This site is mostly for me personally. After years of dragging reference material from site to site, file format to file format, I decided my personal website needed to be a repository for the stuff I need to hold on to.
I created a project to do this, and I've been dumping documentation into this site ever since.
It's organized by topic, if would be great if any of the material collected here helps you in any way. However, don't hold your breath.
