# A basic mary client in Python,
# kindly donated to the MARY TTS project
# by Hugh Sasse. Thanks Hugh!

# A very basic Python class for accessing
# the MARY TTS system using the modern 
# HTTP server.
# Warning, this is probably ghastly Python,
# most of my time of late has been with 
# other languages, so I'm not up to date
# with all the stylistic conventions of 
# modern Python.
# This does seem to work OK though.
