# TextileMarkdownMML.pl
#
# Provides two MT text filters
#
# Textile+itex2MML
# Markdown+itex2MML
#
# You must have the itex2MML, Textile 1.1 and Markdown filters already installed
# This filter first runs your text through itex2MML and then through
# either Textile or Markdown.
#
# The Textile+itex2MML filter requires a small patch to the Textile 1.1 plugin.
# See:
# http://golem.ph.utexas.edu/~distler/blog/archives/000374.html
#
# Based on textileMML.pl, by Yuan-Chung Cheng.
