   Description: This example demonstrates the use of the match functionality
                within  the  String  Toolkit library.  The  process  takes a
                series of inputs from the  command line and assumes them  to
                be wild-card  patterns. The  process then  proceeds to  read
                input  from  stdin one  line  at a  time,  printing out  the
                patterns that successfully match the current line.

                The  patterns  can  be  constructed  using  either  of   the
                following wild-card characters:

                * : match on zero or more characters ? : match on zero
                or one character

               Example usage:

               ls | ./strtk_glober "*.hpp" "*.cpp" "*.txt" "M?kef*le"
