Mercurial Linux Symposium paper

Something I thought people might be interested in: the proceedings
of the 2006 Ottawa Linux Symposium includes an interesting, if short,
paper titled "Towards a Better SCM: Revlog and Mercurial".

It describes in brief how Mercurial handles revision storage through its
revlog structure and delta storage. I know that dberlin has been looking
at using something like the former to reduce the number of files we open
during FSFS read operations; and as Mercurial uses an algorithm called
'bdiff'[1] (based on Python's difflib algorithm) rather than xdelta,
it might also be interesting to explore what kind of performance/storage
results we'd get by doing the same.

Available in volume 2 of the proceedings, pp.91-98.
