	I have been using the new alpha release of Epoch 4.0 for a few days
now and I have some comments to make. Generally speaking, 4.0 is a distinct
improvement over 3.2 and I intend to keep using it unless something
catastrophic happens.

	Highlights

	1) This version appears to be as solid as 3.2 - I have yet to experience
           a core dump.
	2) Epoch 4.0 handles focus-in and focus-out events properly - fixing
	   one of the major complaints about 3.2!
	3) Selections between Epoch and other X clients (esp. xterm) is now
	   handled properly - fixing the other major complaint re: 3.2.

	4) Mouse-based cut and paste (and selection highlighting) is great!
	5) Being able to have a mini-buffer in a screen (instead of as a
	   separate screen) fixes problems using Epoch with tvtwm or other
	   virtual window managers.

	Problems

	1) When building and installing (I used the build-install script), it
	   took me several tries before I could figure out why the temacs
	   dump process couldn't find any of the epoch-lisp files when it
	   appeared to be able to find the regular lisp files. I had to fix
	   the sed command in the build-install script to do a global replace
	   on paths.h so the second element of the load-path was modified as
	   well. I believe my final solution (the one that worked) was to
	   unsetenv my EMACSLOADPATH environment variable so that temacs would
	   only look in the $BUILD directory - there should be instructions
	   on how to do this.

	2) When running (the newest version of) gdb, Epoch (4.0) seemed to have
	   trouble maintaining proper concordance between the gdb command buffer
	   and the => in the current source listing buffer. It would frequently
	   lose the = part of the => position arrow or lose synchronization
	   completely for a period of time.

	3) There is no indication in the instructions that it is no longer
	   necessary to load the epoch-lisp files in the .emacs file. This
	   means that an error in init file occurs when Epoch is first brought
	   up.

	4) Neither server.el nor gnuserv (from the contrib directory) work
	   with 4.0 - gnuserv is based on 3.2 and the changes in x11fns.c were
	   too extensive for me to quickly figure out how to fix the patch.
	   server.el is the original emacs version, not even the epoch 3.2
	   version.

Thanks for the comments.  many of the problems you mention with 4.0 are
fixed in the first patchlevel release, which will be announced "soon"
(please dont ask, we'll let you all know when it is ready.

the build problems seem unusual.  It works OK for us.  some problems were
reported because of a .h dependency on a file that has been removed from
the distribution, but not failing to find the epoch-lisp files.  if you
could provide more info (e.g. machine type, OS etc) it would help

not having to load the epoch-lisp files has been the case since 3.2, I
believe, but perhaps in 3.2 it didnt matter.  We should mention that in the
docs/installation files. thanks.

more generally:  please send comments/criticisms to
epoch-design@cs.uiuc.edu, rather than the regular epoch list or group, as
we are trying to keep traffic about 4.0a off the regular list until it
"matures" some more.  The epoch-design list is open to anyone who wishes to
join, send email to epoch-design-request@cs.uiuc.edu.  

cheers
Simon
