Author Notes (04 December 2005):
This module has gone through quite a few phases of change. Obviously,
I am only supporting that part of the code that I use. Initially
I had the upload directory as a part of zope (ie. uploading files
directly into Zope), before realising that there were too many
complex intricacies within Zope to deal with. Zope is one ugly piece
of code. So I decided to complement Zope by an Apache server (which
I had running anyway, and doing nothing). So I mapped all uploads
from an arbitrary server directory to an arbitrary web directory.
All the FCKeditor uploading occurred this way, and I didn't have to
stuff around with fiddling with Zope objects and the like (which are
terribly complex and something you don't want to do - trust me).
Maybe a Zope expert can touch up the Zope components. In the end,
I had FCKeditor loaded in Zope (probably a bad idea as well), and
I replaced the connector.py with an alias to a server module.
Right now, all Zope components will simple remain as is because
I've had enough of Zope.
See notes right at the end of this file for how I aliased out of Zope.
Anyway, most of you probably wont use Zope, so things are pretty
simple in that regard.
Typically, SERVER_DIR is the root of WEB_DIR (not necessarily).
Most definitely, SERVER_USERFILES_DIR points to WEB_USERFILES_DIR.
