 SWIG is very broadly composed of two components.
-A core component creates a parse tree from the input C/C++ and SWIG directives (extensions to C/C++).
+A core component creates a parse tree from the input ISO C/C++ and SWIG directives (extensions to the C/C++ standards).
 The parse tree is then passed to a second component, one of the target language modules for generating code specific to a higher level language.
 SWIG supports many different target languages.
 These target languages are given a status of either Supported or Experimental.

 extremely conservative approach to code generation. At its core, SWIG

-Lua is an extension programming language designed to support general procedural programming with data description facilities. It also offers good support for object-oriented programming, functional programming, and data-driven programming. Lua is intended to be used as a powerful, light-weight configuration language for any program that needs one. Lua is implemented as a library, written in clean C (that is, in the common subset of ANSI C and C++). It's also a <em>really</em> tiny language, less than 6000 lines of code, which compiles to &lt;100 kilobytes of binary code. It can be found at <a href="http://www.lua.org">http://www.lua.org</a>

 eLua stands for Embedded Lua (can be thought of as a flavor of Lua) and offers the full implementation of the Lua programming language to the embedded world, extending it with specific features for efficient and portable software embedded development. eLua runs on smaller devices like microcontrollers and provides the full features of the regular Lua desktop version.
