My intention:

This code is provided as a proof-of-concept. It is open source for demonstration purposes, and for users to use (i.e. compile and run) to solve the problem at hand which I wrote it for. I explicitly do not want it redistributed in any fashion: this code is not suitable for commercial or public use in any way, and should very probably not be trusted with your data. 

Part of the BSD license also applies: (though I don't think it's necessary to be in ALL CAPS like they wrote it.)
