Getting a list of applications and packages on my Fedora machine !?

[William Case]

I think I remember reading a suggestion here about how to get a list of
the main or core programs on my machine.  It was -- I think -- an rpm or
yum list command of some kind + grep.  I don't want every plugin or
update or library just the main program.

I am about to do a virgin install of Fedora 16 (because its about time I
started fresh rather than with preupgarde again ) and I would like to
get a simple editable list of all the stuff I now have. 

It was one of those things that you say "hey neat" but don't save.  Now
I can't replicate it.
