TrueType/OpenType Table Modules
###############################
This folder is a subpackage of :py:mod:`fontTools.ttLib`. Each module here is a
specialized TT/OT table converter: they can convert raw data
to Python objects and vice versa. Usually you don't need to
use the modules directly: they are imported and used
automatically when needed by :py:mod:`fontTools.ttLib`.

The Python modules representing the tables have pretty strange names: this is due to the
fact that we need to map TT table tags (which are case sensitive)
to filenames (which on Mac and Win aren't case sensitive) as well
as to Python identifiers. The latter means it can only contain
[A-Za-z0-9_] and cannot start with a number.
