Controlling Fonts and Font Sizes in GTK Applications

[Hal Vaughan <hal@halblog.com>]

I have a Debian system hooked up to an HDTV.  I'm using KDE as the DE  
and have had no problem adjusting the fonts used by KDE apps so they  
are big enough to see from across the room, but I'm stuck with itty- 
bitty fonts for Firefox and other GTK based apps.  When I search with  
apt-cache, I find only gxset, which doesn't allow for setting fonts  
(at least not in Lenny).  I've tried Google, but if it's obvious, I'm  
not using the right terms.

What can I use to set the default fonts and font sizes for GTK programs?


Thanks!
