[Zope] Running a script at Zope startup

[Herman Geldenhuys]

Hi

My problem is that the client connection must be started as soon as Zope
starts up. Ie, the attribute must be initialized prior to accessing it from
within the Zope context. As soon as Zope starts, my client connection must
be made, so that the remote server via a persistent connection to the
client, can invoke callback methods when an event occurs on the server's
side. So, the connection attribute is rarely ever called from within the
same "process". Is'nt there a "startup" event for Zope(event indication all
modules are finished loaded)?

Thanks again.

Herman
