Assignment 5 is designed to introduce you to LISP. 

Some information to help you understand the Given: 

In the main directory:

    test.l	
	contains test functions for every function you are required to 
	write for this assignment. Be sure to ***READ THE COMMENTS***
	in that file which will provide you some useful information,
	especially about differences in output format.

    init.lsp  
	used to load programs

In each part directory:

    Output.correct 
	the correct output

    s.l Work on this file ONLY.  (It's not actually "given"; you need
	to create it.)  Place all your functions in this file, as this
	is loaded by "init.lsp".


As you did on the previous assignment, you'll be using the tester tool
for testing.  To test everything after you've implemented all your
functions, all you need to do is (within a part directory):

  ../tester

That will run your code in `batch" mode and "diff" its output with the
correct output.  Comments in the test.l tell you how to run your code
interactively, which can be helpful in debugging (e.g., to use trace,
etc.).

When you're done with one part, copy s.l to the next part and start
work there.

To test all parts, within the main directory, just use:

  ./tester
