/itexToMML

# 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
