                                  public.c

For public access ...

Displays a list of messages in a folder.
Displays the contents of a message (header, body, links to attachments).
Displays a 'print-view' (more suitable for printing) of a message.
Displays the raw message (header+body, or header alone).

Of course with limitations and in a format that is suitable for public access!
