=======

   In Lisp, programs (also called "modules", or "libraries") are stored
in files. Each file is a sequence of Lisp forms (known as "top-level
forms"). Most of the top-level forms in a program will be definitions
(i.e. function, macro or variable definitions) since generally each
library is a system of related functions and variables.

   Before the program can be used it has to be "loaded" into the
editor's workspace; this involves reading and evaluating each top-level
form in the file, i.e. instantiating all function definitions, or
whatever.
