/**
* @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
* lang-lsp - FAT 8.3 filename version of lang-lisp.
*
*
* 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.
