A random hodge-podge of topics relevant to C25.

• Tidbits on getting started. Trivia like how to start a Lisp interpreter, and how to stop it.
• A Brief History of Common Lisp. Very brief. Uses the same time scale as "A Brief History of Time," so the Lisp part goes by pretty quickly.
• The Lisp Interpreter. How it works. Useful for understanding how macros work.
• require and provide. How require and provide work to load files as needed, in a system-independent way.
• Macros. How to use them, when to use them.
• The Loop Macro (10/9/95). A brief description of the LOOP macro for iteration, covering only those elements provided by xlisp-stat version of loop. The full description is in Steele and Graham.
• Lisp style. Some brief notes on good coding practices.
• Naming. Notes on how to name functions and variables.
