webstats
webstats is a python3 HTTP logs analyzer licensed under GPLv3. It also contains a log anonymizer which replaces IP addresses by hashes.
It is a one-day hack for school so this first version is very basic.
Feel free to send me patches, bug reports or feature requests.
Source code is available at git://changaco.oy.lc/webstats.git
and browsable via gitweb.
