This license file applies to everything in this repository except that which is
explicitly annotated as being written by other authors, i.e. the Boost queue
(included in the benchmarks for comparison), Intel's TBB library (ditto),
dlib::pipe (ditto), the CDSChecker tool (used for verification), the Relacy
model checker (ditto), and Jeff Preshing's semaphore implementation (used in
the blocking queue) which has a zlib license (embedded in
lightweightsempahore.h).
