* What is Lua?
    Lua is a simple, yet powerful, language for extending applications.
    Lua has been developed by TeCGraf, the Computer Graphics Technology Group
    of PUC-Rio, the Pontifical Catholic University of Rio de Janeiro, Brazil.
    Dozens of industrial products developed by TeCGraf use Lua.

* Some features of Lua
    + a simple, pascal-like, syntax
    + powerful data description constructs (e.g., associative arrays)
    + user-controlled type constructors
    + fallbacks for extending the language in unconventional ways (e.g.,
        inheritance, overloading)
    + garbage collection
    + Lua programs are compiled into bytecodes, which are then interpreted
    + portable, written in ANSI C (runs in Unix, DOS, Windows, Mac, Cray, ...)

* Availability
    The latest version of Lua is always available at the following locations:
    In Brazil: ftp://ftp.icad.puc-rio.br/pub/lua/lua.tar.gz
    In Canada: ftp://csg.uwaterloo.ca/pub/lhf/lua/lua.tar.gz
    Home page: http://www.inf.puc-rio.br/~roberto/lua.html
    The current version is 2.4.

* Changes since version 2.2 (version 2.3 was never publicly released)
    + external compiler creates portable binary files that can be loaded faster
    + interface for debugging and profiling
    + new "getglobal" fallback
    + new functions for handling references to Lua objects
    + new functions in standard lib
    + only one copy of each string is stored
    + better documentation

* Legal matters
    Lua is freely available for both academic and commercial purposes.
    Lua is not in the public domain; TeCGraf keeps its copyright.

* Contacting the authors
    Send your comments, bug reports and anything else to lua@icad.puc-rio.br.
    Please send us email if you download Lua so that we can know how far it goes.
