Merge 610bea9c0f into 8c2ff7217e

MinGWs `ws2tcpip.h` already defines `socklen_t`, making this redundant.
What's more, in a recent version of MinGW this has changed to `unsigned int`, breaking compatibility.

-<h2>Installation via luarocks</h2>
+<h2>Installation</h2>
 
+<p> Here we describe the standard distribution.  If the
+standard doesn'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.  </p>
 
+<h3>Directory structure</h3>
 
-<p>LuaSocket can be easily installed using <a href="https://luarocks.org/" target="_blank">LuaRocks</a>, the Lua package manager.</p>
+<p> On Unix systems, the standard distribution uses two base
+directories, one for system dependent files, and another for system
+independent files. Let's call these directories <tt>&lt;CDIR&gt;</tt> 
+and <tt>&lt;LDIR&gt;</tt>, respectively. 
+For example, in my laptp, Lua&nbsp;5.1 is configured to
+use '<tt>/usr/local/lib/lua/5.1</tt>' for
+<tt>&lt;CDIR&gt;</tt> and '<tt>/usr/local/share/lua/5.1</tt>' for
+<tt>&lt;LDIR&gt;</tt>. On Windows, <tt>&lt;CDIR&gt;</tt>
+usually points to the directory where the Lua executable is
+found, and <tt>&lt;LDIR&gt;</tt> points to a
+<tt>lua/</tt> directory inside <tt>&lt;CDIR&gt;</tt>. (These
+settings can be overridden by environment variables 
+<tt>LUA_PATH</tt> and <tt>LUA_CPATH</tt>. See the Lua
+documentation for details.) Here is the standard LuaSocket 
+distribution directory structure:</p>
 
-<h3>Installing via LuaRocks</h3>
-
-<p>Run the following command in your terminal:</p>
 <pre class=example>
-luarocks install luasocket
+&lt;LDIR&gt;/ltn12.lua
+&lt;LDIR&gt;/socket.lua
+&lt;CDIR&gt;/socket/core.dll

+&lt;LDIR&gt;/socket/smtp.lua
+&lt;LDIR&gt;/socket/url.lua
+&lt;LDIR&gt;/mime.lua
+&lt;CDIR&gt;/mime/core.dll
 </pre>
 
-<h3>Verification</h3>
+<p> Naturally, on Unix systems, <tt>core.dll</tt>
-    <p>To verify that LuaSocket is installed correctly, open Lua and run:</p>
+would be replaced by <tt>core.so</tt>.  
-    <pre class=example><code>
+</p>
-   local socket = require("socket")
-   print(socket._VERSION)
-    </code></pre>
 
-<p>If you see output like <strong>LuaSocket 3.0</strong>, the installation was successful.</p>
+<h3>Using LuaSocket</h3>
 
-<h3>More Information</h3>
+<p> With the above setup, and an interpreter with shared library support,
-<p>For more details, visit the <a href="https://github.com/lunarmodules/luasocket" target="_blank">LuaSocket GitHub repository</a>.</p>
+it should be easy to use LuaSocket. Just fire the interpreter and use the

+&gt; socket = require("socket")
+&gt; print(socket._VERSION)
+--&gt; LuaSocket 3.0.0
+</pre>
+
+<p> Each module loads their dependencies automatically, so you only need to
+load the modules you directly depend upon: </p>
+
+<pre class=example>
+Lua 5.2.2  Copyright (C) 1994-2013 Lua.org, PUC-Rio
