-        - The <b>activation type</b> deals with what happens to the Pickup as soon as it is picked up. It can either be set to <em>immediate</em>, which means that the Pickup is activated/used immediately upon being picked up. Or to <em>onUse</em>, which means, that the Pickup will be activated/used if some outside entity (most commonly the player through the PickupInventory) decides to use it.
-        - The <b>duration type</b> deals with whether the Pickup has a continuous effect or whether its effect is focused on a singular instant. It can either be set to <em>once</em>, which means, that the Pickup just has an effect (at a singular instant in time) and is done once that effect has been applied. Or to <em>continuous</em>, which means that the effect of the Pickup unfolds over some timespan.

It is only populated on the server (or in standalone mode). Each @ref orxonox::PickupRepresentation "PickupRepresentation" that is generated through XML registers itself with the PickupManager and is thereby added to the list.
         - The @ref orxonox::PickupManager::representationsNetworked_ "representationsNetworked_" list is the networked (hence the name) equivalent to the @ref orxonox::PickupManager::representations_ "representations_" list. It links an objectId of a @ref orxonox::PickupRepresentation "PickupRepresentation" to a @ref orxonox::PickupRepresentation "PickupRepresentation". This list is maintained on all hosts, each representation registers itself (in its constructor) with the PickupManager. Since the representations are synchronised they are created on each host. The "same" instance on each host is identified by the same objectId and that is why we store the representations with the objectId as key. We can then use this list to get a @ref orxonox::PickupRepresentation "PickupRepresentation" for a specific @ref orxonox::Pickupable "Pickupable" (or more precisely a number identifiying that particular pickup, but we'll see that, when we look at the next list) on a client to be used in the PickupInventory.

This list is maintained on all hosts, a new container is inserted when a @ref orxonox::Pickupable "Pickupable" is picked up, but only if it has been picked up by the repsective host. This list is then used by the PickupInventory to access the required information and to get the correct @ref orxonox:.PickupRepresentation "PickupRepresentation".

It is only maintained by the server (or in standalone mode), to be able to use, unuse and drop @ref orxonox::Pickupable "Pickupables" through the PickupInventory. Since @ref orxonox::Pickupable "Pickupables" only exist on the server a client that wants to change a pickups status has so send a request over the network (with the number identifying the pickup) to the server and then the server facilitates the change, using this list to map from the identifyer to the actual @ref orxonox::Pickupable "Pickupable".
         - The @ref orxonox::PickupManager::indexes_ "indexes_" list links a @ref orxonox::Pickupable "Pickupable" to the number identifying it. This is only maintained on the server (or in standalone mode), and is used for the inverse mapping of the previous list, which means the server uses it identify pickups on clients when it communicates changes in pickups to clients.

     @brief
-        The Health Pickup is a Pickupable that can do (dependent upon the parameters) lots of different things to the health of a Pawn.
-        There are 4 parameters that can be chosen:
-        - The <b>health</b> The amount of health that (in a way dependent on the other parameters) is transferred to the Pawn.
-        - The <b>activation type</b> It can be chosen to be either <em>immediate</em> or <em>onUse</em>. The activation type essentially (as indicated by the name) defines when the health is transferred, either immediately after being picked up or only after the player uses it.
-        - The <b>duration type</b> It can be chosen to be either <em>once</em> or <em>continuous</em>. For <em>once</em> the specified health is transferred once to the Pawn, for <em>continuous</em> the set health is transferred over a span of time at a rate defined by the health rate parameter.
-        - The <b>health type</b> The health type can be chosen to be <em>limited</em>, <em>temporary</em> or <em>permanent</em>. <em>limited</em> means that the health is increased only to the maximum health of the Pawn. 'temporary' means that the maximum health is temporarily elevated but will be set back as soon as the pickup is no longer in use. <em>permanent</em> means that the maximum health of the Pawn is increased such that the health provided by the pickup will fit in and the maximum health stays that way.

         A Pickup which can manipulate the Speed of a Pawn.
 
-        There are 4 parameters that can be cosen:
-        - The @b speed @b multiplier
-        - The @b additional (forward) @b speed
-        - The @b activation @b type 'immediate' or 'onUse'. defines if the item is used when it's picked up or only after the player chooses to use it.
-        - The @b duration The activation time of the pickup.
+        There are 5 parameters that can be cosen:
+        - The @b speedMultiply, specifies a factor by which the Spaceships speed is multiplied. The default is 1.
+        - The @b speedAdd, specifies a value that is added to the speed of the Spaceship. The default is 0.
+        - The @b activationType <em>immediate</em> or <em>onUse</em>, defines if the SpeedPickup is used when it's picked up or only after the player chooses to use it. The default is <em>immediate</em>.
+        - The @b durationType Can be either <em>once</em> or <em>continuous</em>. For <em>once</em> the SpeedPickup is just active for as long as it is used, for <em>continuous</em> the SpeedPickup is active only for the specified duration. The default is <em>once</em>.
+        - The @b duration The time in seconds the SpeedPickup is active at the most. The default is 0.
+
+        An example, how a SpeedPickup could be defined in XML could be:
+        @code
+        <SpeedPickup
+            speedMultiply = 2.0
+            speedAdd = 10.0
+            activationType = "immediate"
+            durationType = "continuous"
+            duration = 30.0
