Hi Angus,

Another approach I've seen and am thinking might work out 'better' (for
example would not need a change to the Admin UI) is the introduction of a
catalog_local.cfg which is included in catalog.cfg

Instead of having site.txt you'd have the Variable settings in
catalog_local.cfg ...
In your case that would make a catalog_tech.cfg , catalog_ar.cfg symlinked
at the right locations.

I think that either approach would work, but considering a couple of things
the catalog_local.cfg approach might have slightly more pros:
- catalog.cfg is really about configuring your catalog,  variable.txt is
more focused on display ( I think ) ... 
- the actual start of using site.txt in the demo would require an update to
the Admin UI

So I suppose I change my proposal slightly to become:
- remove site.txt from standard
- introduce catalog_local.cfg to move the things to that I had marked with a
* in my previous mail
- include catalog_local.cfg in catalog.cfg

This change I do not think would hurt existing catalogs and will not cause
any backward compatibility isues as it would be part of the creating of a
new catalog.
