What a relief! Thanks for scratching that itch. Also turns out to be good code organization, but I needed that post to boot me up.

Someone should make a site for sharing little "guided tours" of open source code bases...

While not a walk through the code base, there are these wonderful volumes: http://www.aosabook.org/en/index.html that have creators/maintainers/contributors walk through at a higher level how these amazing programs work.
