then "cd pub" (no quotes, of course)
then "mget *.tar.Z" (no quotes, hit "y" when requested)
then "quit" to close the connection.

There are three compressed tar files, called demon.tar.Z, jobs.tar.Z, and subrs.tar.Z. These should be uncompressed (using the command "uncompress," e.g., uncompress demon. tar).

The following assumes you use an SGI machine. Program modifications may be required if this is not the case and are available on request.

Downloading the program suite DEMON implies the acceptance of the normal rules of conduct concerning freely available software: not to redistribute, patent, or sell the programs; to inform the author of DEMON of any useful modifications, so that these may be made available to the crystallographic community; to properly acknowledge the use of the software suite DEMON in any publications resulting from its use.

A description of the file system used and a handout of a lecture, which is an introduction to the uses of non-crystallographic symmetry averaging, may be obtained from Fred Vellieux, IBS, 41 Ave. des Martyrs, 38027 Grenoble Cedex 01, France. e-mail: velliux@lccp.ibs.fr.
