   1 * Introduction  -*-grep-*-
   2
   3 This shows the different kinds of messages grep recognizes by default and
   4 how they are rendered.  It is intended both to help you decide which matchers
   5 you need and as a test of the matchers.  Move the mouse over a colored part
   6 to see how much text was actually matched.
