 1) The config file for NoCheatPlus is called "config.yml" now.

 2) You can have different config files for different worlds. To achieve this, 
    copy the "config.yml" and rename the copy to "worldname_config.yml". Set-
    tings in that file will now only affect the world with the name "worldname".
    You may also delete all settings from that world-specific file that you 
    won't use. They'll be implicitly taken from the master "config.yml" file.

 3) If you have files named "config.txt", "default_actions.txt" or "actions.txt"
    please delete them. They are no longer used by NoCheatPlus and serve no purpose
    anymore.

 4) Never change the amount of white-spaces in front of options in the config 
    file "config.yml". It will break the configuration.

 NoCheatPlus allows to define in detail what should happen when a player fails a
 check in form of "actions". There are 4 possible things that may be done.
 (read on to learn in detail on how to define/modify actions):

  cancel: The effects of the action "cancel" depend on the check that it is
          used for. Usually it means to prevent something from happening,
          e.g. stop an attack or prevent sending of a chat message.

  log:    Create and show/log a message. Log messages can be customized in
          how often, when and where they are registered/shown.

  cmd:    Execute a command of Bukkit or another plugin as if it were typed 
          into the server console by an admin. Like logging, these can be
          customized.

  vl>X:   Is meant to symbolize "violation level at least X". Used to define
          actions that will be executed only if players reached a certain 
          violation level. Failing a check usually increases their "vl", not
          failing checks reduces it over time. Violation levels mean different
          things for different checks, e.g. they may describe moved distance
          beyond the limit, number of attacks above the attack limit, sent
          messages beyond the spam limit.

#                       How to customize your "actions"                        #
#                                                                              #
################################################################################

 1) The "cancel" action is just the word "cancel". Read in the detailed option
    description to find out what it does depending on the check that it is
    assigned to.

 2) The "log" action is a string of the form "log:string:delay:repeat:target".

    log:    is simply used to let NoCheatPlus know it is a log action. Don't remove
            it from the action, or NoCheatPlus will not know what it is and how to
            handle it.

    string: is the message that will be logged. Because there is so little
            space here, you only give a name here and define the actual
            log message in the "strings" section of the config file.

    delay:  a number declaring how many times that action initially has to be 
            executed before it really leads to logging a message. Use this for 
            situations where it's common to have false positives in checks and 
            you only want the log message to be shown if a player fails the 
           check multiple times within a minute.

    repeat: a number declaring how many seconds have to pass after logging the
            message before it will be logged again for that player. This is 
            needed to prevent "log-spam". Usually a value of 5 seconds is 
            acceptable, for rare events you can use lower values. It is very
            recommended to at least use the value 1 (one second) here.

    target: where should the message be logged to? You can use three letters 
            here. The order that you use is not important.
            "c" means logging to console
            "i" means logging to ingame chat and 
            "f" means logging to the log file.

 3) The "cmd" action is a string of the form "cmd:string:delay:repeat".

    cmd:   is simply used to let NoCheatPlus know it is a command action. Don't
           remove it from the action, or NoCheatPlus will not know what it is and 
           how to handle it.

   string: is the command that will be issued. Because there is so little space
           here, you only give a name here and define the actual command in the
           "strings" section of the config file.

   delay:  a number declaring how many times that action initially has to be 
           executed before it really leads to running the command in the 
           console. Use this to create e.g. a 3-strikes-law by setting it to 3.
           Only if a player fails the check 3 times within 1 minute, the 
           command will be really run.

   repeat: a number declaring how many seconds have to pass after running the
           command before it can be run again for that player. Because many
           commands are expensive (take time, resources), you may want to limit
           how often they can be called.

 4) The "vl>" isn't really an action. It limits all actions that are written
    afterwards to be only executed if the players violation level has reached
    at least the given value. This allows to define layers of actions and
    handle repeated or severe failing of checks different. For example the spam
    check will only kick players if they reach a certain violation level (vl).

 NoCheatPlus only supports "SuperPerms", CraftBukkits official permission framework.
 You'll need to use a permissions plugin that supports "SuperPerms" to use it 
 with NoCheatPlus. Here are some I know of: 

 - bPermissions
 - PermissionsEx
 - Essentials GroupManager

 I personally recommend bPermissions, but any of them will do just fine.

 By default all these permissions are set to "op", which means players with 
 OP-status have all permissions, unless you change it.


--------------------------------------------------------------------------------
----------------------- Permissions for ADMINISTRATION -------------------------
--------------------------------------------------------------------------------

 - nocheatplus.admin.chatlog
    The player will receive log messages that are directed at the "ingame chat"
    as a normal chat message ingame.

 - nocheatplus.admin.commands
    The player gets access to some of the "/nocheatplus" commands

 - nocheatplus.admin.reload
    In combination with "nocheatplus.admin.commands", the player gets access to the
    "/nocheatplus reload" command, which will cause NoCheatPlus to reread its config
    files.


--------------------------------------------------------------------------------
--------------------------- Permissions for CHECKS -----------------------------
--------------------------------------------------------------------------------

 These permission nodes are grouped the same way as the options in the config
 file, based on the event type they belong to. The logic is, that a player 
 having one of these nodes means he will NOT be checked. Players without the
 permission node will be checked. 

 Example: A player has permission "nocheatplus.checks.moving.morepackets". That 
 means he is allowed to use that hack/cheat because NoCheatPlus won't check/stop it.


------------------------ MOVING Permissions for CHECKS -------------------------

 - nocheatplus.checks.moving.runfly
    Allows the player to move freely. It also treats the player as if he has
    the ".flying", ".swimming", ".sneaking" and ".nofall" permission too.
    
 - nocheatplus.checks.moving.flying
    Allows the player to fly, independent of if he is in "creative mode" or not.
    He will be limited in speed by the config settings "flyingspeedvertical"
    and "flyingspeedhorizontal". It also treats the player as if he has the
    ".nofall" permission too.

 - nocheatplus.checks.moving.swimming
    Allows the player to swim as fast as he is allowed to walk. Normally a
    player swims slower than he walks and NoCheatPlus prevents faster movement in
    water.

 - nocheatplus.checks.moving.sneaking
    Allows the player to sneak faster than he is allowed to walk. Normally a
    player sneaks a lot slower than he walks and NoCheatPlus prevents faster
    movement while sneaking.

 - nocheatplus.checks.moving.nofall
    Allows the player to avoid fall damage by using hacks. Normally NoCheatPlus
    will keep track of a players movement and try to rectify the fall-damage
    calculations of Minecraft in case they seem to be wrong because of players
    tricking the server.

 - nocheatplus.checks.moving.morepackets
    Allows players to make a lot more movements than normally possible. Doing
    more movements will result in faster overall movement speed and causes the
    server to spend a lot of additional time for processing these movements.
    
 - nocheatplus.checks.moving.morepacketsvehicle
   Allows players to make a lot more movements (while being in a vehicule) than
   normally possible. Doing more movements will result in faster overall movement
   speed and causes the server to spent a lot of additional time for processing
   these movements.
   
 - nocheatplus.checks.moving.boatonground
   Allows players to place boats on the ground (and not only on the water).
   
 - nocheatplus.checks.moving.respawntrick
   Allows player to respawn on top if they are blocked by a gravel or a sand
   block (instead of removing the blocks blocking them). This is usually used
   by players to go quickly to the surface when they are in their mines).


-------------------- BLOCKBREAK Permissions for CHECKS -------------------------

 - nocheatplus.checks.blockbreak.fastbreak
    Allows the player to break blocks very quickly.

 - nocheatplus.checks.blockbreak.reach
    Allows the player to break blocks that are further away than usual.

 - nocheatplus.checks.blockbreak.direction
    Don't force players to look at the blocks that they try to destroy.

 - nocheatplus.checks.blockbreak.noswing
    Don't force players to swing their arm when breaking blocks.


-------------------- BLOCKPLACE Permissions for CHECKS -------------------------

 - nocheatplus.checks.blockplace.fastplace
    Allows the player to place blocks very quickly.

 - nocheatplus.checks.blockplace.reach
    Allows the player to place blocks that are further away than usual.

 - nocheatplus.checks.blockplace.direction
    Don't force players to look at the blocks that they try to place.
 
 - nocheatplus.checks.blockplace.projectile
   Allows the player to throw projectiles very quickly, like expbottles, eggs,
   monster eggs, eyes of ender, ender pearls. This is usually used by griefers
   to level up very quickly or to crash the server by spawning too much mobs.
   
 - nocheatplus.checks.blockplace.autosign
   Allows the player to place multiple signs with the same text. This is usually
   used by griefers to place quickly a lot of signs with their signature.


--------------------- INVENTORY Permissions for CHECKS -------------------------

 - nocheatplus.checks.inventory.drop
    Don't limit the number of items that a player may drop within a short time

 - nocheatplus.checks.inventory.instantbow
    Don't prevent players from shooting their bows instantly without taking the
    usual time to pull the string back

 - nocheatplus.checks.inventory.instanteat
    Don't prevent players from eating their food instantly without taking the
    usual time to munch on it


----------------------- CHAT Permissions for CHECKS ----------------------------

 - nocheatplus.checks.chat.spam
    Don't limit the number of messages and commands that a player may send in a
    short timeframe

 - nocheatplus.checks.chat.color
    Don't filter color codes from messages that get sent by players, allowing
    them to use colors in their messages.

    Don't force players to look at their targets while fighting

 - nocheatplus.checks.fight.noswing
    Don't force players to move their arms while fighting

 - nocheatplus.checks.fight.reach
    Don't limit the distance for fights

 - nocheatplus.checks.fight.speed
    Don't limit the number of attacks that the player can do per second

 - nocheatplus.checks.fight.godmode
    Don't prevent the player from keeping the temporary invulnerability that he
    gets when taking damage

 - nocheatplus.checks.fight.instantheal
    Don't prevent the player from accellerating their health generation by
    food saturation


--------------------------------------------------------------------------------
---------------------------- Permissions for MODS ------------------------------
--------------------------------------------------------------------------------

    Don't prevent the player from using all other Zombe's cheats
 
 - nocheatplus.mods.cjb.fly
    Don't prevent the player from using CJB's fly mod
 
 - nocheatplus.mods.cjb.xray
    Don't prevent the player from using CJB's xray

    Don't prevent the player from using Rei's Minimap's cave mode
    
 - nocheatplus.mods.rei.radar
    Don't prevent the player from using Rei's Minimap's radar

 - nocheatplus.mods.mcautomap
    Don't prevent the player from using all Minecraft AutoMap's cheats


--------------------------------------------------------------------------------
---------------------- Things to know about Permissions ------------------------
--------------------------------------------------------------------------------

 NoCheatPlus defines "parent" nodes for all permissions already for you. That means
 you can use one of the following:

 - nocheatplus
 - nocheatplus.admin
 - nocheatplus.checks
 - nocheatplus.checks.moving
 - nocheatplus.checks.blockbreak
 - nocheatplus.checks.blockplace
 - nocheatplus.checks.inventory
 - nocheatplus.checks.chat
 - nocheatplus.checks.fight
 - nocheatplus.mods
 - nocheatplus.mods.zombe
 - nocheatplus.mods.cjb
 - nocheatplus.mods.rei
 - nocheatplus.mods.mcautomap

 To give a player all the permissions that start with that permission node.
 
 Especially you don't have to and should not use ".*" anywhere when defining
 NoCheatPlus permissions.
 
 
 You can exclude a specific player from getting logged by appending ".silent"
 to the relevant permission node of the specific check. E.g. 
 
 - nocheatplus.checks.moving.nofall.silent
 
 will prevent NoCheatPlus from recording log messages for that player for the
 "nofall" check, while still executing all other actions as usual. These silent
 permissions won't show up elsewhere, e.g. when using the "nocheatplus permlist"
 command.

################################################################################

 Here you'll find the whole list of settings that you can manipulate in the 
 config.yml file. It is further split into logical sections


--------------------------------------------------------------------------------
----------------------------- CLIENT MODS Section ------------------------------
--------------------------------------------------------------------------------

 Everything that in has to do with the client mods can be found at this part of
 the config.yml.
 
  allow:
  
    Allow all your players to use all the client mods (Zombe, CJB, Rei's Minimap,
    Minecraft AutoMap).

--------------------------------------------------------------------------------
-------------------------------- LOGGING Section -------------------------------
--------------------------------------------------------------------------------

 Everything that in general has to do with controlling NoCheatPluss logging can be
 found at this part of the config.yml

  active:

    Should messages get logged at all. If you are not interested in messages, 
    set this to false and you'll hear and see (almost) nothing of NoCheatPlus.

  prefix:

    Will be placed in front of many log messages. To get colors, use "&" 
    followed by a number (0-9) or a letter (A-F). E.g. "&7NCP&f:" would produce
    the letters NCP in red (&7), followed by black text (&f).

  filename:

    The name of the logfile that NoCheatPlus will use to log its messages. The
    default name is "nocheatplus.log", but you can use a different one if you want
    to.

  file:

    Should the logfile be used at all. Set to false if you don't want to use
    the logfile. By default the logfile will be used (true).

  console:

    Should the server console be used to display messages. Set to false if you
    don't want NoCheatPlus to show messages related to checks in the console. Error
    messages may still get displayed there though.

  ingamechat:

    Should NoCheatPlus display messages in the ingame chat? Set to false if you
    don't want NoCheatPlus to show messages ingame. The messages will only be seen
    by players with the permission node "nocheatplus.admin.chatlog" or if you don't
    use a permissions plugin, by players who are OP.

  showactivechecks:

    Should NoCheatPlus display lists of checks that are enabled for each world. Set
    to true if you are unsure that your (multiworld) setup of the config files
    is done correctly.

  debugmessages:

    Should some additional messages be displayed in the server console, e.g. 
    about NoCheatPlus encountering lag. The displayed messages may change from
    version to version. This is deactivated by default.    


--------------------------------------------------------------------------------
-------------------------------- CHECKS Section --------------------------------
--------------------------------------------------------------------------------

 Everything that in has to do with the various checks that NoCheatPlus runs on the
 players. Use these to specify what will be done, how it will be done and what
 happens if somebody fails checks.


----------------------------- INVENTORY Subsection -----------------------------

 Checks that at least technically have to do with the inventory or usage of
 items can be found here.

 1) DROP:

     The "inventory.drop" check. It limits how many separate items a player can 
     drop onto the ground within a specific time. Dropping a lot of separate 
     items at once can cause lag on the server, therefore this check exists.

      active:
        Should the check be enabled. Set to false if you are not interested in 
        this at all

      time:
        Over how many seconds should dropped items be counted, before the 
        counter gets reset and starts at zero again.

      limit:
        How many items may be dropped in the timeframe that is specified by
        the "time" setting. Please consider that dying causes a player to drop
        up to 36 separate items (stacks). Therefore this value shouldn't be 
        set below ~50.

      actions:
        What should happen when a player goes beyond the set limit. Default 
        settings log a message and kick the player from the server. The VL of
        the drop check symbolizes how many items a player dropped beyond the
        set limit. If the limit is 100 and he tried to drop 130, he will have a
        Violation Level of 130 - 100 = 30.

 2) INSTANTBOW:

     Players may attack extremely fast and with a fully charged bow without
     waiting for it to be fully pulled back. This is a significant advantage in
     PvP and PvE combat.

      active:
        Should players be checked for this behavior. Set to false if you don't
        care about players using bows faster than normally possible.

      actions:
        What should happen if the player fails this check. Default is to stop
        the attack ("cancel" it) and log messages. The Violation Level (VL) for
        this check the time difference between how long it took the player to
        fire an arrow and how long NoCheatPlus thinks he should have taken, in
        1/10 seconds. Therefore a VL of 10 would mean that the player shot an
        arrow 1 second faster than NoCheatPlus expected. The VL gets increased with
        every failed check and slowly decreased for every passed check.

 3) INSTANTEAT:

     Players may eat various kinds of food instantly instead of waiting the
     usual time munching on the item.

      active:
        Should players be checked for this behavior. Set to false if you don't
        care about players eating their food faster than normally possible.

      actions:
        What should happen if the player fails this check. Default is to stop
        the eating ("cancel" it) and log messages. The Violation Level (VL) for
        this check the time difference between how long it took the player to
        eat his food and how long NoCheatPlus thinks he should have taken, in
        1/10 seconds. Therefore a VL of 10 would mean that the player ate his
        food 1 second faster than NoCheatPlus expected. The VL gets increased with
        every failed check and slowly decreased for every passed check.


------------------------------ MOVING Subsection -------------------------------

 Checks that at least technically have to do with the player moving around or
 impacting the world with his movement can be found here.

 1) RUNFLY:

     Players may move in illegal ways (flying, running too fast) or try to
     trick the server into thinking that they are not falling/flying by
     cleverly manipulating the data that they send to the server.

      active:
        Should players get checked for this type of movement related hacks at 
        all. If deactivated, player may freely move around on the server, fly
        or run really fast.

      walkspeed:
        How fast should the player be allowed to walk. Default is "100", 
        meaning 100% of normal walking speed. You will not see this option in
        your config.yml file, because normally you shouldn't have to change the
        walking speed of players at all (NoCheatPlus knows when players sprint, use
        Swiftness potions etc and will already adapt the speed based on that
        data).

      sprintspeed:
        How fast should the player be allowed to sprint. Default is "100", 
        meaning 100% of normal sprinting speed. You will not see this option in
        your config.yml file, because normally you shouldn't have to change the
        sprinting speed of players at all (NoCheatPlus knows when players sprint,
        use Swiftness potions etc and will already adapt the speed based on 
        that data).

      sneakspeed:
        How fast should the player be allowed to sneak. Default is "100", 
        meaning 100% of normal sneaking speed. You will not see this option in
        your config.yml file, because normally you shouldn't have to change the
        sneaking speed of players at all (NoCheatPlus knows when players sprint,
        use Swiftness potions etc and will already adapt the speed based on 
        that data).

      swimspeed:
        How fast should the player be allowed to swim. Default is "100", 
        meaning 100% of normal swimming speed. You will not see this option in
        your config.yml file, because normally you shouldn't have to change the
        swimming speed of players at all (NoCheatPlus knows when players sprint,
        use Swiftness potions etc and will already adapt the speed based on 
        that data).

      allowfastsneaking:
        Should sneaking players be allowed to move as fast as normal players.
        Set this to true, if you use plugins that enable players to do that 
        (e.g. the "Heroes" plugin or other RPG plugins tend to do that)

      actions:
        What should happen when a player sneaks/swims/walks/runs faster than
        normally allowed or is flying. Default is to log messages (depending on
        how severe the cheating is) and teleport the player to the last known
        legitimate location on ground that NoCheatPlus can remember for that player
        ("cancel" the movement)

      checknofall:
        Should players be checked for a common type of "nofall" hack, that 
        allows them to avoid taking damage when falling. If you don't care
        about fall damage, you can deactivate this. It gets deactivated if a
        player is allowed to fly (see some lines below), because it doesn't
        make sense to allow flying and then hurt players when they land.

      nofallaggressivemode:
        Enable an improved version of nofall check, that will catch additional
        types of "nofall" hacks and deal damage to players directly. This is
        usually safe to activate. It will only work if the "checknofall" is
        also set to "true".

      nofallactions:
        What should happen if a player is considered to be using a "nofall"
        hack. Default reaction is to log a message and encourage Bukkit to deal
        fall damage anyway ("cancel" the hack). The Violation Level is the
        fall distance in blocks that the player tried to avoid. It gets
        increased every time that the player fails the check, and decreased 
        over time if the player doesn't fail the check.
        
      TRACKER:
        This is an entire subsection dedicated to a recently introduced check
        specially designed to prevent players from staying in the air longer
        than a defined value.
        
         active:
           Should players get checked for this type of movement related hacks at 
           all. If deactivated, player may stay in the air without being noticed
           by NoCheat+.
           
         maxtime:
           The maximum interval (in milliseconds) before kicking the player who
           flies (it takes less than 6000 ms to fall from Y = 256 to Y = 0);

      FLYING:
        This is an entire subsection dedicated to the "moving.flying" check.
        It will be used instead of the "runfly" check whenever a player has
        the right to fly.

         allowflyingalways:
           Should all players be allowed to fly always.

        allowflyingincreative:
          Should players that are set to "creative mode" be allowed to fly. If
          they are already allowed because of "allowflyingalways" to fly, this
          setting gets ignored.

        flyingspeedlimithorizontal:
          How many 1/100 blocks may a player fly horizontal within one "step".
          The official "creative mode" flying reaches speeds of about 0.6 
          blocks which means a value of 60 here.

        flyingspeedlimitvertical:
          How many 1/100 blocks may a player fly vertically up within one 
          "step". A value of 100 which means 1 block seems reasonable for most
          cases.

        flyingheightlimit:
          What is the maximum height (in blocks) that a player may reach by 
          flying, relative to the max world height he is in. Some servers
          experience lag when players fly very, very high. This value is how
          far above the map height a player may fly.

        actions:
          What should happen if a player flies faster/higher than defined here?
          Default is to log messages and to prevent the player from moving
          ("cancel" his last movement). The Violation Level (VL) of this check
          is the distance that the player went beyond what NoCheatPlus allowed him.
          The VL increases with every failed check and slowly decreases for
          every passed check.

 2) MOREPACKETS:

     The morepackets check is complementary to the "runfly" check. While the
     "runfly" check(s) limit the distance a player can move per step, this
     "morepackets" check limits the number of "steps" a player may take per 
     second. A normal value is 20 steps per second.

      active:
        Should players be checked for this kind of cheating. If you are not 
        interested in players that cheat that way, set this to false. It is a
        good idea to have this active, because players that cheat by sending
        more packets than normally allowed may lag the server (each of those
        packets has to be processed, after all).

      actions:
        What should happen if a player is considered to be cheating by taking 
        more steps per second than normal. Default is to log messages and 
        teleport the player back to a location where he was ~1 second before
        ("cancel" his movement). The Violation Level VL is the number of
        packets that the player sent beyond the expected amount.
        
 3) MOREPACKETSVEHICULE:

     The morepacketsvehicule check is complementary to the "morepackets" check.
     While the "morepacket" check limit the number of player-move packets send
     per second, this "morepacketsvehicle" limit the number of vehicule-move
     packets sent per second. A normal value is 20 packets per second.

      active:
        Should players be checked for this kind of cheating. If you are not 
        interested in players that cheat that way, set this to false. It is a
        good idea to have this active, because players that cheat by sending
        more packets than normally allowed may lag the server (each of those
        packets has to be processed, after all).

      actions:
        What should happen if a player is considered to be cheating by taking 
        more steps per second than normal. Default is to log messages and break
        the boat the player is using. The Violation Level VL is the number of
        packets that the player sent beyond the expected amount.
       
 4) WATERWALK:
 
     The waterwalk check is used to prevent players from walking on water using
     a client dedicated to griefing (this mode is usually called Jesus mod).
     Firstly, it'll check if the player's move is valid (not only moving the X
     and Z axes but also on the Y axis and, of course, if the player is near the
     surface (most of the griefing client set the player 0.3 blocks under the
     water surface). Secondly, it'll make sure the player is using the borders
     of the block to climb outside the water (it prevents players using griefing
     clients to simply jump multiple times over the water).
     
      active:
        Should players be checked for this kind of cheating. If you are not
        interested in players that cheat that way, set this to false. It is a
        good idea to have this active, because player won't be able to cross
        easily the oceans.
        
      actions:
	    What should happen if a player is considered to be cheating by walking
        on water. Default is to log messages and to prevent the player from moving
        ("cancel" his last movement). The Violation Level (VL) of this check is
        the distance between the player and the surface or how far away he is from
        the normal position if a player climbing a block. The VL increases with
        every failed check and slowly decreases for every passed check.


---------------------------- BLOCKBREAK Subsection -----------------------------

 Checks that at least technically have to do with the player breaking blocks.
 
 1) FASTBREAK:
 
     This check will prevent players from breaking blocks too quickly by checking
     the interval of time elapsed since they've broken their last block. This
     should prevent players from using the features called "Smasher", "Click
     Nuker" and "Creative Nuker" of their griefing client.
     
      active:
        Should players be checked for this behaviour.
        
      actions:
        What should happen if the player is considered to cheat this way. The
        default is to prevent him from breaking the block ("cancel" breaking)
        and on repeated offenses to log messages about it. If the Violation
        Level becomes too hight, the player will be kicked. The Violation Level
        (VL) is the difference between the usual minimum time it takes to break
        two blocks and the real time elapsed. The VL increases with every failed
        attempt to break a block, and decreases with every successful attempt.
 

 2) REACH:

     Players may slightly increase the distance at which they can break 
     blocks. This check will try to identify that by comparing player and 
     block location.

      active:
        Should players be checked for this behaviour.

      actions:
        What should happen if the player is considered to cheat this way. The
        default is to prevent him from breaking the block ("cancel" breaking)
        and on repeated offenses to log messages about it. The Violation Level
        (VL) is the distance in Blocks between the reach distance that NoCheatPlus
        allowed and what the player actually tried to use. The VL increases 
        with every failed attempt to break a block out of reach, and decreases
        with every successful attempt.

 3) DIRECTION:

     Players may break blocks without really looking at them. This is often 
     combined with breaking a lot of blocks surrounding the player at the same
     time.

      active:
        Should players get checked for this type of hack

      precision:
        How strict should NoCheatPlus be when comparing the players line of view 
        with the broken block location. The value represents (roughly) the 
        amount of 1/100 blocks that the player is allowed to look past the to 
        be broken block. 50 (0.5 blocks) seems a good default value.

      penaltytime:
        If a player fails this check, how long should he be prevented from 
        breaking blocks afterwards, in milliseconds. This is intended to make
        automated destruction of blocks harder. 0.3 seconds (value 300) is the
        default. Set to 0, if you don't want to limit players at all after
        failing this check.

      actions:
        What should happen if a player fails this check. Default is to prevent
        the breaking of the block ("cancel" it) and after repeated/more severe
        offenses to log a message. The Violation Level (VL) for this check is
        the distance in Blocks between the line of view of the player and the
        block. It increases with every failure and decreases with every 
        successful block break.

 4) NOSWING:

     Players may break blocks without moving their arm. This is confusing for
     nearby players, as they won't see who broke the blocks.

      active:
        Should players get checked for this type of hack

      actions:
        What should happen if the player didn't swing his arm first? Default is
        to log a message and prevent the breaking of the block ("cancel" it).
        The Violation Level (VL) is the number of block-break attempts without
        first swinging the arm. It increases with every failed attempt by 1 and
        decreases with every successful attempt slowly.


---------------------------- BLOCKPLACE Subsection -----------------------------

 Checks that at least technically have to do with the player placing blocks.
 
 1) FASTPLACE:
 
     This check will prevent players from placing blocks too quicly by checking
     the interval of time elapsed since they've placed their last block. This
     should prevent players from using the features called "FastPlace" and
     "Build" of their griefing client.
     
      active:
        Should players be checked for this behaviour.
        
      actions:
        What should happen if the player is considered to cheat this way. The
        default is to prevent him from placing the block ("cancel" placing)
        and on repeated offenses to log messages about it. If the Violation
        Level becomes too hight, the player will be kicked. The Violation Level
        (VL) is the difference between the usual minimum time it takes to place
        two blocks and the real time elapsed. The VL increases with every failed
        attempt to place a block, and decreases with every successful attempt.

 2) REACH:

     Players may slightly increase the distance at which they can place 
     blocks. This check will try to identify that by comparing player and 
     block location.

      active:
        Should players be checked for this behaviour.

      actions:
        What should happen if the player is considered to cheat this way. The
        default is to prevent him from placing the block ("cancel" placing)
        and on repeated offenses to log messages about it. The Violation Level
        (VL) is the distance in Blocks between the reach distance that NoCheatPlus
        allowed and what the player actually tried to use. The VL increases 
        with every failed attempt to place a block out of reach, and decreases
        with every successful attempt.

 3) DIRECTION:

     Players may place blocks without really looking at them. This is often 
     combined with placing a lot of blocks in a certain shape.

      active:
        Should players get checked for this type of hack.

      precision:
        How strict should NoCheatPlus be when comparing the players line of view 
        with the placed block location. The value represents (roughly) the 
        amount of 1/100 blocks that the player is allowed to look past the to 
        be placed block. 75 (0.75 blocks) seems a good default value.

      penaltytime:
        If a player fails this check, how long should he be prevented from 
        placing blocks afterwards, in milliseconds. This is intended to make
        automated placing of blocks harder. 0.1 second (value 100) is the
        default. Set to 0, if you don't want to limit players at all after
        failing this check.

      actions:
        What should happen if a player fails this check. Default is to prevent
        the placing of the block ("cancel" it) and after repeated/more severe
        offenses to log a message. The Violation Level (VL) for this check is
        the distance in Blocks between the line of view of the player and the
        block. It increases with every failure and decreases with every 
        successful block placement.
        
 4) PROJECTILE
 
      Players may throw projectiles (experience bottles, eggs, monster eggs, 
      eyes of ender, ender pearls) really quickly in order to crash the server.
      
       active:
        Should players get checked for this type of hack.
        
       interval:
        The time (in milliseconds) between each thrown projectile. It takes
        more than 150 ms if the player is keeping its right button pressed.
        
       actions:
        What should happen if a player fails this check. Default is to prevent
        the placing of the block ("cancel" it) and after repeated/more severe
        offenses to log a message and kick the player. The Violation Level (VL)
        for this check is the interval elapsed subtracted to the interval defined
        in the configuration's file; It increases with every failure and decreases
        with every successfully thrown projectile.


------------------------------- CHAT Subsection --------------------------------

 Checks that at least technically have to do with chat or commands.

 1) COLOR:

     Players may use color-codes to send colored messages. This may be used
     to fool other players into believing they are admins or similar.

      active:
        Should player messages get checked for the use of color codes.

      actions:
        What should be done if a player sends messages with color codes.
        Default is to log a message and prevent ("cancel") the use of the
        color codes, by filtering them from the message. The message itself
        will still be transmitted. The Violation Level (VL) for this check is
        the number of messages that contained color codes. It increases with
        each color-code message by 1 and decreases slowly with colorless
        messages.

 2) SPAM:

     Players may send a ton of messages/commands in a short time to cause
     lag or even crash a server.

      active:
        Should player messages get checked for sending of too many messages.

      whitelist:
        A " " (whitespace) separated list of words. Messages that start with
        these sequences will not be counted. This is ideal to exempt commands
        from getting filtered, by e.g. adding "/help" to the list.

      timeframe:
        For how many seconds should messages and commands be counted, before 
        the counters get reset and counting starts at zero again.

      messagelimit:
        How many "normal" chat messages may be sent within the timeframe. All
        messages that don't start with "/" are considered "normal".

      commandlimit:
        How many commands may be issued within the timeframe. Some mods (e.g.
        TooManyItems) send a command on every mouse-click, which may cause
        problems if this is set too low. So choose wisely. Every message that
        starts with "/" is considered a command, even if the command doesn't
        exist.

      actions:
        What should happen if players send more messages/commands than declared
        by the above limits? Default is to prevent the message/command from 
        being processed ("cancel" them) and for severe cases where players send
        a lot of messages/commands, kick them. The Violation Level (VL) is the
        number of messages/commands that were sent beyond the specified limits.
        It gets increased for every message/command by 1 and reset to zero when
        the "timeframe" has passed.


------------------------------ FIGHT Subsection --------------------------------

 Checks that at least technically have to do with direct combat.

 1) DIRECTION:

     Players may attack other players and creatures without really looking at
     them. This is often combined with automatically attacking every living
     thing within reach ("kill-aura"). This check will check if the attacker
     looks at his target.

      active:
        Should players get checked for this type of hack

      precision:
        How strict should NoCheatPlus be when comparing the players line of view 
        with the his target's location. The value represents (roughly) the 
        amount of 1/100 blocks that the player is allowed to look past the to 
        be attacked entity. 75 (0.75 blocks) seems a good default value.

      penaltytime:
        If a player fails this check, how long should he be prevented from 
        attacking stuff afterwards, in milliseconds. This is intended to make
        automated attacking of enemies harder. 0.5 second (value 500) is the
        default. Set to 0, if you don't want to limit players at all after
        failing this check.

      actions:
        What should happen if a player fails this check. Default is to prevent
        the attack from happening ("cancel" it) and after repeated/more severe
        offenses to log a message. The Violation Level (VL) for this check is
        the distance in Blocks between the line of view of the player and the
        target. It increases with every failure and decreases with every 
        successful attack.
        
 2) NOSWING:

     Players may attack entities without moving their arm. This is confusing
     for nearby players, as they won't see who is attacking them or the nearby
     creatures.

      active:
        Should players get checked for this type of hack

      actions:
        What should happen if the player didn't swing his arm first? Default is
        to log a message and prevent the attack from happening ("cancel" it).
        The Violation Level (VL) is the number of attacking attempts without
        first swinging the arm. It increases with every failed attempt by 1 and
        decreases with every successful attempt slowly.
        
 3) REACH:

     Players may slightly increase the distance at which they can attack enemy
     creatures/players. This check will try to identify that by comparing 
     player and target location.

      active:
        Should players be checked for this behaviour.

      distance:
        How far can the enemy be away from the attacker, in 1/100 Blocks. The
        default value of 400, which is 4.00 blocks seems to work fine most of
        the time. Increase if you get to many false positives to e.g. 425 or
        450.

      penaltytime:
        If a player fails this check, how long should he be prevented from 
        attacking stuff afterwards, in milliseconds. This is intended to make
        automated attacking of enemies harder. 0.5 second (value 500) is the
        default. Set to 0, if you don't want to limit players at all after
        failing this check.

      actions:
        What should happen if the player is considered to cheat this way. The
        default is to prevent him from attacking the target ("cancel" attack)
        and on repeated offenses to log messages about it. The Violation Level
        (VL) is the distance in Blocks between the reach distance that NoCheatPlus
        allowed and what the player actually tried to use. The VL increases 
        with every failed attempt to attack enemies out of reach, and decreases
        with every successful attempt.

 4) SPEED:

     Players may be attacking extremely fast within a short time by using
     automated clicking or hacks. This is an advantage in many situations.
     
      active:
        Should players be checked for this behavior.

      attacklimit:
        How many attacks may a player start within 1 second. Consider setting
        this to a value that's close to how fast you believe players can click
        their mouse. The default is 15 per second.

      actions:
        What should happen if the player fails this check. Default is to stop
        the attack ("cancel" it) and log messages. The Violation Level (VL) is
        the number of attacks beyond the set limit. For each failed check it
        is increased by 1 and it gets decreased for every successful attack.

 5) GODMODE:

     Players may trick Bukkit into not dealing them damage when they get
     attacked. This will try to identify and correct that behavior.

      active:
        Should players be checked for this behavior.

      actions:
        What should happen if the player fails this check. Default is to make
        him vulnerable to the attack ("cancel" his "godmode") and log messages.
        The Violation Level (VL) for this check is the number of ticks that the
        player seemingly tried to stay invulnerable. A second has 20 ticks.
        Every time the player fails the check, the VL gets increased by the
        amount of ticks (but at most 15 per failed check), and everytime the
        player didn't avoid taking damage it gets reduced slowly.

 6) INSTANTHEAL:

     Players may trick Bukkit into regenerating their health faster when they
     are satiated (full food bar) than normally possible. This will try to
     identify and correct that behaviour.

      active:
        Should players be checked for this behavior.

      actions:
        What should happen if the player fails this check. Default is to not
        allow the health regeneration ("cancel" the regeneration) and log a
        message. The Violation LEvel (VL) for this check is the number of
        seconds that the player tried to skip while regenerating health. It
        gets reduced whenever the player regenerates health while obeying the
        normal regeneration times.


--------------------------------------------------------------------------------
------------------------------- STRINGS Section --------------------------------
--------------------------------------------------------------------------------

  This is the section that defines various strings for "log" or "cmd" actions.
  Each has a name (the part in front of ":") and a definition (the part behind
  the ":"). Whenever you use a "log" or "cmd" action in one of the "actions: " 
  options of this config file, the string will be taken from this section. 
  Arbitrary many additional strings may be defined here, or existing strings
  may be changed.

  Most messages/commands use place-holders in [ ], which will be replaced at
  runtime with relevant information. Some of these may only be available in
  certain circumstances, only "[player]" can be used everywhere, especially
  in "cmd" actions.

- NoCheatPlus isn't perfect and won't prevent all forms of cheating. It's a best
  effort approach. 

- NoCheatPlus may make mistakes. Don't see everything NoCheatPlus says or does as
  indisputable fact that somebody cheated. It's not possible to be 100% sure
  if somebody is cheating or not, NoCheatPlus will try to be right most of the
  time.
