Hi all,
this was already posted on Turbogears mailing list but here is more
appropriate,
is anyone using Bonjour/Zeroconf in Paste?
I found useful for testing purposes in Turbogears.
I googled around and haven't found anything so i grabbed some code
from turbogears/startup.py
and adapted to Paste httpserver.py.
Applied the patch just add bonjour=True do [server:main] section of
config, if you want you can add also server_name and
server_description to the same section of the ini file.
Michele.
