This site contains 29761 parsed manpages from sections 1 and 8 found in Ubuntu's manpage repository. A lot of heuristics were used to extract the arguments of each program, and there are errors here and there, especially in manpages that have a non-standard layout.
It is written in Python and uses a bit of NLTK (to find the interesting parts of the manpage), a little d3.js (for the connecting lines graphic) and Flask. It is served with uwsgi and nginx. I will open source the code in the near future, when I have time to clean it up a bit.
