  Purpose:

    CR2LF replaces carriage returns by line feeds.

  Discussion:

    This simple-minded program reads each character in a text file,
    and replaces every carriage return character by a line feed
    character.

    Note that the output of GETCHAR is an INT, and not a CHAR, and
    we need to honor this so that we can catch EOF, which is equal to
    -1.

  Sample usage:

    cr2lf < infile > outfile
