buildAll v1.2 - Dec 01 2019

This script takes a path to a folder as input, finds all UFO files or Type 1
fonts (.pfa files) inside that folder and its subdirectories, and builds
OpenType (.otf) fonts using the FDK's makeotf tool.
If a path is not provided, the script will use the current path as the topmost
directory.
The script ignores Multiple Master PFA fonts, usually named 'mmfont.pfa'.
The Type 1 fonts can also be in plain text format (.txt) where the Private
and CharStrings dictionaries are not encrypted. These files can be created
by using the FDK's detype1 tool.

==================================================
Versions:
v1.0 - Feb 22 2013 - Initial release
v1.1 - Aug 04 2013 - Added support for UFO files
v1.2 - Dec 01 2019 - Python 3
