 This is a work-in-progress but it's deemed stable enough to be made public.
 *Note that, while the interface with OpenDSS is stable (classic version), the OpenDSS-PM (actor-based parallel machine version) interface was integrated recently and is experimental.*

 =======
 Besides bug fixes, the main funcionality of this library is mostly done. Notable desirable features that may be implemented are:
 
-- More and better documentation, including the integration of the help strings from the IDL/COM definition files.
+- More and better documentation
 - Create wheels for Linux distributions, maybe using the Anaconda stack.
 - Create a more "Pythonic" API. This would break compatibility with COM, but may result in a more pleasant environment for using OpenDSS in Python.
