New Revision: 24322
Added:
py/dist/py/execnet/script/socketserverservice.py
Log:
This is a first cut at a Windows service wrapper around py.execnet
socketserver. It's barely tested, and doesn't log anything, but it may
serve as a proof of concept. It Worked For Me Once (tm).
Added: py/dist/py/execnet/script/socketserverservice.py
