Add luaproc and LuaJIT libraries.
Two versions of LuaJIT, the stable release, and the dev version. Try the dev version first, until ih fails badly.

63 | LuaJIT has only a single stand-alone executable, called <tt>luajit</tt>. | ||
64 | It can be used to run simple Lua statements or whole Lua applications | ||
65 | from the command line. It has an interactive mode, too. | ||
66 | </p> | ||
67 | <p> | ||
68 | <em>Note: The optimizer is not activated by default because it resides | ||
69 | in an external module | ||
70 | (see <a href="luajit_install.html">Installing LuaJIT</a>). | ||
71 | It's recommended to always use the optimizer, i.e.:</em> <tt>luajit -O</tt> | ||
72 | </p> | ||
73 | |||
74 | <h2 id="options">Command Line Options</h2> | ||
75 | <p> | ||
76 | The <tt>luajit</tt> stand-alone executable is just a slightly modified | ||
77 | version of the regular <tt>lua</tt> stand-alone executable. | ||
78 | It supports the same basic options, too. Please have a look at the | ||
79 | <a href="../doc/lua.html">Manual Page</a> | ||
80 | for the regular <tt>lua</tt> stand-alone executable. | ||
81 | </p> | ||
82 | <p> | ||
83 | Two additional options control LuaJIT behaviour: | ||
84 | </p> | ||
85 | |||
86 | <h3 id="opt_j"><tt>-j cmd[=value]</tt></h3> | ||
87 | <p> | ||
88 | This option performs a LuaJIT control command. LuaJIT has a small | ||
89 | but extensible set of control commands. It's easy to add your own. | ||
90 | </p> | ||
91 | <p> | ||
92 | The command is first searched for in the <tt>jit.*</tt> library. | ||
93 | If no matching function is found, a module named <tt>jit.<cmd></tt> | ||
94 | is loaded. The module table must provide a <tt>start()</tt> function. | ||
95 | </p> | ||
96 | <p> | ||
97 | For the <tt>-j cmd</tt> form the function is called without an argument. | ||
98 | Otherwise the <tt>value</tt> is passed as the first argument (a string). | ||
99 | </p> | ||
100 | <p> | ||
101 | Here are the built-in LuaJIT control commands: | ||
102 | </p> | ||
103 | <ul> | ||
104 | <li id="j_on"><tt>-j on</tt> — Turns the JIT engine on (default).</li> | ||
105 | <li id="j_off"><tt>-j off</tt> — Turns the JIT engine off.</li> | ||
106 | <li id="j_debug"><tt>-j debug[=level]</tt> — Set debug level. See | ||
107 | <a href="luajit_api.html#jit_debug">jit.debug()</a>.</li> | ||
108 | </ul> | ||
109 | <p> | ||
110 | The following control commands are loaded from add-on modules: | ||
111 | </p> | ||
112 | <ul> | ||
113 | <li id="j_trace"><tt>-j trace[=file]</tt> — Trace the progress of the JIT compiler.</li> | ||
114 | <li id="j_dumphints"><tt>-j dumphints[=file]</tt> — Dump bytecode + hints before compilation.</li> | ||
115 | <li id="j_dump"><tt>-j dump[=file]</tt> — Dump machine code after compilation.</li> | ||
116 | </ul> | ||
117 | |||
118 | <!-- | ||
119 | <h3 id="opt_O"><tt>-O[level|ext]</tt></h3> | ||
120 | --> | ||
121 | <h3 id="opt_O"><tt>-O[level]</tt></h3> | ||
122 | <p> | ||
123 | This option loads and runs the optimizer module <tt>jit.opt</tt>. | ||
124 | The optimizer generates hints for the compiler backend to improve | ||
125 | the performance of the compiled code. The optimizer slows down | ||
126 | compilation slightly, but the end result should make up for it | ||
127 | in almost every case. | ||
128 | </p> | ||
129 | <p> | ||
130 | The <tt>-O</tt> form sets the default optimizer level, which is | ||
131 | currently <tt>2</tt> (this may change in future versions | ||
132 | of LuaJIT). | ||
133 | </p> | ||
134 | <p> | ||
135 | The <tt>-Olevel</tt> form explicitly sets the optimizer level: | ||
136 | </p> | ||
137 | <ul> | ||
138 | <li><tt>-O0</tt> — disable the optimizer but leave it attached.</li> | ||
139 | <li><tt>-O1</tt> — perform standard optimizations (like hints for table lookups).</li> | ||
140 | <li><tt>-O2</tt> — like <tt>-O1</tt> but also loads <tt>jit.opt_inline</tt> to enable result hints and inlining for standard library functions.</li> | ||
141 | </ul> | ||
142 | <!-- | ||
143 | <p> | ||
144 | The <tt>-Oext</tt> form loads optimizer extension modules | ||
145 | from <tt>jit.opt_<ext></tt>. | ||
146 | </p> | ||
