21 | /* cvtmail: | |
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 | * | |
231c740a | 27 | * Program takes one argument: an output file. This file will contain |
518dd722 JB |
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. | |
