-<h2>5.3 - <a name="5.3">Modules</a></h2>
-
-<p>
-The package library provides basic
-facilities for loading and building modules in Lua.
-It exports two of its functions directly in the global environment:
-<a href="#pdf-require"><code>require</code></a> and <a href="#pdf-module"><code>module</code></a>.
-Everything else is exported in a table <a name="pdf-package"><code>package</code></a>.
-
-
-<p>
-<hr><h3><a name="pdf-module"><code>module (name [, &middot;&middot;&middot;])</code></a></h3>
-
-
-<p>
-Creates a module.
-If there is a table in <code>package.loaded[name]</code>,
-this table is the module.
-Otherwise, if there is a global table <code>t</code> with the given name,
-this table is the module.
-Otherwise creates a new table <code>t</code> and
-sets it as the value of the global <code>name</code> and
-the value of <code>package.loaded[name]</code>.
-This function also initializes <code>t._NAME</code> with the given name,
-<code>t._M</code> with the module (<code>t</code> itself),
-and <code>t._PACKAGE</code> with the package name
-(the full module name minus last component; see below).
-Finally, <code>module</code> sets <code>t</code> as the new environment
-of the current function and the new value of <code>package.loaded[name]</code>,
-so that <a href="#pdf-require"><code>require</code></a> returns <code>t</code>.
-
-
-<p>
-If <code>name</code> is a compound name
-(that is, one with components separated by dots),
-<code>module</code> creates (or reuses, if they already exist)
-tables for each component.
-For instance, if <code>name</code> is <code>a.b.c</code>,
-then <code>module</code> stores the module table in field <code>c</code> of
-field <code>b</code> of global <code>a</code>.
-
-
-<p>
-This function can receive optional <em>options</em> after
-the module name,
-where each option is a function to be applied over the module.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-require"><code>require (modname)</code></a></h3>
-
-
-<p>
-Loads the given module.
-The function starts by looking into the <a href="#pdf-package.loaded"><code>package.loaded</code></a> table
-to determine whether <code>modname</code> is already loaded.
-If it is, then <code>require</code> returns the value stored
-at <code>package.loaded[modname]</code>.
-Otherwise, it tries to find a <em>loader</em> for the module.
-
-
-<p>
-To find a loader,
-<code>require</code> is guided by the <a href="#pdf-package.loaders"><code>package.loaders</code></a> array.
-By changing this array,
-we can change how <code>require</code> looks for a module.
-The following explanation is based on the default configuration
-for <a href="#pdf-package.loaders"><code>package.loaders</code></a>.
-
-
-<p>
-First <code>require</code> queries <code>package.preload[modname]</code>.
-If it has a value,
-this value (which should be a function) is the loader.
-Otherwise <code>require</code> searches for a Lua loader using the
-path stored in <a href="#pdf-package.path"><code>package.path</code></a>.
-If that also fails, it searches for a C&nbsp;loader using the
-path stored in <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
-If that also fails,
-it tries an <em>all-in-one</em> loader (see <a href="#pdf-package.loaders"><code>package.loaders</code></a>).
-
-
-<p>
-Once a loader is found,
-<code>require</code> calls the loader with a single argument, <code>modname</code>.
-If the loader returns any value,
-<code>require</code> assigns the returned value to <code>package.loaded[modname]</code>.
-If the loader returns no value and
-has not assigned any value to <code>package.loaded[modname]</code>,
-then <code>require</code> assigns <b>true</b> to this entry.
-In any case, <code>require</code> returns the
-final value of <code>package.loaded[modname]</code>.
-
-
-<p>
-If there is any error loading or running the module,
-or if it cannot find any loader for the module,
-then <code>require</code> signals an error.

-it initializes the Lua path <a href="#pdf-package.path"><code>package.path</code></a>,

-When you require a module <code>modname</code> and

-<hr><h3><a name="pdf-package.loaders"><code>package.loaders</code></a></h3>
-
-
-<p>
-A table used by <a href="#pdf-require"><code>require</code></a> to control how to load modules.
-
-
-<p>
-Each entry in this table is a <em>searcher function</em>.
-When looking for a module,
-<a href="#pdf-require"><code>require</code></a> calls each of these searchers in ascending order,
-with the module name (the argument given to <a href="#pdf-require"><code>require</code></a>) as its
-sole parameter.
-The function can return another function (the module <em>loader</em>)
-or a string explaining why it did not find that module
-(or <b>nil</b> if it has nothing to say).
-Lua initializes this table with four functions.
-
-
-<p>
-The first searcher simply looks for a loader in the
-<a href="#pdf-package.preload"><code>package.preload</code></a> table.
-
-
-<p>
-The second searcher looks for a loader as a Lua library,
-using the path stored at <a href="#pdf-package.path"><code>package.path</code></a>.
-A path is a sequence of <em>templates</em> separated by semicolons.
-For each template,
-the searcher will change each interrogation
-mark in the template by <code>filename</code>,
-which is the module name with each dot replaced by a
-"directory separator" (such as "<code>/</code>" in Unix);
-then it will try to open the resulting file name.
-So, for instance, if the Lua path is the string
-
-<pre>
-     "./?.lua;./?.lc;/usr/local/?/init.lua"
-</pre><p>
-the search for a Lua file for module <code>foo</code>
-will try to open the files
-<code>./foo.lua</code>, <code>./foo.lc</code>, and
-<code>/usr/local/foo/init.lua</code>, in that order.
-
-
-<p>
-The third searcher looks for a loader as a C&nbsp;library,
-using the path given by the variable <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
-For instance,
-if the C&nbsp;path is the string
-
-<pre>
-     "./?.so;./?.dll;/usr/local/?/init.so"
-</pre><p>
-the searcher for module <code>foo</code>
-will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>,
-and <code>/usr/local/foo/init.so</code>, in that order.
-Once it finds a C&nbsp;library,
-this searcher first uses a dynamic link facility to link the
-application with the library.
-Then it tries to find a C&nbsp;function inside the library to
-be used as the loader.
-The name of this C&nbsp;function is the string "<code>luaopen_</code>"
-concatenated with a copy of the module name where each dot
-is replaced by an underscore.
-Moreover, if the module name has a hyphen,
-its prefix up to (and including) the first hyphen is removed.
-For instance, if the module name is <code>a.v1-b.c</code>,
-the function name will be <code>luaopen_b_c</code>.
-
-
-<p>
-The fourth searcher tries an <em>all-in-one loader</em>.
-It searches the C&nbsp;path for a library for
-the root name of the given module.
-For instance, when requiring <code>a.b.c</code>,
-it will search for a C&nbsp;library for <code>a</code>.
-If found, it looks into it for an open function for
-the submodule;
-in our example, that would be <code>luaopen_a_b_c</code>.
-With this facility, a package can pack several C&nbsp;submodules
-into one single library,
-with each submodule keeping its original open function.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.loadlib"><code>package.loadlib (libname, funcname)</code></a></h3>
-
-
-<p>
-Dynamically links the host program with the C&nbsp;library <code>libname</code>.
-Inside this library, looks for a function <code>funcname</code>
-and returns this function as a C&nbsp;function.
-(So, <code>funcname</code> must follow the protocol (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>)).
-
-
-<p>
-This is a low-level function.
-It completely bypasses the package and module system.
-Unlike <a href="#pdf-require"><code>require</code></a>,
-it does not perform any path searching and
-does not automatically adds extensions.
-<code>libname</code> must be the complete file name of the C&nbsp;library,
-including if necessary a path and extension.
-<code>funcname</code> must be the exact name exported by the C&nbsp;library
-(which may depend on the C&nbsp;compiler and linker used).
-
-
-<p>
-This function is not supported by ANSI C.
-As such, it is only available on some platforms

-<h1>7 - <a name="7">Incompatibilities with the Previous Version</a></h1>
-
-<p>
-Here we list the incompatibilities that you may find when moving a program
-from Lua&nbsp;5.0 to Lua&nbsp;5.1.
-You can avoid most of the incompatibilities compiling Lua with
-appropriate options (see file <code>luaconf.h</code>).
-However,
-all these compatibility options will be removed in the next version of Lua.
-
-
-
-<h2>7.1 - <a name="7.1">Changes in the Language</a></h2>
-<ul>
-
-<li>
-The vararg system changed from the pseudo-argument <code>arg</code> with a
-table with the extra arguments to the vararg expression.
-(See compile-time option <code>LUA_COMPAT_VARARG</code> in <code>luaconf.h</code>.)
-</li>
-
-<li>
-There was a subtle change in the scope of the implicit
-variables of the <b>for</b> statement and for the <b>repeat</b> statement.
-</li>
-
-<li>
-The long string/long comment syntax (<code>[[<em>string</em>]]</code>)
-does not allow nesting.
-You can use the new syntax (<code>[=[<em>string</em>]=]</code>) in these cases.
-(See compile-time option <code>LUA_COMPAT_LSTR</code> in <code>luaconf.h</code>.)
-</li>
-
-</ul>
-
-
-
-
-<h2>7.2 - <a name="7.2">Changes in the Libraries</a></h2>
-<ul>
-
-<li>
-Function <code>string.gfind</code> was renamed <a href="#pdf-string.gmatch"><code>string.gmatch</code></a>.
-(See compile-time option <code>LUA_COMPAT_GFIND</code> in <code>luaconf.h</code>.)
-</li>
-
-<li>
-When <a href="#pdf-string.gsub"><code>string.gsub</code></a> is called with a function as its
-third argument,
-whenever this function returns <b>nil</b> or <b>false</b> the
-replacement string is the whole match,
-instead of the empty string.
-</li>
-
-<li>
-Function <code>table.setn</code> was deprecated.
-Function <code>table.getn</code> corresponds
-to the new length operator (<code>#</code>);
-use the operator instead of the function.
-(See compile-time option <code>LUA_COMPAT_GETN</code> in <code>luaconf.h</code>.)
-</li>
-
-<li>
-Function <code>loadlib</code> was renamed <a href="#pdf-package.loadlib"><code>package.loadlib</code></a>.
-(See compile-time option <code>LUA_COMPAT_LOADLIB</code> in <code>luaconf.h</code>.)
-</li>
-
-<li>
-Function <code>math.mod</code> was renamed <a href="#pdf-math.fmod"><code>math.fmod</code></a>.
-(See compile-time option <code>LUA_COMPAT_MOD</code> in <code>luaconf.h</code>.)
-</li>
-
-<li>
-Functions <code>table.foreach</code> and <code>table.foreachi</code> are deprecated.
-You can use a for loop with <code>pairs</code> or <code>ipairs</code> instead.
-</li>
-
-<li>
-There were substantial changes in function <a href="#pdf-require"><code>require</code></a> due to
-the new module system.
-However, the new behavior is mostly compatible with the old,
-but <code>require</code> gets the path from <a href="#pdf-package.path"><code>package.path</code></a> instead
-of from <code>LUA_PATH</code>.
-</li>
-
-<li>
-Function <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> has different arguments.
-Function <code>gcinfo</code> is deprecated;
-use <code>collectgarbage("count")</code> instead.
-</li>
-
-</ul>
-
-
-
-
-<h2>7.3 - <a name="7.3">Changes in the API</a></h2>
-<ul>
-
-<li>
-The <code>luaopen_*</code> functions (to open libraries)
-cannot be called directly,
-like a regular C function.
-They must be called through Lua,
-like a Lua function.
-</li>
-
-<li>
-Function <code>lua_open</code> was replaced by <a href="#lua_newstate"><code>lua_newstate</code></a> to
-allow the user to set a memory-allocation function.
-You can use <a href="#luaL_newstate"><code>luaL_newstate</code></a> from the standard library to
-create a state with a standard allocation function
-(based on <code>realloc</code>).
-</li>
-
-<li>
-Functions <code>luaL_getn</code> and <code>luaL_setn</code>
-(from the auxiliary library) are deprecated.
-Use <a href="#lua_objlen"><code>lua_objlen</code></a> instead of <code>luaL_getn</code>
-and nothing instead of <code>luaL_setn</code>.
-</li>
-
-<li>
-Function <code>luaL_openlib</code> was replaced by <a href="#luaL_register"><code>luaL_register</code></a>.
-</li>
-
-<li>
-Function <code>luaL_checkudata</code> now throws an error when the given value
-is not a userdata of the expected type.
-(In Lua&nbsp;5.0 it returned <code>NULL</code>.)
