This issue is hard to solve in a way that doesn't penalize

one side or the other:

   - People using WYSIWYG tools expect the expansion of METAL
     macros, so that the templates look as they will when used
     "live";

   - People who use the textarea, or a text-based WebDAV/FTP
     editor, typically *don't* want the expansion, which obscures
     the "real" parts of the template.

Perhaps we should patch PageTemplates to use some configurable
switch (an environment variable, or a command-line switch?  A
globally-acquired attribute?) for the default value now stored
in 'PageTemplate.expand'.

Another alternative would be to add a knob to PageTemplate which
strips out everything that supplied by METAL (maybe we spell that
by supplying the path to an "empty" template, an do the expansion
using the empty template, followed by setting 'self.expand=0'?)
