                     52: utility reads one or more input text files, and, by
                     53: default, writes the number of lines, words, and bytes
                     54: contained in each input file to the standard output.
                     55: If more than one input file is specified,
                     56: a line of cumulative count(s) for all named files is output on a
                     57: separate line
                     58: following the last file count.
                     59: .Nm Wc
                     60: considers a word to be a maximal string of

                     65: .It Fl c
                     66: The number of bytes in each input file
                     67: is written to the standard output.
                     68: .It Fl l
                     69: The number of lines in each input file
                     70: is written to the standard output.
                     71: .It Fl m
                     72: The number of characters in each input file
                     73: is written to the standard output.
                     74: .It Fl w
                     75: The number of words in each input file

                     83: information requested by that option. The
