#
#            Rather like the perl find module, Ruby's find provides an
#            easy way to traverse directories.
#
#            In this example, we traverse the directory structure
#            starting with the current working directory, and count
#            all the files and directories we find.  Just to
#            demonstrate Find.prune(), and make NetApp users happy, we
#            avoid directories named .snapshot.  Note, we "find" the
#            current working directory, so the directory count will
#            always be at least 1.
