In the early 2000s, anyone I described this sort of tool to thought it
was crazy and would never work.  Merge *after* commit?  Branches with
*multiple* heads?  *Content addresses* in history graphs?  *No*
canonical servers?  Now all this is the standard, and we're quibbling
over who does it fastest.

Who cares?  The battle is won: DVCS technology works fantastically
well -- using the model we pioneered -- and free implementations of it
are absorbing many major projects.  That's cause for celebration.
