+I've just finished rewriting my [PID][] temperature control package in
+pure-Python, and it's now clean enough to go up on PyPI.  Features:
+
+* Backend-agnostic architecture.  I've written a first-order process
+  with dead time (FOPDT) test backend and a [pymodbus][]-based backend
+  for our Melcor MTCA controller, but it should be easy to plug in
+  your own custom backend.
+* The general PID controller will automatically tune your backend
+  using any of a variety of tuning rules.
+
+The `README` is posted on the [PyPI page][pypi].
