If you want to change the default font that is used when displaying
zephyrgrams, you need to include the following line in your .Xresources file:

	zwgc*style*substyle.default.fontfamily:		times

This would use "times" as the default font.  You can use one of the predefined
fonts: times, helvetica, or courier (which is the Athena default) -- Or, if
you have defined your own fontfamilies in your .Xresources file, you can use
one of those names.

Of course, once you have changed your .Xresources file, you will have to
reload the X Resource DataBase manager by typing:

	xrdb  ~/.Xresources

and then you'd have to kill and restart your zwgc in order to see the new
fonts (or just wait until next time you log in).

fonts under the XWINDOWS topic.
