characterization of other version control systems

Wow, great stuff. A few nitpicks I will file as issues. starting off:

Intro make it sounds a bit too much like git is the only distributed control system. (mecurial is also distributed). Perhaps unnecessary to emphasize the 'distributed' part so much, since I'm guessing most the audience comes from the final_draft_V3.doc school of management rather than the subversion school.

Start with the introduction discussed in the issue and review how it frames Git as a distributed version control system. Done means the introduction no longer overemphasizes distribution and acknowledges other distributed systems such as Mercurial, while preserving the paper’s intended explanation.
