I don't like legalese, so here I'll give a history of hey & it's various authors
(as far as I've traced it back, that is; if anyone can fill me in on anything 
I'm missing let me know). 

The first version I know of was written in Perl by Adrian Colley, at TCD. I 
know nothing more about him, except that he was a friend of Paul McGaley, who 
took over it next. Later, in DCU, another version was written by Adam Kelly, 
Colin Whittaker & David Madden. At this point, it was noticed that many a perl 
interpreter had to start for people to send heys back and forth, and so I 
figured it was worth a rewrite in C. c-hey's options and environment variables 
are taken from the Adam & Co. version.

Small ChangeLog:

1.2:
	Readline support was added by Robert Crosbie <bobb@redbrick.dcu.ie>.

1.3:
	Support for heying from a mesg n terminal was added by Colm Mac Cárthaigh 
	<colmmacc@redbrick.dcu.ie>.

1.4:
	hey now issues a warning if there are no valid recipients
	hey now initialises readline properly so that rl_readline_name="hey";
	allowing $if "hey": constructs in the .inputrc

	A va_arg macro portability problem was fixed.

	An install tab was added to the makefile.

	autoconf support was enhanced, the configure script now
	searches for the correct compiler (and settings), install
	utility and system libraries.

	c-hey is now pretty portable ;)
	<colmmacc@redbrick.dcu.ie>.

1.5:
	extra warning "feature" from 1.4 removed

	x@rb's prompt patch for c-hey was rolled in to the main source
		- ability to have customisable prompts now possible
		- added -n option, because ppl like different lengths

	added specific eof support, a string can now be used to determine
	EOF instead of the standard unix way of doing things, this makes
	it easier for mac users .. apparantly!

	added much better handling of being switched between background and
	foreground, c-hey now refreshes your screen so you can more easily
	take up where you left off :)

	make install depend on "stripped"

	fixed gcc3.0 warnings
	<colmmacc@redbrick.dcu.ie>

2.0:
	screen handling was added, to allow multi-line editing
 	this is one BIG change :)
		- includes bindable readline functions, with sane
		  defaults
		- refresh on ctrl-l , for interrupted heys
	
	dependencies in Makefile.in now come from gcc -MM

	cleaned up the configure script a little
	<colmmacc@redbrick.dcu.ie>


-------------------------------------------------------------------------------

So there you go. If you like hey, let me know where you're using it so that I 
can massage my ego. Thanks
