+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other

+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General

+Minetest World Format 22...25
+=============================
+
+This applies to a world format carrying the block serialization version
+22...25, used at least in
+- 0.4.dev-20120322 ... 0.4.dev-20120606 (22...23)
+- 0.4.0 (23)
+- 24 was never released as stable and existed for ~2 days
+
+The block serialization version does not fully specify every aspect of this
+format; if compliance with this format is to be checked, it needs to be
+done by detecting if the files and data indeed follows it.
+
+Legacy stuff
+=============
+Data can, in theory, be contained in the flat file directory structure
+described below in Version 17, but it is not officially supported. Also you
+may stumble upon all kinds of oddities in not-so-recent formats.
+
+Files
+======
+Everything is contained in a directory, the name of which is freeform, but
+often serves as the name of the world.
+
+Currently the authentication and ban data is stored on a per-world basis.
+It can be copied over from an old world to a newly created world.
+
+World
+|-- auth.txt ----- Authentication data
+|-- env_meta.txt - Environment metadata
+|-- ipban.txt ---- Banned ips/users
+|-- map_meta.txt - Map metadata
+|-- map.sqlite --- Map data
+|-- players ------ Player directory
+|   |-- player1 -- Player file
+|   '-- Foo ------ Player file
+`-- world.mt ----- World metadata
+
+auth.txt
+---------
+Contains authentication data, player per line.
+  <name>:<password hash>:<privilege1,...>
+Format of password hash is <name><password> SHA1'd, in the base64 encoding.
+
+Example lines:
+- Player "celeron55", no password, privileges "interact" and "shout":
+    celeron55::interact,shout
+- Player "Foo", password "bar", privilege "shout":

+Map File Format
+================
+
+Minetest maps consist of MapBlocks, chunks of 16x16x16 nodes.
+
+In addition to the bulk node data, MapBlocks stored on disk also contain
+other things.
+
+History
+--------
+We need a bit of history in here. Initially Minetest stored maps in a
+format called the "sectors" format. It was a directory/file structure like
+this:
+  sectors2/XXX/ZZZ/YYYY
+For example, the MapBlock at (0,1,-2) was this file:
+  sectors2/000/ffd/0001
+
+Eventually Minetest outgrow this directory structure, as filesystems were
+struggling under the amount of files and directories.
+
+Large servers seriously needed a new format, and thus the base of the
+current format was invented, suggested by celeron55 and implemented by
+JacobF.
+
+SQLite3 was slammed in, and blocks files were directly inserted as blobs
+in a single table, indexed by integer primary keys, oddly mangled from
+coordinates.
+
+Today we know that SQLite3 allows multiple primary keys (which would allow
+storing coordinates separately), but the format has been kept unchanged for
+that part. So, this is where it has come.
+</history>
+
+So here goes
+-------------
+map.sqlite is an sqlite3 database, containg a single table, called
+"blocks". It looks like this:
+
+  CREATE TABLE `blocks` (`pos` INT NOT NULL PRIMARY KEY,`data` BLOB);
+
+The key
+--------
+"pos" is created from the three coordinates of a MapBlock using this
+algorithm, defined here in Python:
+
+  def getBlockAsInteger(p):
+      return int64(p[2]*16777216 + p[1]*4096 + p[0])
+  
+  def int64(u):
+      while u >= 2**63:
+          u -= 2**64
+      while u <= -2**63:
+          u += 2**64
+      return u
+  
+It can be converted the other way by using this code:
+
+  def getIntegerAsBlock(i):
+      x = unsignedToSigned(i % 4096, 2048)
+      i = int((i - x) / 4096)
+      y = unsignedToSigned(i % 4096, 2048)
+      i = int((i - y) / 4096)
+      z = unsignedToSigned(i % 4096, 2048)
+      return x,y,z
+  
+  def unsignedToSigned(i, max_positive):
+      if i < max_positive:
+          return i
+      else:
+          return i - 2*max_positive
+
+The blob
+---------
+The blob is the data that would have otherwise gone into the file.
+
+See below for description.
+
+MapBlock serialization format
+==============================
+NOTE: Byte order is MSB first (big-endian).
+NOTE: Zlib data is in such a format that Python's zlib at least can
+      directly decompress.
+
+u8 version
+- map format version number, this one is version 22
+
+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.
+  - 0x08: generated: True if the block has been generated. If false, block
+    is mostly filled with CONTENT_IGNORE and is likely to contain eg. parts
+    of trees of neighboring blocks.
+
+u8 content_width
+- Number of bytes in the content (param0) fields of nodes
+if map format version <= 23:
+    - Always 1
+if map format version >= 24:
+    - Always 2
+
+u8 params_width
+- Number of bytes used for parameters per node
+- Always 2
+
+zlib-compressed node data:
+if content_width == 1:
+    - content:
+      u8[4096]: param0 fields
+      u8[4096]: param1 fields
+      u8[4096]: param2 fields
+if content_width == 2:
+    - content:
+      u16[4096]: param0 fields
+      u8[4096]: param1 fields
+      u8[4096]: param2 fields
+- The location of a node in each of those arrays is (z*16*16 + y*16 + x).
+
+zlib-compressed node metadata list
+- content:
+  u16 version (=1)
+  u16 count of metadata
+  foreach count:
+    u16 position (p.Z*MAP_BLOCKSIZE*MAP_BLOCKSIZE + p.Y*MAP_BLOCKSIZE + p.X)
+    u16 type_id
+    u16 content_size
+    u8[content_size] (content of metadata)
+
+- Node timers
+if map format version == 23:
+  u8 unused version (always 0)
+if map format version == 24: (NOTE: Not released as stable)
+  u8 nodetimer_version
+  if nodetimer_version == 0:
+    (nothing else)
+  if nodetimer_version == 1:
+    u16 num_of_timers
+    foreach num_of_timers:
+      u16 timer position (z*16*16 + y*16 + x)
+      s32 timeout*1000
+      s32 elapsed*1000
+
+u8 static object version:
+- Always 0
+
+u16 static_object_count
+
+foreach static_object_count:
+  u8 type (object type-id)
+  s32 pos_x_nodes * 10000
+  s32 pos_y_nodes * 10000
+  s32 pos_z_nodes * 10000
+  u16 data_size
+  u8[data_size] data
+
+u32 timestamp
+- Timestamp when last saved, as seconds from starting the game.
+- 0xffffffff = invalid/unknown timestamp, nothing should be done with the time
+               difference when loaded
+
+u8 name-id-mapping version
+- Always 0
+
+u16 num_name_id_mappings
+
+foreach num_name_id_mappings
+  u16 id
+  u16 name_len
+  u8[name_len] name
+
+- Node timers
+if map format version == 25:
+  u8 length of the data of a single timer (always 2+4+4=10)
+  u16 num_of_timers
+  foreach num_of_timers:
+    u16 timer position (z*16*16 + y*16 + x)
+    s32 timeout*1000
+    s32 elapsed*1000
+
+EOF.
+
+Format of nodes
+----------------
+A node is composed of the u8 fields param0, param1 and param2.
+
+if map format version <= 23:
+    The content id of a node is determined as so:
+    - If param0 < 0x80,
+        content_id = param0
+    - Otherwise
+        content_id = (param0<<4) + (param2>>4)
+if map format version >= 24:
+    The content id of a node is param0.
+
+The purpose of param1 and param2 depend on the definition of the node.
+
+The name-id-mapping

+eg. 'ToolItem WPick 21323'
+
+Inventory serialization format
+-------------------------------
+- The inventory serialization format is line-based
+- The newline character used is "\n"
+- The end condition of a serialized inventory is always "EndInventory\n"
+- All the slots in a list must always be serialized.

+==============================================
+Minetest World Format used as of 2011-05 or so
+==============================================
+
+Map data serialization format version 17.
+
+0.3.1 does not use this format, but a more recent one. This exists here for
+historical reasons.
+
+Directory structure:
+sectors/XXXXZZZZ or sectors2/XXX/ZZZ
+XXXX, ZZZZ, XXX and ZZZ being the hexadecimal X and Z coordinates.
+Under these, the block files are stored, called YYYY.
+
+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.
+
+The MapBlock file format (sectors2/XXX/ZZZ/YYYY):
+-------------------------------------------------
+
+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

+    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 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 = 3
+
+- Here's a quick untested connect-disconnect done in PHP:
+# host: ip of server (use gethostbyname(hostname) to get from a dns name)
+# port: port of server
+function check_if_minetestserver_up($host, $port)
+{
+	$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
+	$timeout = array("sec" => 1, "usec" => 0);

+		# We got a reply! read the peer id from it.
+		$peer_id = substr($buf, 9, 2);
+		
+		# Disconnect
+		$buf = "\x4f\x45\x74\x03".$peer_id."\x00\x00\x03";
