+A number of different fields in the above configuration files support a simple
+form of wildcard matching.  This form is based on the fnmatch(3) style, and
+supports the following fields:
+.RS
+.TP
+.B *
+Matches zero, one, or more characters.
+.TP
+.B ?
+Matches any single character, but does not match zero characters.
+.TP
+.B [ ]
+Matches any single character specified within the brackets. For example, the
+pattern string "tty[SR]" would match either "ttyS" or "ttyR".  Ranges are also
+supported within this match with the '-' character.  For example, to match on
+the range of all digits, the pattern [0-9] would be used.
