Trust analysis on the Debian Keyring

Drew Streib regularily ran analyses on the full PGP Keyring and publishes the results at http://www.dtype.org/keyanalyze/.

More up2date global analyses are done by Jason Harris and can be found on http://keyserver.kjsl.com/~jharris/ka/.

I use Drew's code and do the same on the Debian Keyring. As of 2005-08-31 I use a new version of Matthias Bauer's Cwot. This allegedly fixes some bugs with previous stats.
