Well, here is the answer. You use them as input to a program called mkpath. The output of mkpath is a list of sites and a printf-type string that shows the shortest path to the site. There are several options to mkpath, one to select the starting point, one to force all connections to be two-way, one to delete an arbitrary site or connection, and one to add a connection. This program runs under V7 UN*X or 4.1BSD with no modifications. Our PDP-11/60 (non split I/D) took two minutes to run through the data, so a VAX will be somewhat faster. What do you do with the output of mkpath? Simple - you use it as input to a program called nmail! Nmail takes as arguments the mail address of who you'd like to send mail to. It strips everything up to the first '!', and replaces the rest by using the printf string for the site described by the address up to the first '!'. It then exec's the normal mailer, passing it the new arguments. How do I get my copy? You take it off net.sources. The programs plus their manual pages will be sent down net.sources shortly. If you have any questions/comments, send them to: Mike Mitchell decvax!duke!mcnc!ikonas!mcm Better yet, use the mkpath and nmail, and just say ikonas!mcm. Mike Mitchell
