+Lua combines simple procedural syntax with powerful data description
+constructs based on associative arrays and extensible semantics.
+Lua is dynamically typed,
+runs by interpreting bytecode with a register-based
+virtual machine,
+and has automatic memory management with
+incremental garbage collection,

+Lua is intended to be used both as a powerful, lightweight,

+it works <em>embedded</em> in a host client,

+(Frequently, this host is the stand-alone <code>lua</code> program.)
The host program can invoke functions to execute a piece of Lua code,
can write and read Lua variables,
and can register C functions to be called by Lua code.
Through the use of C functions, Lua can be augmented to cope with
a wide range of different domains,
thus creating customized programming languages sharing a syntactical framework.
