* What is Lua?
Lua is a programming language originally designed for extending applications,
but also frequently used as a general-purpose, stand-alone language.
Lua combines simple procedural syntax (similar to Pascal) with powerful
data description constructs based on associative arrays and extensible
semantics. Lua is dynamically typed, interpreted from bytecodes, and has
automatic memory management, making it ideal for configuration, scripting,
and rapid prototyping.
Lua is implemented as a small library of C functions, written in ANSI C,
and compiles unmodified in all known platforms. The implementation goals
are simplicity, efficiency, portability, and low embedding cost.
Lua was awarded the first prize (technological category) in the Second Compaq
Award for Research and Development in Computer Science in 1997. This award
is a joint venture of Compaq Computer in Brazil, the Brazilian Ministry of
Science and Technology, and the Brazilian Academy of Sciences.
Lua has been used in many different projects around the world.

* New in version 3.2
+ redirected all output in Lua's core to _ERRORMESSAGE and _ALERT.
+ increased limit on the number of constants and globals per function
(from 2^16 to 2^24).
+ debugging info (lua_debug and hooks) moved into lua_state and new API
functions provided to get and set this info.
+ new debug lib gives full debugging access within Lua.
+ new table functions "foreachi", "sort", "tinsert", "tremove", "getn".
+ new io functions "flush", "seek".
Lua is freely available for both academic and commercial purposes and
can be downloaded from the sites below. The current version is 3.2.

* Contacting the authors
Lua has been developed at TeCGraf, the Computer Graphics Technology Group
of PUC-Rio (the Pontifical Catholic University of Rio de Janeiro in Brazil).
TeCGraf is a laboratory of the Department of Computer Science.
Dozens of industrial products developed by TeCGraf use Lua.
