|
|
|
22 * Program to convert oldstyle goslings emacs mail directories into
|
|
|
23 * gnu-rmail format. Program expects a directory called Messages to
|
|
|
24 * exist in your home directory, containing individual mail messages in
|
|
|
25 * separate files in the standard gosling emacs mail reader format.
|
|
|
26 *
|
|
|
27 * Program takes one argument: an output file. THis file will contain
|
|
|
28 * all the messages in Messages directory, in berkeley mail format.
|
|
|
29 * If no output file is mentioned, messages are put in ~/OMAIL.
|
|
|
30 *
|
|
|
31 * In order to get rmail to read the messages, the resulting file must
|
|
|
32 * be mv'ed to ~/mbox, and then have rmail invoked on them.
