building a non-source RPM

[rpjday <rpjday mindspring com>]

  i'm throwing together a quick writeup on how to build a non-source
RPM, since that subject has come up a number of times recently in my
social circle.  

  being a newbie at this, i've tested an example involving just
bundling up some image files into an RPM, but it builds as an
i386 RPM -- how do i get it to construct a "noarch" RPM
automatically?  i didn't specify an architecture anywhere,
so i'm assuming it's getting a default from, where?  
/usr/lib/rpm/macros?

  anyway, the build is working nicely, i just need to know
how to specify the architecture.

  more questions to follow, i'm sure.
