This example prompts the user for addresses needed in the message
envelope (`To' and `From' addresses), and the message to be
delivered.  Note that the headers to be included with the message must 
be included in the message as entered; this example doesn't do any
processing of the RFC 822 
 headers.  In particular, the `To' and
`From' addresses must be included in the message headers explicitly.
