/* 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.
|
