By hand!? I thought they had a rule in Programming School against doing
repetitive tasks by hand like that. :-)

'gcc -pg' does this. And most likely there are other tools too.

You're looking in the wrong place. I'd focus on the server side, and
there --- on one of the libsvn_* libraries (e.g., fs, delta, or subr).
subversion/svn/ contains only the code specific to the command-line client
'svn'; you can safely ignore it unless you don't see the issue with other
clients.

There is a design diagram somewhere... (notes/*.html?) And if there
isn't, perhaps we should write up somewhere the libsvn_* interaction
DAG.
