WHOA!!!  Edmund, you and I got our wires *WAY* crossed.

I had something completely different in mind: an engineering proof of
concept for the Gutenprint CUPS driver to be able to read a settings
file and use it.  Whether that settings file/stream comes from a
separate file, embedded in the PPD, or embedded in an ICC profile
doesn't matter for this purpose, so I thought we were talking about
sticking it in a file whose name is embedded in the PPD file
(obviously, that would be entered manually).  I just stuck in the
first place that came to mind, which is clearly not what where it
would go in production.

The issue of where to store the settings file is completely separate.
That's something the OpenICC and OpenPrinting architects need to work
