Hi there,
	I'm not a usual reader of comp.lang.prolog but I have a problem I'm
sure many readers of this newsgroup can help me with.  I'm currently working
on a committee here in the CS dept. at the University of Virginia which is
involved in the evaluation/renovation of the department's infrastructure.  My
task is to propose a prolog system which will support research (primarily).
The system is to run on Unix based Sun workstations and hopefully support
X windows.
	What I'm hoping some of you could do is send me some e-mail with your
favorite prolog system which meets the above requirements.  I would also
appreciate it if you could tell me what you like about the system and also
any drawbacks the system might have (if it has any, of course :^).  I've
heard some good things about the Quintus sytem and would appreciate any
good/bad/impartial feedback that might be offered.
	Sorry to waste bandwidth with my petty plea, but my prolog experience
is limited to pc-based Turbo prolog and this doesn't help me much.  Again,
any and/or all responses would be GREATLY appreciated.  Thanks in advance!!!
