[gentoo-user] How to know the fonts inside various font packages

How can user learn the exact fonts contained in the various font
package offered in portage without actually installing them?

Even after installing, unless you have something like xlsfonts
installed you still won't be able to tell.

equery files <font-pkg>

Gives a list of the files installed but the naming is way different
from what you see or need to use when assigning a specific to be used
in some app.

And of course using equery already means you've had to install the
font.

I want to find this information before installing a font package.

I ask because I'm building up a new install, trying mirror or nearly
so my previous install which was yrs in the making.

I looked under /var/db/pkg/media-fonts in backups from the previous
install and find no less than 38 font pkgs installed.

I don't as a rule use anything far out... I like fonts assigned to
emacs and xterm... thats about it.  And those are common ones like
 -misc-fixed-bold-r-normal--18-120-100-100-c-90-iso8859-1

But on a fresh install that particular one is missing.  I'd like to
have been able to see what package it was in without installing
anything.

I've already gone ahead and installed some listed in the backup
mentioned and now have that one available but I'd like to know for
future reference if I can determine what fonts are in which packge
somehow.
