[Zope-Checkins] CVS: Zope/inst/skel/inst/skel/bin - ntservice.py:1.1.2.1

[Chris McDonough]

Update of /cvs-repository/Zope/inst/skel/inst/skel/bin
In directory cvs.zope.org:/tmp/cvs-serv16746/inst/skel/inst/skel/bin

Added Files:
      Tag: chrism-install-branch
	ntservice.py 
Log Message:
Added support for creating NT services from instance homes.

This works by building an instance home normally and then from the
instance home running "bin\ntservice.py install".  The service is named
after the instance, and each instance can have its own service installed.

In the process, moved "zctl.py" into a "bin" directory, and moved "zope.conf"
into an "etc" directory inside an instance home.
