+-- The path used by `require` to search for a C loader.
+-- Lua initializes the C path `package.cpath` in the same way it initializes
+-- the Lua path `package.path`, using the environment variable `LUA_CPATH`
+-- or a default path defined in `luaconf.h`.
+-- function package.cpath end
+-- * `package.cpath`: package.cpath

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

+-- The path used by `require` to search for a Lua loader.
+-- At start-up, Lua initializes this variable with the value of the environment
+-- variable `LUA_PATH` or with a default path defined in `luaconf.h`, if
+-- the environment variable is not defined. Any "`;;`" in the value of the
+-- environment variable is replaced by the default path.
