+may be provided as a basic or extended regular expression, or as fixed
+strings.  By default, the matching text is simply printed to the screen,
+however the output can be greatly customized to include, for example, line
+numbers.  GNU grep offers many extensions over the standard utility,
+including, for example, recursive directory searching.")
