+How this works: 
+
+- craft it by filling the right and left row with glass; place in the middle row (from top to bottom): steel, mese, steel
+- place the travelnet box somewhere
+- right-click on it; enter name of the station (e.g. "my house", "center of desert city") and name of the network (e.g. "intresting towns","my buildings")
+- punch it to update the list of stations on that network
+- right-click to use the travelbox
+
+An unconfigured travelnet box can be configured by anyone. If it is misconfigured, just dig it and place it anew.
+All stations that have the same network name set and are owned by the same user connect to the same network.

+
+ Version: 2.2 (with optional abm for self-healing)
+    
+ Please configure this mod in config.lua
+
+ Changelog:
+ 05.10.14 - Added an optional abm so that the travelnet network can heal itshelf in case of loss of the savefile.
+            If you want to use this, set
+                  travelnet.enable_abm = true
+            in config.lua and edit the interval in the abm to suit your needs.
+ 19.11.13 - moved doors and travelnet definition into an extra file
+          - moved configuration to config.lua
+ 05.08.13 - fixed possible crash when the node in front of the travelnet is unknown
+ 26.06.13 - added inventory image for elevator (created by VanessaE)
+ 21.06.13 - bugfix: wielding an elevator while digging a door caused the elevator_top to be placed
+          - leftover floating elevator_top nodes can be removed by placing a new travelnet:elevator underneath them and removing that afterwards
+          - homedecor-doors are now opened and closed correctly as well
+          - removed nodes that are not intended for manual use from creative inventory
+          - improved naming of station levels for the elevator
+ 21.06.13 - elevator stations are sorted by height instead of date of creation as is the case with travelnet boxes
+          - elevator stations are named automaticly
+ 20.06.13 - doors can be opened and closed from inside the travelnet box/elevator
+          - the elevator can only move vertically; the network name is defined by its x and z coordinate
+ 13.06.13 - bugfix
+          - elevator added (written by kpoppel) and placed into extra file
+          - elevator doors added
+          - groups changed to avoid accidental dig/drop on dig of node beneath
+          - added new priv travelnet_remove for digging of boxes owned by other players
+          - only the owner of a box or players with the travelnet_remove priv can now dig it
+          - entering your own name as owner_name does no longer abort setup
+ 22.03.13 - added automatic detection if yaw can be set
+          - beam effect is disabled by default
+ 20.03.13 - added inventory image provided by VanessaE
+          - fixed bug that made it impossible to remove stations from the net
+          - if the station a player beamed to no longer exists, the station will be removed automaticly
+          - with the travelnet_attach priv, you can now attach your box to the nets of other players
+          - in newer versions of Minetest, the players yaw is set so that he/she looks out of the receiving box
+          - target list is now centered if there are less than 9 targets
