understanding darcs

I was supposed to spend my day off doing laundry, getting my hair cut, and running a million little errands, but instead I spent it writing my patch theory introduction in Understanding darcs. Oh well, at least I now know how merging works in the very simplest non-conflicting cases. Typical pattern for me. If I want to understand how something works, the best way for me to go about it is to write something in wikibooks about it.
