Documentation on the binary file format?

["M. Edward (Ed) Borasky" <znmeb@cesmail.net>]

Is there some documentation on the binary file format out of "blktrace"?
I'm interested in writing some post-processing routines that extend what
"blkparse" and "btt" do, and there is a substantial disk space hit if I
generate the "blkparse" output and post-process that. I'm also
considering a network server that takes the binary data from a
"blktrace" client and does the analysis "on the fly", rather than saving
off a binary trace.

A side question ... how likely are changes in the binary format? The
language(s) I want to use -- Perl and/or Ruby -- are pretty flexible at
re-factoring to match format changes, but I'd like to have a clue on how
much maintenance activity I'm taking on.
