&lt;h2&gt;Installation&lt;/h2&gt;

&lt;p&gt; Here we describe the standard distribution.  If the
standard doesn&#039;t meet your needs, we refer you to the Lua
discussion list, where any question about the package scheme
will likely already have been answered.  &lt;/p&gt;

&lt;h3&gt;Directory structure&lt;/h3&gt;

&lt;p&gt; On Unix systems, the standard distribution uses two base
directories, one for system dependent files, and another for system
independent files. Let&#039;s call these directories &lt;tt&gt;&amp;lt;CDIR&amp;gt;&lt;/tt&gt; 
and &lt;tt&gt;&amp;lt;LDIR&amp;gt;&lt;/tt&gt;, respectively. 
For example, in my laptp, Lua&amp;nbsp;5.1 is configured to
use &#039;&lt;tt&gt;/usr/local/lib/lua/5.1&lt;/tt&gt;&#039; for
&lt;tt&gt;&amp;lt;CDIR&amp;gt;&lt;/tt&gt; and &#039;&lt;tt&gt;/usr/local/share/lua/5.1&lt;/tt&gt;&#039; for
&lt;tt&gt;&amp;lt;LDIR&amp;gt;&lt;/tt&gt;. On Windows, &lt;tt&gt;&amp;lt;CDIR&amp;gt;&lt;/tt&gt;
usually points to the directory where the Lua executable is
found, and &lt;tt&gt;&amp;lt;LDIR&amp;gt;&lt;/tt&gt; points to a
&lt;tt&gt;lua/&lt;/tt&gt; directory inside &lt;tt&gt;&amp;lt;CDIR&amp;gt;&lt;/tt&gt;. (These
settings can be overridden by environment variables 
&lt;tt&gt;LUA_PATH&lt;/tt&gt; and &lt;tt&gt;LUA_CPATH&lt;/tt&gt;. See the Lua
documentation for details.) Here is the standard LuaSocket 
distribution directory structure:&lt;/p&gt;

&lt;pre class=example&gt;
&amp;lt;LDIR&amp;gt;/ltn12.lua
&amp;lt;LDIR&amp;gt;/socket.lua
&amp;lt;CDIR&amp;gt;/socket/core.dll
&amp;lt;LDIR&amp;gt;/socket/http.lua
&amp;lt;LDIR&amp;gt;/socket/tp.lua
&amp;lt;LDIR&amp;gt;/socket/ftp.lua
&amp;lt;LDIR&amp;gt;/socket/smtp.lua
&amp;lt;LDIR&amp;gt;/socket/url.lua
&amp;lt;LDIR&amp;gt;/mime.lua
&amp;lt;CDIR&amp;gt;/mime/core.dll
&lt;/pre&gt;

&lt;p&gt; Naturally, on Unix systems, &lt;tt&gt;core.dll&lt;/tt&gt;
would be replaced by &lt;tt&gt;core.so&lt;/tt&gt;.  
&lt;/p&gt;

&lt;h3&gt;Using LuaSocket&lt;/h3&gt;

&lt;p&gt; With the above setup, and an interpreter with shared library support,
it should be easy to use LuaSocket. Just fire the interpreter and use the
&lt;tt&gt;require&lt;/tt&gt; function to gain access to whatever module you need:&lt;/p&gt;

&lt;pre class=example&gt;
Lua 5.2.2  Copyright (C) 1994-2013 Lua.org, PUC-Rio
&amp;gt; socket = require(&quot;socket&quot;)
&amp;gt; print(socket._VERSION)
--&amp;gt; LuaSocket 3.0.0
&lt;/pre&gt;

&lt;p&gt; Each module loads their dependencies automatically, so you only need to
load the modules you directly depend upon: &lt;/p&gt;

&lt;pre class=example&gt;
Lua 5.2.2  Copyright (C) 1994-2013 Lua.org, PUC-Rio
&amp;gt; http = require(&quot;socket.http&quot;)
&amp;gt; print(http.request(&quot;http://www.impa.br/~diego/software/luasocket&quot;))
--&amp;gt; homepage gets dumped to terminal
&lt;/pre&gt;

&lt;!-- footer +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ --&gt;

&lt;div class=footer&gt;
&lt;hr&gt;
&lt;center&gt;
&lt;p class=bar&gt;
&lt;a href=&quot;index.html&quot;&gt;home&lt;/a&gt; &amp;middot;
&lt;a href=&quot;index.html#down&quot;&gt;download&lt;/a&gt; &amp;middot;
&lt;a href=&quot;installation.html&quot;&gt;installation&lt;/a&gt; &amp;middot;
&lt;a href=&quot;introduction.html&quot;&gt;introduction&lt;/a&gt; &amp;middot;
&lt;a href=&quot;reference.html&quot;&gt;reference&lt;/a&gt;
&lt;/p&gt;
