The reference manual

The eLua reference manual presents in details all the modules that can be used from a Lua program running inside eLua. It doesn't cover the standard Lua libraries, as the Lua reference manual already does a very good job at this. Instead, it covers eLua-specific modules (most of which are linked with the platform interface) and some generic "3rd party" modules that are included in eLua by default. There are two types of modules in eLua, both of which are presented in this section:

• generic modules: they are available on all platforms and should behave the same on all platforms.
• platform-dependent modules: they can be found only on specific platforms. Using them sacrifices portability, but gives access to platform internals that aren't covered by the generic modules (for example specific hardware features).

Remember that in order to use a module (generic or not) in eLua you must first include it in your eLua binary image, check here for instructions on how to do this.
