+a ua-parser accelerator
+=======================
+
+This package is (currently) not intended to be used directly, instead
+it is one of the native accelerators for [ua-parser][1].
+
+The API is very simplistic and should be pretty stable (if only
+because having to update [ua-parser][1] all the time is undesirable),
+but there is no formal guarantee that it'll keep, as the goal is
+really nothing more than a very basic export of [uap-rust][2] to
+Python.
