de tamaño: Desembarco del Rey, Antigua, Lannisport, Puerto Gaviota, y Puerto Blanco.'''
