I also found the introduction about 'darcs' being too academic quite
silly. However at the end of his invited rant Linus proposes a requirement
(or may we call it 'axiom'?), that would be nice to be have: An identifier
(a 'version') that can be uniquely mapped to a set of files and their
contents. In Darcs this is the darcs history and it is usually the largest
part of submitted darcs patches.
