Now for some fun ...

Let's say you are building packages using Fedora CVS.

The last time I used Fedora CVS, the work flow went something like
     cd /S/FC/devel/time		# <== note "/S/FC" is where my checkout is
     cvs up
     make i386
     ls i386/*.rpm

So "+bing" can now be used to select *.rpm packages
directly from where they reside with this macro override:

	%_rpmgi_pattern_glob    /S/FC/devel/%{NEVRA}/i386/

Then to install, say, the just built time package, one types

	rpm -Uvh +time

For extra credit, let's assume that you have all Fedora 8 packages
in /S/FC/packages as well as a cvs checkout. Try this

	%_rpmgi_pattern_glob    /S/FC/devel/%{NEVRA}/i386/:/S/FC/packages/

to look first for newly built, and use "released" if not rebuilt  
locally from cvs.

Enjoy!

Hint: rpmio permits the paths to be URL's, but I haven't quite gotten  
there yet ...
