  24  * This is a simple program to make a dosified copy of the
  25  * original. That is, it converts unix style line ends to DOS
  26  * style. This is useful for installing text files.
  27  *
  28  * The exact substitution is to replace \n with \r\n. If the line
  29  * already ends with \r\n then it is not changed to \r\r\n.
