Getting $(allclasses) into a shellcommand

[Chip Seraphine]

I have some truly enormous $(allclasses) strings as a result of using cfengine 
to maintain my RPM distributions.  (If you define one 15-to-25 character 
class for every RPM you need installed, and you need a few hundred RPMs right 
after a clean kickstart....)

Anyway, I am having issues passing these large lists of classes into the perl 
script that does the actual RPM installation.   Mark enlarged a buffer 
somewheres when I had this problem earlier, but said buffer has been 
outgrown...    I'd like to find a Proper Solution to this.

What is a better way than "/some/command $(allclasses)" for doing this sort of 
thing?  Is there some kind of iterator-type trick  anybody knows?
