+ * @fileoverview
+ * Registers a language handler for Common Lisp and related languages.
+ *
+ *
+ * To use, include prettify.js and this file in your HTML page.
+ * Then put your code in an HTML tag like
+ * <pre class="prettyprint lang-lisp">(my lisp code)</pre>
+ * The lang-cl class identifies the language as common lisp.
+ * This file supports the following language extensions:
+ * lang-cl - Common Lisp
+ * lang-el - Emacs Lisp
+ * lang-lisp - Lisp
+ * lang-scm - Scheme
+ *
+ *
+ * I used http://www.devincook.com/goldparser/doc/meta-language/grammar-LISP.htm
+ * as the basis, but added line comments that start with ; and changed the atom
+ * production to disallow unquoted semicolons.
+ *
+ * "Name" = 'LISP'
+ * "Author" = 'John McCarthy'
+ * "Version" = 'Minimal'
+ * "About" = 'LISP is an abstract language that organizes ALL'
+ * | 'data around "lists".'
+ *
+ * "Start Symbol" = [s-Expression]
+ *
+ * {Atom Char} = {Printable} - {Whitespace} - [()"\'']
+ *
+ * Atom = ( {Atom Char} | '\'{Printable} )+
+ *
+ * [s-Expression] ::= [Quote] Atom
+ * | [Quote] '(' [Series] ')'
+ * | [Quote] '(' [s-Expression] '.' [s-Expression] ')'
+ *
+ * [Series] ::= [s-Expression] [Series]
+ * |
+ *
+ * [Quote] ::= '' !Quote = do not evaluate
+ * |
+ *
+ *
+ * I used <a href="http://gigamonkeys.com/book/">Practical Common Lisp</a> as
+ * the basis for the reserved word list.
+ *
