#
# This program is a re-write of the original DocMaker took used
# to generate the API Reference of the FreeType font engine
# by converting in-source comments into structured HTML
#
# This new version is capable of outputting XML data, as well
# as accepts more liberal formatting options
#
# It also uses regular expression matching and substitution
# to speed things significantly
