3 # This script walks through a Lintian laboratory and counts license usage
4 # based on matching regexes against the contents of the copyright files. It's
5 # intended to provide a rough estimate of the number of packages using a
6 # particular license when discussing whether to add a license to base-files.
8 # It expects one argument, which should be the root of the Lintian laboratory.
