-<H2><A NAME="about">About Lua</A></H2>
-<P>
-Lua is a powerful, fast, lightweight, embeddable scripting language
-developed by a
-<A HREF="http://www.lua.org/authors.html">team</A>
-at
-<A HREF="http://www.puc-rio.br/">PUC-Rio</A>,
-the Pontifical Catholic University of Rio de Janeiro in Brazil.
-Lua is
-<A HREF="#license">free software</A>
-used in many products and projects around the world.
-
-<P>
-Lua's
-<A HREF="http://www.lua.org/">official web site</A>
-provides complete information
-about Lua,
-including
-an
-<A HREF="http://www.lua.org/about.html">executive summary</A>
-and
-updated
-<A HREF="http://www.lua.org/docs.html">documentation</A>,
-especially the
-<A HREF="http://www.lua.org/manual/5.3/">reference manual</A>,
-which may differ slightly from the
-<A HREF="contents.html">local copy</A>
-distributed in this package.
-
-<H2><A NAME="install">Installing Lua</A></H2>
-<P>
-Lua is distributed in
-<A HREF="http://www.lua.org/ftp/">source</A>
-form.
-You need to build it before using it.
-Building Lua should be straightforward
-because
-Lua is implemented in pure ANSI C and compiles unmodified in all known
-platforms that have an ANSI C compiler.
-Lua also compiles unmodified as C++.
-The instructions given below for building Lua are for Unix-like platforms.
-See also
-<A HREF="#other">instructions for other systems</A>
-and
-<A HREF="#customization">customization options</A>.
-
-<P>
-If you don't have the time or the inclination to compile Lua yourself,
-get a binary from
-<A HREF="http://lua-users.org/wiki/LuaBinaries">LuaBinaries</A>.
-Try also
-<A HREF="http://luadist.org/">LuaDist</A>,
-a multi-platform distribution of Lua that includes batteries.
-
-<H3>Building Lua</H3>
-<P>
-In most Unix-like platforms, simply do "<KBD>make</KBD>" with a suitable target.
-Here are the details.
-
-<OL>
-<LI>
-Open a terminal window and move to
-the top-level directory, which is named <TT>lua-5.3.x</TT>.
-The <TT>Makefile</TT> there controls both the build process and the installation process.
-<P>
-<LI>
- Do "<KBD>make</KBD>" and see if your platform is listed.
- The platforms currently supported are:
-<P>
-<P CLASS="display">
- aix bsd c89 freebsd generic linux macosx mingw posix solaris
-</P>
-<P>
- If your platform is listed, just do "<KBD>make xxx</KBD>", where xxx
- is your platform name.
-<P>
- If your platform is not listed, try the closest one or posix, generic,
- c89, in this order.
-<P>
-<LI>
-The compilation takes only a few moments
-and produces three files in the <TT>src</TT> directory:
-lua (the interpreter),
-luac (the compiler),
-and liblua.a (the library).
-<P>
-<LI>
- To check that Lua has been built correctly, do "<KBD>make test</KBD>"
- after building Lua. This will run the interpreter and print its version.
-</OL>
-<P>
-If you're running Linux and get compilation errors,
-make sure you have installed the <TT>readline</TT> development package
-(which is probably named <TT>libreadline-dev</TT> or <TT>readline-devel</TT>).
-If you get link errors after that,
-then try "<KBD>make linux MYLIBS=-ltermcap</KBD>".
-
-<H3>Installing Lua</H3>
-<P>
- Once you have built Lua, you may want to install it in an official
- place in your system. In this case, do "<KBD>make install</KBD>". The official
- place and the way to install files are defined in the <TT>Makefile</TT>. You'll
- probably need the right permissions to install files.
-
-<P>
- To build and install Lua in one step, do "<KBD>make xxx install</KBD>",
- where xxx is your platform name.
-
-<P>
- To install Lua locally, do "<KBD>make local</KBD>".
- This will create a directory <TT>install</TT> with subdirectories
- <TT>bin</TT>, <TT>include</TT>, <TT>lib</TT>, <TT>man</TT>, <TT>share</TT>,
- and install Lua as listed below.
-
- To install Lua locally, but in some other directory, do
- "<KBD>make install INSTALL_TOP=xxx</KBD>", where xxx is your chosen directory.
- The installation starts in the <TT>src</TT> and <TT>doc</TT> directories,
- so take care if <TT>INSTALL_TOP</TT> is not an absolute path.
-
-<DL CLASS="display">
-<DT>
- bin:
-<DD>
- lua luac
-<DT>
- include:
-<DD>
- lua.h luaconf.h lualib.h lauxlib.h lua.hpp
-<DT>
- lib:
-<DD>
- liblua.a
-<DT>
- man/man1:
-<DD>
- lua.1 luac.1
-</DL>
-
-<P>
- These are the only directories you need for development.
- If you only want to run Lua programs,
- you only need the files in <TT>bin</TT> and <TT>man</TT>.
- The files in <TT>include</TT> and <TT>lib</TT> are needed for
- embedding Lua in C or C++ programs.
-
-<H3><A NAME="customization">Customization</A></H3>
-<P>
- Three kinds of things can be customized by editing a file:
-<UL>
- <LI> Where and how to install Lua &mdash; edit <TT>Makefile</TT>.
- <LI> How to build Lua &mdash; edit <TT>src/Makefile</TT>.
- <LI> Lua features &mdash; edit <TT>src/luaconf.h</TT>.
-</UL>
-
-<P>
- You don't actually need to edit the Makefiles because you may set the
- relevant variables in the command line when invoking make.
- Nevertheless, it's probably best to edit and save the Makefiles to
- record the changes you've made.
-
-<P>
- On the other hand, if you need to customize some Lua features, you'll need
- to edit <TT>src/luaconf.h</TT> before building and installing Lua.
- The edited file will be the one installed, and
- it will be used by any Lua clients that you build, to ensure consistency.
- Further customization is available to experts by editing the Lua sources.
-
-<H3><A NAME="other">Building Lua on other systems</A></H3>
-<P>
- If you're not using the usual Unix tools, then the instructions for
- building Lua depend on the compiler you use. You'll need to create
- projects (or whatever your compiler uses) for building the library,
- the interpreter, and the compiler, as follows:
-
-<DL CLASS="display">
-<DT>
-library:
-<DD>
-lapi.c lcode.c lctype.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c
-lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c ltable.c
-ltm.c lundump.c lvm.c lzio.c
-lauxlib.c lbaselib.c lbitlib.c lcorolib.c ldblib.c liolib.c
-lmathlib.c loslib.c lstrlib.c ltablib.c lutf8lib.c loadlib.c linit.c
-<DT>
-interpreter:
-<DD>
- library, lua.c
-<DT>
-compiler:
-<DD>
- library, luac.c
-</DL>
-
-<P>
- To use Lua as a library in your own programs you'll need to know how to
- create and use libraries with your compiler. Moreover, to dynamically load
- C libraries for Lua you'll need to know how to create dynamic libraries
- and you'll need to make sure that the Lua API functions are accessible to
- those dynamic libraries &mdash; but <EM>don't</EM> link the Lua library
- into each dynamic library. For Unix, we recommend that the Lua library
- be linked statically into the host program and its symbols exported for
- dynamic linking; <TT>src/Makefile</TT> does this for the Lua interpreter.
- For Windows, we recommend that the Lua library be a DLL.
- In all cases, the compiler luac should be linked statically.
-
-<P>
- As mentioned above, you may edit <TT>src/luaconf.h</TT> to customize
- some features before building Lua.
-
