Seeking areas of little or weak documentation

Hi,

I've been a techie for lots of years and I love Math although I'm new to
Maxima. I'm looking to make a career change to becoming a tech writer and
it's been suggested to me that I document a piece of an Open Source package
to demonstrate my ability to do technical writing. So, here I am.

Can list members point me to areas of Maxima that could most use
documentation help?

Thanks.

Sol
