| 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 * | |
| 442 | 27 * Program takes one argument: an output file. This file will contain |
| 428 | 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. | |
