+
+
+=== INTRODUCTION ===
+
+Lua-iconv is a Lua binding to the POSIX 'iconv' library. The iconv
+library converts a sequence of characters from one codeset into a
+sequence of corresponding characters in another codeset. The codesets
+are those specified in the iconv.new() call that returned the conversion
+descriptor, cd.
+
+Details regarding iconv may be obtained from:
+http://www.opengroup.org/onlinepubs/007908799/xsh/iconv.h.html
+

+
+
+
+=== DOWNLOAD AND INSTALLATION ===
+
+Lua-iconv can be obtained from its Luaforge project page:
+http://lua-iconv.luaforge.net/
+
+Lua-iconv must be compiled as a shared object and loaded by the Lua
+interpreter using the 'loadlib' facility (or the new module system in
+Lua 5.1). To compile the library, just fire up your favourite shell, untar
+the distribution package and type, as root, within the program directory:
+
+    make install
+
+The library will be compiled and installed on the /usr/lib/ directory.
+
+To install the library with Lua 5.1 and above just type
+
+    make install51
+
+This will cause the Makefile to run a Lua script that will install the
+library into a directory from package.cpath, allowing you to use the
+package system to load the library.
+
+
+
+=== LOADING AND INITIALIZATION ===
+
+Lua-iconv is a shared library that exports a single function called
+luaopen_iconv that must be called by the Lua interpreter. You must
+use loadlib function to for that. Using Lua 5.0, under Unix and with
+libluaiconv.so on your LUA_PATH (or also your LD_PATH) you can just do:
+
+    assert(loadlib("libluaiconv.so", "luaopen_iconv"))()
+
+And, under Windows and with libluaiconv.dll on your path, you can do
+
+    assert(loadlib("libluaiconv.dll", "luaopen_iconv"))()
+
+On the Lua 5.1, Lua-iconv uses the new package system that allows you
+to simply do a
+
+    require "gd"
+
+call to load up the library (that was installed on the right place by
+install51.lua).
+
+
+
+=== USAGE ===
+
+cd = iconv.new(to, from)
+cd = iconv.open(to, from)
+
+    Opens a new conversion descriptor, from the 'from' charset to the
+    'to' charset. Concatenating "//TRANSLIT" to the first argument will
+    enable character transliteration and concatenating "//IGNORE" to
+    the first argument will cause iconv to ignore any invalid characters
+    found in the input string.
+
+    This function returns a new converter or nil on error.
+
+
+nstr, err = cd:iconv(str)
+
+    Converts the 'str' string to the desired charset. This method always
+    returns two arguments: the converted string and an error code, which
+    may have any of the following values:
+
+    nil
+        No error. Conversion was succeful.
+
+    iconv.ERROR_NO_MEMORY
+        Failed to allocate enough memory in the conversion process.
+
+    iconv.ERROR_INVALID
+        An invalid character was found in the input sequence.
+
+    iconv.ERROR_INCOMPLETE
+        An incomplete character was found in the input sequence.
+        
+    iconv.ERROR_UNKNOWN
+        There was an unknown error.

-# Lua-iconv
-
-Perform character set conversions in Lua
-
-(c) 2005-11 Alexandre Erwin Ittner <alexandre@ittner.com.br>
-
-
-## Introduction
-
-Lua-iconv provides POSIX 'iconv' bindings for the Lua Programming Language.
-The iconv library converts a sequence of characters from one codeset into a sequence of corresponding characters in another codeset.
-The codesets are those specified in the `iconv.new()` call that returned the conversion descriptor, `cd`.
-
-Lua-iconv 7 *requires* Lua 5.1 or Lua 5.2. For Lua 5.0, use the first release (lua-iconv-r1).
-
-Details on iconv may be obtained in the [Open Group's interface definition](http://www.opengroup.org/onlinepubs/007908799/xsh/iconv.h.html).
-
-
-## Download and installation
-
-Lua-iconv can be obtained from [its GitHub project page](https://github.com/lunarmodules/lua-iconv), from a LuaRocks server, or from some Linux distributions which already provide it (eg. Debian).
-
-Unless you downloaded a compiled package, you must build the library for your system.
-If you have LuaRocks installed, all the process is automatic; just fire up your favourite shell and type, as root:
-
-```console
-luarocks install lua-iconv
-```
-
-and the package will be downloaded from a rock server, installed and configured.
-Otherwise, you must compile and install the package.
-In a system with pkg-config (as many Linux distributions and Unix flavors) open a shell, untar the distribution package and, within the program directory, type:
-
-```console
-make install
-```
-
-as root.
-The library will be compiled and installed on the in the correct path (which is defined in lua5.x.pc).
-Compiling on systems without pkg-config requires manual changes in the Makefile (this includes Windows).
-
-
-## Loading and initialization
-
-Lua-iconv is a shared library that must be loaded in the Lua interpreter before use.
-You can simply do a
-
-```lua
-local iconv = require("iconv")
-```
-
-call to load up the library (that, of course, must be installed in a directory from `package.cpath`).
-
-
-## API documentation
-
-```lua
-cd, err = iconv.new(to, from)
-cd, err = iconv.open(to, from)
-```
-
-Opens a new conversion descriptor, from the 'from' charset to the 'to' charset.
-Concatenating "//TRANSLIT" to the first argument will enable character transliteration and concatenating "//IGNORE" to the first argument will cause iconv to ignore any invalid characters found in the input string.
-
-The error code, may have any of the following values:
-
-* `nil`
-
-    No error. Creation was successful.
-
-* `iconv.ERROR_INVALID`
-
-    The conversion from `from` to `to` is not supported by the implementation.
-
-* `iconv.ERROR_UNKNOWN`
-
-    There was an unknown error.
-
-
-This function returns a new converter or nil+err on error.
-
-
-```lua
-nstr, err = cd:iconv(str)
-```
-
-Converts the 'str' string to the desired charset.
-This method always returns two arguments: the converted string and an error code, which may have any of the following values:
-
-* `nil`
-
-    No error. Conversion was successful.
-
-* `iconv.ERROR_NO_MEMORY`
-
-    Failed to allocate enough memory in the conversion process.
-
-* `iconv.ERROR_INVALID`
-
-    An invalid character was found in the input sequence.
-
-* `iconv.ERROR_INCOMPLETE`
-
-    An incomplete character was found in the input sequence.
-
-* `iconv.ERROR_FINALIZED`
-
-    Trying to use an already-finalized converter. This usually means
-    that the user was tweaking the garbage collector private methods.
-
-* `iconv.ERROR_UNKNOWN`
-
-    There was an unknown error.
