They accept parameters for them, ie. --images=../cvs-images if you are
using texitheque :)  Well, templates are not intelligent, but at least
they can be taught how to behave.

Yes, I don't see a problem with that, ie. a script having its template
with itself.

We initially decided that html files won't end up in sub directories,
so it will only prepend '../' (for cgi-bin).  It's not an issue
though, to change this (to add a new parameter).

Hm, no, we can't do that.  We have to use ../ instead of cgi-bin/
because files do not need to know where they end up, but they need to
know where stylesheets and images ended up (in a browser's point of
view, since the requests will be made by a browser).  For example
a file has @htmlprefix{../}, then the stylesheet location will become
../css/default.css (instead of css/default.css).  We can then put that
file in cgi-bin/ or html/foo/; browsers will find the stylesheet in
both locations.  (Remember, html/ directory is invisible to browsers,
so they are /foo/ and /cgi-bin/ .)

I was planning to use $0 for template names.  So you can use the same
script (ie. gallery) for two different pages (ie. logo-submissions vs.
screenshots).

In httpd.conf:
  ScriptAlias /cgi-bin/logo-submissions /web/beast/cgi-bin/gallery

But it's not a problem, ../html/$0.html as the template name is ok.

Let me try how things will work in practice tonight.

Yes.  Actually they share a very big portion of similar code.
