+/* 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.
+ *
