  19:  * Program to convert oldstyle goslings emacs mail directories into
  20:  * gnu-rmail format.  Program expects a directory called Messages to
  21:  * exist in your home directory, containing individual mail messages in
  22:  * separate files in the standard gosling emacs mail reader format.
  23:  *
  24:  * Program takes one argument: an output file.  THis file will contain
  25:  * all the messages in Messages directory, in berkeley mail format.
  26:  * If no output file is mentioned, messages are put in ~/OMAIL.
  27:  *
  28:  * In order to get rmail to read the messages, the resulting file must
  29:  * be mv'ed to ~/mbox, and then have rmail invoked on them.
