[Zope] Applying updates to zope site

[Brian Sullivan]

I am involved in maintaining a remote Zope site that is behind a
firewall where I have no remote access.

I have a (parallel) site that I use to test changes and upgrades that
is accessible to me.  I am a looking for a straightforward way to
package tested changes, send and have changes applied at the other end
-- without my physical presence (there is a systems maintenance person
a the other with reasonable broad systems knowledge but no in depth
Zope experience). The changes in this case consist of changes to or
new python scripts, dhtml methods and documents, or images spread
throughout a hierarchy of folders on the site.

The only thing I can come up with so far is a (probably fairly painful
and error prone) set of instructions for updating files one by one.

Anybody have any other ideas?
