############################################################################
# This parser is based on an earlier CMS parser implementation.
# It has been completely rewritten and generalized for Kunena and
# was also heavily tested.
# However it should be: extensible, fast, ungreedy regarding resources
# stateful, enforcing strict output rules as defined
# Hope it works ;-)
