How To Write Function Definitions
*********************************

   When the Lisp interpreter evaluates a list, it looks to see whether
the first symbol on the list has a function definition attached to it;
or, put another way, whether the symbol points to a function
definition.  If it does, the computer carries out the instructions in
the definition.  A symbol that has a function definition is called,
simply, a function (although, properly speaking, the definition is the
function and the symbol refers to it.)

Primitive Functions
defun: The `defun' special form.
Install: Install a function definition.
Interactive: Making a function interactive.
Interactive Options: Different options for `interactive'.
Permanent Installation: Installing code permanently.
