/* 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.
 * 
 * Author: Larry Kolodney, 1985

 * RMS, 2 Sept 85: Removed fix maximums on file name sizes.
