      1  /*
      2   *	This program strips the CRs from a file.  MSDOS uses CRLF for
      3   * \n while Unix uses only a LF.  In addition, ^Z characters are
      4   * stripped from the input file.  Unix does not use ^Z to mark the
      5   * EOF, while some MSDOS editors put a ^Z at the end of a file.
      6   * ^D characters are stripped from the file also.  Some PC products
      7   * which produce Postscript output put ^Ds in the file.  Some
      8   * Postscript printers will complain about these files and refuse
      9   * to print them.
