Locians, I have seen a few programs that let you make a simple GUI front end for command-line programs. A good one, of course, would even have a "wizard" to help you. Here is one: http://www.fortunecity.com/skyscraper/java/714/ggui/ There was another one called "Gufe", but it seems to have disappeared. I would like to have something like this for configuring Loci to work with command-line programs. A wizard would be helpful for even the author of a program. Jeff -- J.W.
