Thanks for creating that page.  Looks line a fine start, though you'll
want to automate more things when looking at 2012 tarballs.

grep and friends are fine tools to process Tor descriptors.  If you can,
find a Unix/Linux-like environment for Windows (Cygwin?) and combine the
powers of grep with sort, uniq, and maybe sed or awk.  These tools are
friggin' fast!

If you're comfortable with Java and want to do more fancy stuff with Tor
descriptors, take a look at metrics-lib:


If you're a Python person, you'll like stem, even though it only
implements parsing of a subset of Tor descriptors.  More to come soon:
