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