Picon Basics
------------
What are Picons? To quote directly from the Picons Web site
(`http://www.cs.indiana.edu/picons/ftp/index.html'):
"Picons" is short for "personal icons". They're small,
constrained images used to represent users and domains on the net,
organized into databases so that the appropriate image for a given
e-mail address can be found. Besides users and domains, there are
picon databases for Usenet newsgroups and weather forecasts. The
picons are in either monochrome `XBM' format or color `XPM' and
`GIF' formats.
Please see the above mentioned web site for instructions on obtaining
and installing the picons databases, or the following ftp site:
`http://www.cs.indiana.edu/picons/ftp/index.html'.
Gnus expects picons to be installed into a location pointed to by
`gnus-picons-database'.
