Jordan Justen brought to my attention that, according to the Apache and
GNU websites, Apache 2.0 is incompatible with GPLv2 because GPLv2 lacks
a patent indemnification clause. (It is compatible with GPLv3, however).
See [1] [2] [3].

By the same logic, a lawyer could argue that Apache 2.0 is also
incompatible, in one direction only, with minimal gift licenses such as
BSD and MIT.

I do not want license incompatibility to prevent any project from using
Waffle's code, so I'm converting the project to use the most liberal
license possible, BSD 2-clause [4].
