-HISTORY for Lua 5.1
-
-* Changes from version 5.0 to 5.1
-  -------------------------------
-  Language:
-  + new module system.
-  + new semantics for control variables of fors.
-  + new semantics for setn/getn.
-  + new syntax/semantics for varargs.
-  + new long strings and comments.
-  + new `mod' operator (`%')
-  + new length operator #t
-  + metatables for all types
-  API:
-  + new functions: lua_createtable, lua_get(set)field, lua_push(to)integer.
-  + user supplies memory allocator (lua_open becomes lua_newstate).
-  + luaopen_* functions must be called through Lua.
-  Implementation:
-  + new configuration scheme via luaconf.h.
-  + incremental garbage collection.
-  + better handling of end-of-line in the lexer.
-  + fully reentrant parser (new Lua function `load')
-  + better support for 64-bit machines.
-  + native loadlib support for Mac OS X.
-  + standard distribution in only one library (lualib.a merged into lua.a)
-
-* Changes from version 4.0 to 5.0
-  -------------------------------
-  Language:
-  + lexical scoping.
-  + Lua coroutines.
-  + standard libraries now packaged in tables.
-  + tags replaced by metatables and tag methods replaced by metamethods,
-    stored in metatables.
-  + proper tail calls.
-  + each function can have its own global table, which can be shared.
-  + new __newindex metamethod, called when we insert a new key into a table.
-  + new block comments: --[[ ... ]].
-  + new generic for.
-  + new weak tables.
-  + new boolean type.
-  + new syntax "local function".
-  + (f()) returns the first value returned by f.
-  + {f()} fills a table with all values returned by f.
-  + \n ignored in [[\n .
-  + fixed and-or priorities.
-  + more general syntax for function definition (e.g. function a.x.y:f()...end).
-  + more general syntax for function calls (e.g. (print or write)(9)).
-  + new functions (time/date, tmpfile, unpack, require, load*, etc.).
-  API:
-  + chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer.
-  + introduced lightweight userdata, a simple "void*" without a metatable.
-  + new error handling protocol: the core no longer prints error messages;
-    all errors are reported to the caller on the stack.
-  + new lua_atpanic for host cleanup.
-  + new, signal-safe, hook scheme.
-  Implementation:
-  + new license: MIT.
-  + new, faster, register-based virtual machine.
-  + support for external multithreading and coroutines.
-  + new and consistent error message format.
-  + the core no longer needs "stdio.h" for anything (except for a single
-    use of sprintf to convert numbers to strings).
-  + lua.c now runs the environment variable LUA_INIT, if present. It can
-    be "@filename", to run a file, or the chunk itself.
-  + support for user extensions in lua.c.
-    sample implementation given for command line editing.
-  + new dynamic loading library, active by default on several platforms.
-  + safe garbage-collector metamethods.
-  + precompiled bytecodes checked for integrity (secure binary dostring).
-  + strings are fully aligned.
-  + position capture in string.find.
-  + read('*l') can read lines with embedded zeros.
-
-* Changes from version 3.2 to 4.0
-  -------------------------------
-  Language:
-  + new "break" and "for" statements (both numerical and for tables).
-  + uniform treatment of globals: globals are now stored in a Lua table.
-  + improved error messages.
-  + no more '$debug': full speed *and* full debug information.
-  + new read form: read(N) for next N bytes.
-  + general read patterns now deprecated.
-    (still available with -DCOMPAT_READPATTERNS.)
-  + all return values are passed as arguments for the last function
-    (old semantics still available with -DLUA_COMPAT_ARGRET)
-  + garbage collection tag methods for tables now deprecated.
-  + there is now only one tag method for order.
-  API:
-  + New API: fully re-entrant, simpler, and more efficient.
-  + New debug API.
-  Implementation:
-  + faster than ever: cleaner virtual machine and new hashing algorithm.
-  + non-recursive garbage-collector algorithm.
-  + reduced memory usage for programs with many strings.
-  + improved treatment for memory allocation errors.
-  + improved support for 16-bit machines (we hope).
-  + code now compiles unmodified as both ANSI C and C++.
-  + numbers in bases other than 10 are converted using strtoul.
-  + new -f option in Lua to support #! scripts.
-  + luac can now combine text and binaries.
-
-* Changes from version 3.1 to 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".
-
-* Changes from version 3.0 to 3.1
-  -------------------------------
-  + NEW FEATURE: anonymous functions with closures (via "upvalues").
-  + new syntax:
-    - local variables in chunks.
-    - better scope control with DO block END.
-    - constructors can now be also written: { record-part; list-part }.
-    - more general syntax for function calls and lvalues, e.g.:
-      f(x).y=1
-      o:f(x,y):g(z)
-      f"string" is sugar for f("string")
-  + strings may now contain arbitrary binary data (e.g., embedded zeros).
-  + major code re-organization and clean-up; reduced module interdependecies.
-  + no arbitrary limits on the total number of constants and globals.
-  + support for multiple global contexts.
-  + better syntax error messages.
-  + new traversal functions "foreach" and "foreachvar".
-  + the default for numbers is now double.
-    changing it to use floats or longs is easy.
-  + complete debug information stored in pre-compiled chunks.
-  + sample interpreter now prompts user when run interactively, and also
-    handles control-C interruptions gracefully.
-
-* Changes from version 2.5 to 3.0
-  -------------------------------
-  + NEW CONCEPT: "tag methods".
-    Tag methods replace fallbacks as the meta-mechanism for extending the
-    semantics of Lua. Whereas fallbacks had a global nature, tag methods
-    work on objects having the same tag (e.g., groups of tables).
-    Existing code that uses fallbacks should work without change.
-  + new, general syntax for constructors {[exp] = exp, ... }.
-  + support for handling variable number of arguments in functions (varargs).
-  + support for conditional compilation ($if ... $else ... $end).
-  + cleaner semantics in API simplifies host code.
-  + better support for writing libraries (auxlib.h).
-  + better type checking and error messages in the standard library.
-  + luac can now also undump.
-
-* Changes from version 2.4 to 2.5
-  -------------------------------
-  + io and string libraries are now based on pattern matching;
-    the old libraries are still available for compatibility
-  + dofile and dostring can now return values (via return statement)
-  + better support for 16- and 64-bit machines
-  + expanded documentation, with more examples
-
-* Changes from version 2.2 to 2.4
-  -------------------------------
-  + 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
-  + expanded documentation, with more examples
-
-* Changes from version 2.1 to 2.2
-  -------------------------------
-  + functions now may be declared with any "lvalue" as a name
-  + garbage collection of functions
-  + support for pipes
-
-* Changes from version 1.1 to 2.1
-  -------------------------------
-  + object-oriented support
-  + fallbacks
-  + simplified syntax for tables
-  + many internal improvements

-INSTALL for Lua 5.1
-
-* Building Lua
-  ------------
-  Lua is built in the src directory, but the build process can be
-  controlled from the top-level Makefile.
-
-  Building Lua on Unix systems should be very easy. First do "make" and
-  see if your platform is listed. If so, just do "make xxx", where xxx
-  is your platform name. The platforms currently supported are:
-    aix ansi bsd freebsd generic linux macosx mingw posix solaris
-
-  If your platform is not listed, try the closest one or posix, generic,
-  ansi, in this order.
-
-  See below for customization instructions and for instructions on how
-  to build with other Windows compilers.
-
-  If you want to check that Lua has been built correctly, do "make test"
-  after building Lua. Also, have a look at the example programs in test.
-
-* Installing Lua
-  --------------
-  Once you have built Lua, you may want to install it in an official
-  place in your system. In this case, do "make install". The official
-  place and the way to install files are defined in Makefile. You must
-  have the right permissions to install files.
-
-  If you want to build and install Lua in one step, do "make xxx install",
-  where xxx is your platform name.
-
-  If you want to install Lua locally, then do "make local". This will
-  create directories bin, include, lib, man, and install Lua there as
-  follows:
-
-    bin:	lua luac
-    include:	lua.h luaconf.h lualib.h lauxlib.h lua.hpp
-    lib:	liblua.a
-    man/man1:	lua.1 luac.1
-
-  These are the only directories you need for development.
-
-  There are man pages for lua and luac, in both nroff and html, and a
-  reference manual in html in doc, some sample code in test, and some
-  useful stuff in etc. You don't need these directories for development.
-
-  If you want to install Lua locally, but in some other directory, do
-  "make install INSTALL_TOP=xxx", where xxx is your chosen directory.
-
-  See below for instructions for Windows and other systems.
-
-* Customization
-  -------------
-  Three things can be customized by editing a file:
-    - Where and how to install Lua -- edit Makefile.
-    - How to build Lua -- edit src/Makefile.
-    - Lua features -- edit src/luaconf.h.
-
-  You don't actually need to edit the Makefiles because you may set the
-  relevant variables when invoking make.
-
-  On the other hand, if you need to select some Lua features, you'll need
-  to edit src/luaconf.h. The edited file will be the one installed, and
-  it will be used by any Lua clients that you build, to ensure consistency.
-
-  We strongly recommend that you enable dynamic loading. This is done
-  automatically for all platforms listed above that have this feature
-  (and also Windows). See src/luaconf.h and also src/Makefile.
-
-* Building Lua on Windows and other systems
-  -----------------------------------------
-  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:
-
-  library:	lapi.c lcode.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 ldblib.c liolib.c lmathlib.c loslib.c
-		ltablib.c lstrlib.c loadlib.c linit.c
-
-  interpreter:	library, lua.c
-
-  compiler:	library, luac.c print.c
-
-  If you use Visual Studio .NET, you can use etc/luavs.bat in its
-  "Command Prompt".
-
-  If all you want is to build the Lua interpreter, you may put all .c files
-  in a single project, except for luac.c and print.c. Or just use etc/all.c.
-
-  To use Lua as a library in your own programs, you'll need to know how to
-  create and use libraries with your compiler.
-
-  As mentioned above, you may edit luaconf.h to select some features before
-  building Lua.

-lua \- Lua interpreter
-.SH SYNOPSIS
-.B lua
-[

-]
-[

-[

-]
-]
-.SH DESCRIPTION
-.B lua
-is the stand-alone Lua interpreter.
-It loads and executes Lua programs,
-either in textual source form or
-in precompiled binary form.
-(Precompiled binaries are output by
-.BR luac ,
-the Lua compiler.)
-.B lua
-can be used as a batch interpreter and also interactively.
-.LP
-The given
-.I options
-(see below)
-are executed and then
-the Lua program in file
-.I script
-is loaded and executed.
-The given
-.I args
-are available to
-.I script
-as strings in a global table named
-.BR arg .
-If these arguments contain spaces or other characters special to the shell,
-then they should be quoted
-(but note that the quotes will be removed by the shell).
-The arguments in
-.B arg
-start at 0,
-which contains the string
-.RI ' script '.
-The index of the last argument is stored in
-.BR arg.n .
-The arguments given in the command line before
-.IR script ,
-including the name of the interpreter,
-are available in negative indices in
-.BR arg .
-.LP
-At the very start,
-before even handling the command line,
-.B lua
-executes the contents of the environment variable
-.BR LUA_INIT ,
-if it is defined.
-If the value of
-.B LUA_INIT
-is of the form
-.RI '@ filename ',
-then
-.I filename
-is executed.
-Otherwise, the string is assumed to be a Lua statement and is executed.
-.LP
-Options start with
-.B '\-'
-and are described below.
-You can use
-.B "'\--'"
-to signal the end of options.
-.LP
-If no arguments are given,
-then
-.B "\-v \-i"
-is assumed when the standard input is a terminal;
-otherwise,
-.B "\-"
-is assumed.
-.LP
-In interactive mode,
-.B lua
-prompts the user,
-reads lines from the standard input,
-and executes them as they are read.
-If a line does not contain a complete statement,
-then a secondary prompt is displayed and
-lines are read until a complete statement is formed or
-a syntax error is found.
-So, one way to interrupt the reading of an incomplete statement is
-to force a syntax error:
-adding a
-.B ';' 
-in the middle of a statement is a sure way of forcing a syntax error
-(except inside multiline strings and comments; these must be closed explicitly).
-If a line starts with
-.BR '=' ,
-then
-.B lua
-displays the values of all the expressions in the remainder of the
-line. The expressions must be separated by commas.
-The primary prompt is the value of the global variable
-.BR _PROMPT ,
-if this value is a string;
-otherwise, the default prompt is used.
-Similarly, the secondary prompt is the value of the global variable
-.BR _PROMPT2 .
-So,
-to change the prompts,
-set the corresponding variable to a string of your choice.
-You can do that after calling the interpreter
-or on the command line
-(but in this case you have to be careful with quotes
-if the prompt string contains a space; otherwise you may confuse the shell.)
-The default prompts are "> " and ">> ".
-.SH OPTIONS

-.SH NAME
-luac \- Lua compiler
-.SH SYNOPSIS
-.B luac
-[
-.I options
-] [
-.I filenames
-]
-.SH DESCRIPTION
-.B luac
-is the Lua compiler.
-It translates programs written in the Lua programming language
-into binary files that can be later loaded and executed.
-.LP
-The main advantages of precompiling chunks are:
-faster loading,
-protecting source code from accidental user changes,
-and
-off-line syntax checking.
-.LP
-Pre-compiling does not imply faster execution
-because in Lua chunks are always compiled into bytecodes before being executed.
-.B luac
-simply allows those bytecodes to be saved in a file for later execution.
-.LP
-Pre-compiled chunks are not necessarily smaller than the corresponding source.
-The main goal in pre-compiling is faster loading.
-.LP
-The binary files created by
-.B luac
-are portable only among architectures with the same word size and byte order.
-.LP
-.B luac
-produces a single output file containing the bytecodes
-for all source files given.
-By default,
-the output file is named
-.BR luac.out ,
-but you can change this with the
-.B \-o
-option.
-.LP
-In the command line,
-you can mix
-text files containing Lua source and
-binary files containing precompiled chunks.
-This is useful to combine several precompiled chunks,
-even from different (but compatible) platforms,
-into a single precompiled chunk.
-.LP
-You can use
-.B "'\-'"
-to indicate the standard input as a source file
-and
-.B "'\--'"
-to signal the end of options
-(that is,
-all remaining arguments will be treated as files even if they start with
-.BR "'\-'" ).
-.LP
-The internal format of the binary files produced by
-.B luac
-is likely to change when a new version of Lua is released.
-So,
-save the source files of all Lua programs that you precompile.
-.LP
-.SH OPTIONS
-Options must be separate.
-.TP
-.B \-l
-produce a listing of the compiled bytecode for Lua's virtual machine.
-Listing bytecodes is useful to learn about Lua's virtual machine.
-If no files are given, then
-.B luac
-loads
-.B luac.out
-and lists its contents.
-.TP
-.BI \-o " file"
-output to
-.IR file ,
-instead of the default
-.BR luac.out .
-(You can use
-.B "'\-'"
-for standard output,
-but not on platforms that open standard output in text mode.)
-The output file may be a source file because
-all files are loaded before the output file is written.
-Be careful not to overwrite precious files.
-.TP
-.B \-p
-load files but do not generate any output file.
-Used mainly for syntax checking and for testing precompiled chunks:
-corrupted files will probably generate errors when loaded.
-Lua always performs a thorough integrity test on precompiled chunks.
-Bytecode that passes this test is completely safe,
-in the sense that it will not break the interpreter.

-luac - Lua compiler
-<H2>SYNOPSIS</H2>
-<B>luac</B>
-[
-<I>options</I>
-] [
-<I>filenames</I>
-]
-<H2>DESCRIPTION</H2>
-<B>luac</B>
-is the Lua compiler.
-It translates programs written in the Lua programming language
-into binary files that can be later loaded and executed.
-<P>
-The main advantages of precompiling chunks are:
-faster loading,
-protecting source code from accidental user changes,
-and
-off-line syntax checking.
-<P>
-Precompiling does not imply faster execution
-because in Lua chunks are always compiled into bytecodes before being executed.
-<B>luac</B>
-simply allows those bytecodes to be saved in a file for later execution.
-<P>
-Precompiled chunks are not necessarily smaller than the corresponding source.
-The main goal in precompiling is faster loading.
-<P>
-The binary files created by
-<B>luac</B>
-are portable only among architectures with the same word size and byte order.
-<P>
-<B>luac</B>
-produces a single output file containing the bytecodes
-for all source files given.
-By default,
-the output file is named
-<B>luac.out</B>,
-but you can change this with the
-<B>-o</B>
-option.
-<P>
-In the command line,
-you can mix
-text files containing Lua source and
-binary files containing precompiled chunks.
-This is useful because several precompiled chunks,
-even from different (but compatible) platforms,
-can be combined into a single precompiled chunk.
-<P>
-You can use
-<B>'-'</B>
-to indicate the standard input as a source file
-and
-<B>'--'</B>
-to signal the end of options
-(that is,
-all remaining arguments will be treated as files even if they start with
-<B>'-'</B>).
-<P>
-The internal format of the binary files produced by
-<B>luac</B>
-is likely to change when a new version of Lua is released.
-So,
-save the source files of all Lua programs that you precompile.
-<P>
-<H2>OPTIONS</H2>
-Options must be separate.
-<P>
-<B>-l</B>
-produce a listing of the compiled bytecode for Lua's virtual machine.
-Listing bytecodes is useful to learn about Lua's virtual machine.
-If no files are given, then
-<B>luac</B>
-loads
-<B>luac.out</B>
-and lists its contents.
-<P>
-<B>-o </B><I>file</I>
-output to
-<I>file</I>,
-instead of the default
-<B>luac.out</B>.
-(You can use
-<B>'-'</B>
-for standard output,
-but not on platforms that open standard output in text mode.)
-The output file may be a source file because
-all files are loaded before the output file is written.
-Be careful not to overwrite precious files.
-<P>
-<B>-p</B>
-load files but do not generate any output file.
-Used mainly for syntax checking and for testing precompiled chunks:
-corrupted files will probably generate errors when loaded.
-Lua always performs a thorough integrity test on precompiled chunks.
-Bytecode that passes this test is completely safe,
-in the sense that it will not break the interpreter.
-However,
-there is no guarantee that such code does anything sensible.
-(None can be given, because the halting problem is unsolvable.)
-If no files are given, then
-<B>luac</B>
-loads
-<B>luac.out</B>
-and tests its contents.
-No messages are displayed if the file passes the integrity test.
-<P>
-<B>-s</B>
-strip debug information before writing the output file.
-This saves some space in very large chunks,
-but if errors occur when running a stripped chunk,
-then the error messages may not contain the full information they usually do.
-For instance,
-line numbers and names of local variables are lost.
