PGPcompose 1.0
(c) 1993 Nate Sammons

PGPcompose is a C program (that needs to be compiled, oddly enough)
that is designed to allow for easy incorporation of digital 
signatures and encryption with PGP (from Phil Zimmerman).

It may be necessary to change some of the calls within PGPcompose,
so that it will access the right mailer (it is set to /usr/lib/sendmail)
etc...  It should be placed somewhere in your path, or that you
modify your path (in ~/.cshrc) so that it is.

I plan to expand PGPcompose's abilities so that it will be a complete
mailer package ready for use...  hopefully!  I want to add support for
replys and for mail management.

BTW, this software carries no warranty, and if in the use of it you 
break something, it's not my fault (this for all you legaleese-speakers
out there...)
