 <p>Lua is one of the simplest languages available, but Luan is even simpler.  This means Luan removes more than it adds.  Most of what is added is added in the library, not in the language itself.</p>
 
 <p>Luan is implemented in Java and is tightly integrated with Java.  This makes it an excellent scripting language for Java.</p>
