<h2><a name="overview"></a>Overview</h2>
<p>LuaFileSystem is a <a href="http://www.lua.org">Lua</a> library
developed to complement the set of functions related to file
systems offered by the standard Lua distribution.</p>
<p>LuaFileSystem offers a portable way to access
the underlying directory structure and file attributes.</p>
<p>LuaFileSystem is free software and uses the same
<a href="license.html">license</a> as Lua 5.x (MIT).</p>
<h2><a name="status"></a>Status</h2>
<p>Current version is 1.8.0. It works with Lua 5.1, 5.2, 5.3 and 5.4, and it runs on various
flavors of Unix (including Linux, BSDs, macOS) and Windows.</p>
<h2><a name="download"></a>Download</h2>
<p>LuaFileSystem can be installed using <a href="https://luarocks.org">LuaRocks</a>:
<pre class="example">
$ luarocks install luafilesystem
</pre>
<p>Its source can be found at its <a href="http://github.com/keplerproject/luafilesystem">GitHub</a> page.</p>
