/* 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
1989-10-31 16:00:11 +00:00
* 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.
