CentOS - Sep 2009 - sed (or other) magic to get RPM base names ?

Hey folks,

Once upon a time I saw some sed magic to take the output of "rpm -qa"
and strip away all the version info to give just the RPM base names.

And of course I forgot to note it :-/   And have not been able to
replicate it myself.

e.g. from this :

avahi-0.6.16-1.el5
avahi-glib-0.6.16-1.el5

produce this :

avahi
avahi-glib

thanks,
-Alan
