Model
Unlike most SCM software, which allows the user to view a source tree history as series of snapshots going back in time, a darcs source tree is modelled as a set of patches, where each patch is not necessarily ordered with respect to other patches i.e. the set of patches is only a partially ordered set. A particular version of the source tree corresponds to a particular set of patches; this set of patches may or may not have existed at some other point in time.

“I had a wonderful job. I worked for a big model agency in Manhattan.... When I got on the subway to go to work, it was like traveling into another world. Oh, the shops were beautiful, we had Bergdorf’s, Bendel’s, Bonwit’s, DePinna. The women wore hats and gloves. Another world. At home, it was cooking, cleaning, taking care of the kids, going to PTA, Girl Scouts. But when I got into the office, everything was different, I was different.”
—Estelle Shuster (b. c. 1923)
