You could also expose your script as a console_script and thus get it into bin/.

I don't see any reason why we shouldn't do this.

The code in the zope2instance recipe has diverged both in
implementation and semantics from the original Zope2 code. I tried to
push back some of that in 2.11 while porting the Windows service
support code over. But there's again a lot of other changes.

Given that this code is completely untested except for people actually
using it on different platforms I'm not personally going to merge the
codebase any further. But anyone else is free to do so given they test
the modified code under all supported platforms and especially
Windows.
