+Minetest-c55
+---------------
+An InfiniMiner/Minecraft inspired game.
+Copyright (c) 2010-2011 Perttu Ahola <celeron55@gmail.com>
+(see source files for other contributors)
+
+Further documentation:
+----------------------
+- Website: http://celeron.55.lt/~celeron55/minetest/
+- Wiki: http://celeron.55.lt/~celeron55/minetest/wiki/
+- Forum: http://celeron.55.lt/~celeron55/minetest/forum/
+- doc/ directory of source distribution
+
+This game is not finished:
+--------------------------
+- Don't expect it to work as well as a finished game will.
+- Please report any bugs to me. debug.txt is useful.
+
+Controls:
+---------
+- See the in-game pause menu
+- Settable in the configuration file, see the section below.
+
+Map directory:
+--------------
+- Map is stored in a directory, which can be removed to generate a new map.
+- There is a command-line option for it: --map-dir
+- For a RUN_IN_PLACE build, it is located in:
+		../map
+- Otherwise something like this:
+	Windows: C:\Documents and Settings\user\Application Data\minetest\map
+	Linux: ~/.minetest/map
+	OS X: ~/Library/Application Support/minetest/map
+
+Configuration file:
+-------------------
+- An optional configuration file can be used. See minetest.conf.example.
+- Path to file can be passed as a parameter to the executable:
+	--config <path-to-file>
+- Defaults:
+	- If built with -DRUN_IN_PLACE=1:
+		../minetest.conf
+		../../minetest.conf
+	- Otherwise something like this:
+		Windows: C:\Documents and Settings\user\Application Data\minetest\minetest.conf
+		Linux: ~/.minetest/minetest.conf
+		OS X: ~/Library/Application Support/minetest.conf
+
+Command-line options:
+---------------------
+- Use --help
+
+Compiling on GNU/Linux:
+-----------------------
+
+Install dependencies. Here's an example for Debian/Ubuntu:
+$ apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng12-dev libjpeg8-dev libxxf86vm-dev libgl1-mesa-dev
+
+Download source, extract (this is the URL to the latest of source repository, which might not work at all times):
+$ wget https://bitbucket.org/celeron55/minetest/get/tip.tar.gz
+$ tar xf tip.tar.gz
+$ cd minetest
+
+Build a version that runs directly from the source directory:
+$ cmake . -DRUN_IN_PLACE=1
+$ make -j2
+
+Run it:
+$ cd bin
+$ ./minetest
+
+- Use cmake . -LH to see all CMake options and their current state
+- If you want to install it system-wide (or are making a distribution package), you will want to use -DRUN_IN_PLACE=0
+- You can build a bare server or a bare client by specifying -DBUILD_CLIENT=0 or -DBUILD_SERVER=0
+- You can select between Release and Debug build by -DCMAKE_BUILD_TYPE=<Debug or Release>
+  - Note that the Debug build is considerably slower
+
+Compiling on Windows:
+---------------------
+
+- You need:
+	* CMake:
+		http://www.cmake.org/cmake/resources/software.html
+	* MinGW or Visual Studio
+		http://www.mingw.org/
+		http://msdn.microsoft.com/en-us/vstudio/default
+	* Irrlicht SDK 1.7:
+		http://irrlicht.sourceforge.net/downloads.html
+	* Zlib headers (zlib125.zip)
+		http://www.winimage.com/zLibDll/index.html
+	* Zlib library (zlibwapi.lib and zlibwapi.dll from zlib125dll.zip):
+		http://www.winimage.com/zLibDll/index.html
+	* And, of course, Minetest-c55:
+		http://celeron.55.lt/~celeron55/minetest/download
+- Steps:
+	- Select a directory called DIR hereafter in which you will operate.
+	- Make sure you have CMake and a compiler installed.
+	- Download all the other stuff to DIR and extract them into there. All those
+	  packages contain a nice base directory in them, which should end up being
+	  the direct subdirectories of DIR.
+	- You will end up with a directory structure like this (+=dir, -=file):
+	-----------------
+	+ DIR
+		- zlib-1.2.5.tar.gz
+		- zlib125dll.zip
+		- irrlicht-1.7.1.zip
+		- 110214175330.zip (or whatever, this is the minetest source)
+		+ zlib-1.2.5
+			- zlib.h
+			+ win32
+			...
+		+ zlib125dll
+			- readme.txt
+			+ dll32
+			...
+		+ irrlicht-1.7.1
+			+ lib
+			+ include
+			...
+		+ minetest
+			+ src
+			+ doc
+			- CMakeLists.txt
+			...
+	-----------------
+	- Start up the CMake GUI
+	- Select "Browse Source..." and select DIR/minetest
+	- Now, if using MSVC:
+		- Select "Browse Build..." and select DIR/minetest-build
+	- Else if using MinGW:
+		- Select "Browse Build..." and select DIR/minetest
+	- Select "Configure"
+	- Select your compiler
+	- It will warn about missing stuff, ignore that at this point. (later don't)
+	- Make sure the configuration is as follows
+	  (note that the versions may differ for you):
+	-----------------
+	BUILD_CLIENT             [X]
+	BUILD_SERVER             [ ]
+	CMAKE_BUILD_TYPE         Release
+	CMAKE_INSTALL_PREFIX     DIR/minetest-install
+	IRRLICHT_SOURCE_DIR      DIR/irrlicht-1.7.1
+	RUN_IN_PLACE             [X]
+	WARN_ALL                 [ ]
+	ZLIB_DLL                 DIR/zlib125dll/dll32/zlibwapi.dll
+	ZLIB_INCLUDE_DIR         DIR/zlib-1.2.5
+	ZLIB_LIBRARIES           DIR/zlib125dll/dll32/zlibwapi.lib
+	-----------------
+	- Hit "Configure"
+	- Hit "Generate"
+	If using MSVC:
+		- Open the generated minetest.sln
+		- The project defaults to the "Debug" configuration. Make very sure to
+		  select "Release", unless you want to debug some stuff (it's slower)
+		- Build the ALL_BUILD project
+		- Build the INSTALL project
+		- You should now have a working game with the executable in
+			DIR/minetest-install/bin/minetest.exe
+		- Additionally you may create a zip package by building the PACKAGE
+		  project.
+	If using MinGW:
+		- Using the command line, browse to the build directory and run 'make'
+		  (or mingw32-make or whatever it happens to be)
+		- You should now have a working game with the executable in
+			DIR/minetest/bin/minetest.exe

+I'll try to quickly document the newest block format in here (might contain
+errors). Refer to the mapgen or minetestmapper script for the directory
+structure and file naming. There are two sector namings possible,
+sector/XXXXZZZZ and sector/XXX/ZZZ.
+
+There also exists files map_meta.txt and chunk_meta, that are used by the
+generator. If they are not found or invalid, the generator will currently
+behave quite strangely.

+NOTE: Byte order is MSB first.
+
+u8 version
+- map format version number, this one is version 17
+
+u8 flags
+- Flag bitmasks:
+  - 0x01: is_underground: Should be set to 0 if there will be no light
+    obstructions above the block. If/when sunlight of a block is updated and
+	there is no block above it, this value is checked for determining whether
+	sunlight comes from the top.
+  - 0x02: day_night_differs: Whether the lighting of the block is different on
+    day and night. Only blocks that have this bit set are updated when day
+	transforms to night.
+  - 0x04: lighting_expired: If true, lighting is invalid and should be updated.
+    If you can't calculate lighting in your generator properly, you could try
+	setting this 1 to everything and setting the uppermost block in every
+	sector as is_underground=0. I am quite sure it doesn't work properly,
+	though.

+Minetest-c55 protocol (incomplete, early draft):
+Updated 2011-06-18
+
+A custom protocol over UDP.
+Integers are big endian.
+Refer to connection.{h,cpp} for further reference.
+
+Initialization:
+- A dummy reliable packet with peer_id=PEER_ID_INEXISTENT=0 is sent to the server:
+	- Actually this can be sent without the reliable packet header, too, i guess,
+	  but the sequence number in the header allows the sender to re-send the
+	  packet without accidentally getting a double initialization.
+	- Packet content:
+		# Basic header
+		u32 protocol_id = PROTOCOL_ID = 0x4f457403
+		u16 sender_peer_id = PEER_ID_INEXISTENT = 0
+		u8 channel = 0
+		# Reliable packet header
+		u8 type = TYPE_RELIABLE = 3
+		u16 seqnum = SEQNUM_INITIAL = 65500
+		# Original packet header
+		u8 type = TYPE_ORIGINAL = 1
+		# And no actual payload.
+- Server responds with something like this:
+	- Packet content:
+		# Basic header
+		u32 protocol_id = PROTOCOL_ID = 0x4f457403
+		u16 sender_peer_id = PEER_ID_INEXISTENT = 0
+		u8 channel = 0
+		# Reliable packet header
+		u8 type = TYPE_RELIABLE = 3
+		u16 seqnum = SEQNUM_INITIAL = 65500
+		# Control packet header
+		u8 type = TYPE_CONTROL = 0
+		u8 controltype = CONTROLTYPE_SET_PEER_ID = 1
+		u16 peer_id_new = assigned peer id to client (other than 0 or 1)
+- Then the connection can be disconnected by sending:
+	- Packet content:
+		# Basic header
+		u32 protocol_id = PROTOCOL_ID = 0x4f457403
+		u16 sender_peer_id = whatever was gotten in CONTROLTYPE_SET_PEER_ID
+		u8 channel = 0
+		# Control packet header
+		u8 type = TYPE_CONTROL = 0
+		u8 controltype = CONTROLTYPE_DISCO = 2
+
+- Here's a quick untested connect-disconnect done in PHP:

+	- Think about using same bits for material for fences and doors, for
+	example
+- Finish the ActiveBlockModifier stuff and use it for something
+- Move mineral to param2, increment map serialization version, add conversion
+
+TODO: Add a per-sector database to store surface stuff as simple flags/values
+      - Light?
+	  - A building?
+	  And at some point make the server send this data to the client too,
+	  instead of referring to the noise functions
+	  - Ground height
+	  - Surface ground type
+	  - Trees?
+
+TODO: Restart irrlicht completely when coming back to main menu from game.
+	- This gets rid of everything that is stored in irrlicht's caches.
+
+TODO: Merge bahamada's audio stuff (clean patch available)
+
+TODO: Merge spongie's chest/furnace direction (by hand)
+
+TODO: Merge key configuration menu (no clean patch available)
 
 Making it more portable:
 ------------------------
  
 Stuff to do before release:
 ---------------------------
-- Player default privileges and default password
-- Chat privilege
-- Some simple block-based dynamic stuff in the world (finish the
-  ActiveBlockModifier stuff)
-- Protocol version field
-- Consider getting some textures from cisoun's texture pack
-- Add a long step function to objects that is called with the time
-  difference when block activates
+
+Fixes to the current release:
+-----------------------------
+
+Stuff to do after release:
+---------------------------
+
+Doing currently:
+----------------
+
+TODO: Use MapBlock::resetUsageTimer() in appropriate places
+      (on client and server)
