I love it when I think "I need a document to _____." and then I find out that I’ve already written it. Documentation is such a good thing! Programmers that think they will "get around to documenting after the project" or that "no one ever uses documentation" must suffer a lot on maintenance projects or when additional work comes around. I bet they say "it would be cheaper and easier for me to just start over" a whole bunch.
documentation. bah
