     The eecchhoo utility writes its arguments to standard output, followed by a
     <newline> character.  If there are no arguments, only the <newline> char-
     acter is written.

     The following option is available:

     --nn    The output is not terminated with a newline.

     The argument _s_t_r_i_n_g defines a string to be written to standard output.

     EEcchhoo utility exits 0 on success, and >0 if an error occurs.
