best practice for documenting a project? pydoc?

[Esmail]

Hello,

A project that I have been working on is getting larger
and more complex, and I would like to unload some of the
information from my memory/head to some other media (a
set of web pages?). I am primarily interested in documenting
the classes/methods.

This documentation is primarily for my use only - as I can't
continuously work on this project and have to come back to it
after some time, it would be nice to have some documentation
available to help jog my memory.

What is the best way to do this in an automated way? I have
been documenting my code as I've gone along.

Is pydoc still the way to go, or should I use something else?

Thanks,
Esmail
