If set, vi will first attempt to use the environment variable $EXINIT before
resorting to the .exrc file(s).

Depending upon what I am logged into and where (which machine) I am currently
on, I want to use a different vi initialization file.  (I use this scheme to
try and set every keyboard I work on to function in a similar manner.)  I keep
a set of vi initialization files in the directory $HOME/.misc such as:

	$HOME/.misc/.exrcSUN
	$HOME/.misc/.exrc3B1
	$HOME/.misc/.exrcWY75
	$HOME/.misc/.exrcVT100
	etc.

Here is a skeleton outline from my $HOME/.profile which shows how these files
can be used.  This should give you the general idea of how to set things up.
This scheme has worked just fine for me.  In addition to use in .profile, you
can of course also set and use the EXINIT variable interactively.

Note:  'so' is the ex source command which says to execute the ex commands
	in the named file.


# $HOME/.profile
	...
EDITOR=/usr/bin/vi
	...
case `tty` in
/dev/w*|/dev/syscon)
    EXINIT='so $HOME/.misc/.exrc3B1' ; export EXINIT ;;
/dev/ttyp*)
    case $TERM in
    s4|unixpc)
	EXINIT='so $HOME/.misc/.exrc3B1' ; export EXINIT ;;
    sun)
	EXINIT='so $HOME/.misc/.exrcSUN' ; export EXINIT ;;
    wy75)
	EXINIT='so $HOME/.misc/.exrcWY75' ; export EXINIT ;;
    vt100)
	EXINIT='so $HOME/.misc/.exrcVT100' ; export EXINIT ;;
    *)
	echo ".profile:  Unrecognized terminal type <${TERM}>."
	;;
