[Zope-dev] NT Service

[Toby Dickenson]

I'm suprised noone could suggest an easy way to run Zope as an NT Service, but this is so useful I thought it would be worth writing. The script below uses the service support from the win32 extensions package, at http://www.python.org/windows, although I have not tested it with the binary distributions.

Hopefully this is useful to someone else too,
