"""This script builds the Lib/fontTools/ttLib/tables/otData.py file
from the OpenType HTML documentation. However, it depends on a slightly
patched version the the HTML, as there are some inconsistencies in the
markup and the naming of certain fields. See doco.diff for differences,
but this is probably against a slightly older version of the documentation
than what is currently online. The documentation was taken from this URL:
http://www.microsoft.com/typography/otspec/default.htm
