This is an unmodified selection of code I wrote for and under contract to AT&T, so AT&T holds all copyright.
AT&T released it to the public under the terms of the Apache 2.0 License (as described in license headers in the source code) as part of a larger body of work.
I retrieved these copies from their public repositories on 1/9/2018 after I was no longer under contract to them. I am hosting it here in compliance with the terms of their license. The links below point to AT&T's public repositories.
