Python markdown

$ easy_install mark3
$ python -m mark3 < myfile.text

Or used as a python module:

from mark3.markdown import markdown
html_output = markdown(raw_text)

I wanted a markdown to html converter for python3 that was lightweight and fast. So I created mark3.
Much to my surprise I was able to get mark3 quite a lot faster than existing libraries (~7x faster).

$ hg clone https://bitbucket.org/jlm/mark3
$ cd mark3
$ python tests/speed_test.py

See the README for details on how mark3 differs from the official markdown implementation.
