Doug's Freecell Goal Setter: Source Code

Doug's Freecell Goal Setter is "open source." That means that you get to look at the source code. It also means that Doug is now "cool" in the "geek" "community." Yesterday I was the merest of mere math professors. Today I am an open source pioneer, a programming outlaw who makes his own rules and doesn't even necessarily follow them. You don't want to get mixed up with me; I'm dangerous.
