SYNOPSIS

DESCRIPTION


dzhandle is the command-line utility for handling Zope servers, instances and products. It
is a system administration tool and a Debian/Ubuntu maintainer's helper script at the same

products to them, start and stop them, but it is also used by the Debian/Ubuntu Zope
packages for their installation and removal.
