Knuth \bigskip\noindent This file may be freely copied and distributed, provided that no changes whatsoever are made. All users are asked to help keep the {\ninett MMIX}ware files consistent and ``uncorrupted,'' identical everywhere in the world. Changes are permissible only if the modified file is given a new name, different from the names of existing files in the {\ninett MMIX}ware package, and only if the modified file is clearly identified as not being part of that package. (The {\ninett CWEB} system has a ``change file'' facility by which users can easily make minor alterations without modifying the master source files in any way. Everybody is supposed to use change files instead of changing the files.) The author has tried his best to produce correct and useful programs, in order to help promote computer science research, but no warranty of any kind should be assumed.}
