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