ufo2pfa v2.0 - Feb 03 2016

This script takes a path to a folder as input, finds all the UFO fonts
inside that folder and its subdirectories, and converts them to Type 1
fonts (.pfa files). If a path is not provided, the script will use the
current path as the top-most directory.

==================================================
Versions:
v1.0 - Feb 23 2013 - Initial release
v2.0 - Feb 03 2016 - Modernized and removed defcon and ufo2fdk dependencies.
