[ic] Changing a catalog variable

[Kaare Rasmussen]

Is it possible to change a catalog varible dynamically?

I have _one_ page where I don't want the default logo. The logo is displayed 
with __THEME_LOGO__ in the top templates but I would like to be able to do 
something like

[tmp __LOGO__]newlogo.png[/tmp]
@_ONLY_TOP_@
... the rest of the page...

(Only an example; you get the idea).

Is this possible?
