CeWL (pronounced "cool") is a ruby app which spiders a given URL to a specified depth, optionally following external links, and returns a list of words which can then be used for password crackers such as John the Ripper.

It also has an associated command line app, FAB (Files Already Bagged) which uses the same metadata extraction techniques to create author/creator lists from already downloaded.

CeWL needs the RubyGems package to be installed along with the following gems:

These can be installed by running

bundle install

from the CeWL directory. The mini_exiftool gem also requires the exiftool application to be installed.
