Here are some notes on installing the
Spice and Magic programs contained in the files
spice.tar.gz and caddirs.tar.gz respectively.

1)  Become 'super-user' (type 'su' and then enter the root
    password).  Then move to the directory /usr/local

           cd /usr/local

2)  Ftp the files spice.tar.gz and caddirs.tar.gz from the
    class web site into /usr/local.

    Make sure you use binary mode in doing the ftp
    (type 'bin' before typing 'get ...').

3)  Unzip each file using 'gunzip <filename>'.  You should
    be left with two .tar files.

4)  The file spice.tar contains spice3 and the associated
     directories and help files.  To install it, make sure
     you are still in /usr/local and then do

             tar xvf spice.tar

    This should create a new directory called spice in /usr/local.
    Just to be safe, set the permissions on this new directory
    using
             chmod 755 spice

5)  The file caddirs.tar contains magic and all of its associated
    files and directories.  To install this one, you will need
    to create a 'cad' subdirectory in /usr/local if one does not
    already exist, and move the caddirs.tar file there:

                    mkdir cad
                    chmod 755 cad
                    cd cad
                    mv ../caddirs.tar .

6)  Untar the caddirs.tar file in this directory

        tar xvf caddirs.tar

    This should create several subdirs such as bin, lib, etc.

7)  Leave superuser mode
         exit

8)  Edit your .cshrc or .tcshrc (or whatever shell you use) file
    to include the environment variables and path info needed.

    Add the following to path:
      /usr/local/spice/bin
      /usr/local/cad/bin

    Add the following to MANPATH
      /usr/local/cad/man

    Add the following environment vars:
      CAD_HOME /usr/local/cad

9)  Create a new xterm so the edits in step 8 take effect.
    Then try it out!

************  IMPORTANT NOTE  ************************

There may still be some export restrictions on spice (but I
doubt it).  Just to be safe, don't ship it out of the country.
