.TL A System for Automatic Software Distribution .AU Mike Haertel .AI AT&T Bell Laboratories Murray Hill, NJ 07974 .AB .\" .\" Single Heterogeneous network seeks automatic software distribution mechanism .\" \(em Greg Lindahl .\" With the advent of wildly heterogeneous networks, automatic software distribution has become a nightmare. Binaries are useless, and source code often fails to recompile across ostensibly standard systems. Finally, security is, as always, a concern, especially when the automatic installation of priviliged system software is desired. We describe yet another attempt to address some of these issues. Our system is built out of the .UX tools, with a small amount of glue. .AE
