18/**
19 * @fileoverview
20 * Registers a language handler for Common Lisp and related languages.
21 *
22 *
23 * To use, include prettify.js and this file in your HTML page.
24 * Then put your code in an HTML tag like
25 *      <pre class="prettyprint lang-lisp">(my lisp code)</pre>
26 * The lang-cl class identifies the language as common lisp.
27 * This file supports the following language extensions:
28 *     lang-cl - Common Lisp
29 *     lang-el - Emacs Lisp
30 *     lang-lisp - Lisp
31 *     lang-scm - Scheme
32 *     lang-lsp - FAT 8.3 filename version of lang-lisp.
33 *
34 *
35 * I used http://www.devincook.com/goldparser/doc/meta-language/grammar-LISP.htm
36 * as the basis, but added line comments that start with ; and changed the atom
37 * production to disallow unquoted semicolons.
38 *
39 * "Name"    = 'LISP'
40 * "Author"  = 'John McCarthy'
41 * "Version" = 'Minimal'
42 * "About"   = 'LISP is an abstract language that organizes ALL'
43 *           | 'data around "lists".'
44 *
45 * "Start Symbol" = [s-Expression]
46 *
47 * {Atom Char}   = {Printable} - {Whitespace} - [()"\'']
48 *
49 * Atom = ( {Atom Char} | '\'{Printable} )+
50 *
51 * [s-Expression] ::= [Quote] Atom
52 *                  | [Quote] '(' [Series] ')'
53 *                  | [Quote] '(' [s-Expression] '.' [s-Expression] ')'
54 *
55 * [Series] ::= [s-Expression] [Series]
56 *            |
57 *
58 * [Quote]  ::= ''      !Quote = do not evaluate
59 *            |
60 *
61 *
62 * I used <a href="http://gigamonkeys.com/book/">Practical Common Lisp</a> as
63 * the basis for the reserved word list.
