	This program is based loosely on a mail program called
"xlview", which is again based on an earlier program called
"ximap". While portions of the source code are derived in part from
the earlier works, it is a total rewrite.

	To give credit where credit is due, the original ximap program
was authored by Kevin Brock, under a research grant at the Center
for Advanced Medical Informatics At Stanford (CAMIS) and under the
direction of the Symbolic Systems Resources Group (SSRG). 

	Bill Yeager and I took over development a few years back
and turned it into xlview, which was as far as I know, the first
implementation of active mailbox filtering in a mail user agent
(MUA). It is now quite a popular concept. Bill Yeager is reponsible
for making all of the "logical view" code work, much of which is still
intact in the current program -- with only slight alteration to account
for different data structures.

	Additionally, we have had some other workers on the project
over the years, notably Lilly Shieh and Mary Pawelko, whose work
showed up in the original address book implementation. Not much of
this code survived, but I would like to acknowledge their ideas, and
although implemented differently, the basic concepts are mostly
theirs.

	Outside contributions include:

	Rich Salz (UUnet) for Unix wildcard matching functions.
	Nathenial Borenstein (Bellcore Labs) for MIME handler parsing.
	Mark Crispin (University of Washington) for the IMAP c-client.
	Phil Zimmerman (and RSA, and MIT, etc.) for PGP, which I've
		tied into at the application shell level.

	If I have left anybody out, it is not intentional. All complex
software works are built on the efforts of all those who came before,
be it the OS developers, the window system developers, those that
defined the standards of mail interchange; etc. I am deeply indebted
to all of them.
