Versioned scripts in Zope packages

Hi,

Perhaps I should have re-read the Python policy before sending an email,
sorry about that.

I  agree with  you for  repozo. The  versioned scripts  should  be added
whenever it  is relevant. For example for  buildout and zope.testrunner,
it  is definitely  useful and  adding an  extra dependencies  because of
versioned scripts is not a problem in these cases IMO.

You may want  to run buildout with several  different versions of Python
and you usually  do... Yes, you may do  python2.X /usr/bin/buildout, but
in such cases it might be better to have versioned scripts.

That's indeed a problem. I didn't notice that at first.

I don't  know so much about  zdaemon, so maybe that's  pointless to have
versioned scripts. If  so, I will remove them and  upload it, no problem
at all.

That would be great if you could do it.
