The various django-lass-XYZ modules were split from a project that was licenced under the GPL2 due to including xapian-haystack. The terms of this licence are preserved, but the copyright holders of the code decided to licence the original code (as separate from the work including xapian) under the terms of 2-clause BSD as well. Hence the kerfuffle.
As this documentation is mostly extracted from the source, it is also distributed under the terms of 2BSD/GPL2 (for better or worse).
