There is more than one way to skin a cat; one could use the browser's
headers to determine which macro files to load, which would be robust
if you don't use fastcgi to stop "library" being loaded every time, or
properly placed would do just the job at the right point in the code
regardless of fastcgi or not.

An alternative would be to knock up a second executable which looked
at an alternative gsdlsite.cfg file, with a different set of
of course, that seems messier, but if you are on Unix/Linux and do a
symbolic link to everything but the macro directory, you can then do
all your own macros for that executable.

I'd go for the first option - a little coding but should work fine once
it's been done. However, if Pocket IE spoofs it's HTTP headers, you
may need to resort to something a bit more clever.
