CS411 Downloadable Source and Executables

  These files should be downloaded, only some may be viewed.
  In Netscape this may be  RIGHT CLICK  rather than left click.

  You may also be able to ftp some of the files:
    from  retriever.cs.umbc.edu/~squire/www/download
    and some from  irix.gl.umbc.edu/afs/umbc.edu/users/s/q/squire/pub
    and subdirectory /linux/redhat52  for Linux executable
