setting summary buffer color by header/body content

[marklar]

Mutt and pine have facilities for setting the color of the summary
line for each message in the inbox according to text contained in the
header or the body of the message.

For example, a line in muttrc:

color index red green =bVERYBADNEWS

searches the body for the string "VERYBADNEWS" and sets the background
color to red and the foreground to green if it finds the string.

Is there code written for gnus that does the same thing?  I.e. maybe
something from someone's .gnus file?

Thanks,
Marklar
