TITLE: Looking for Open Source Math Software with Poor Documentation
QUESTION [18 upvotes]: I'm a techie who is looking to transition to technical writing as a career. It's been suggested that I produce documentation for an Open Source project to demonstrate my ability to do technical writing. I love Math so I thought I'd find a gap in an Open Source Math program and fill that gap.
What poorly documented Open Source Math software can you recommend that I look at?

REPLY [3 votes]: Take a look at this project http://www.formulae.org It is open source, it is about math and it is partially documented.
There are several sources for documentation: the developer's guide (LaTeX, partially), the front-end user´s guide (LaTeX, starting), the API reference (JavaDoc, partially) and expression dictionary (online wiki, partially)
