[tor-dev] Hi, all!

[Nick Mathewson <nickm@xxxxxxxxxxxxxx>]

I'm about to go on vacation, but before I started, Isabela asked me
for coverage information on Tor, to help people decide where more
tests should be written.

I've re-run coverage, and uploaded the gcov output here:

https://people.torproject.org/~nickm/volatile/coverage-65a1e27.tar.bz2

That archive includes coverage on current master from
  * make check
  * make test-network (uses chutney)
  * make test-stem (uses stem)
  * all of the above, combined

I'm also attaching a script that I wrote long long ago, and use to
summarize coverage file-by-file. Example use:

gcov-lines.py ./coverage-65a1e27/cov-all/*
