+# Welcome to Evennia!
+
+This is your game directory, set up to let you start with
+your new game right away. An overview of this directory is found here:
+https://github.com/evennia/evennia/wiki/Directory-Overview#the-game-directory
+
+You can delete this readme file when you've read it and you can
+re-arrange things in this game-directory to suit your own sense of
+organisation (the only exception is the directory structure of the
+`server/` directory, which Evennia expects). If you change the structure
+you must however also edit/add to your settings file to tell Evennia
+where to look for things.
+
+Your game's main configuration file is found in
+`server/conf/settings.py` (but you don't need to change it to get
+started). If you just created this directory (which means you'll already
+have a `virtualenv` running if you followed the default instructions),
+`cd` to this directory then initialize a new database using
+
+    evennia migrate
+
+To start the server, stand in this directory and run
+
+    evennia start
+
+This will start the server, logging output to the console. Make
+sure to create a superuser when asked. By default you can now connect
+to your new game using a MUD client on `localhost`, port `4000`.  You can
+also log into the web client by pointing a browser to
+`http://localhost:4001`.
+
+# Getting started
+
+From here on you might want to look at one of the beginner tutorials:
+http://github.com/evennia/evennia/wiki/Tutorials.
+
+Evennia's documentation is here:
+https://github.com/evennia/evennia/wiki.
+
+Enjoy!

+This folder holds modules for implementing one's own commands and
+command sets. All the modules' classes are essentially empty and just
+imports the default implementations from Evennia; so adding anything
+to them will start overloading the defaults. 
+
+You can change the organisation of this directory as you see fit, just
+remember that if you change any of the default command set classes'
+locations, you need to add the appropriate paths to
+`server/conf/settings.py` so that Evennia knows where to find them.
+Also remember that if you create new sub directories you must put
+(optionally empty) `__init__.py` files in there so that Python can
+find your modules.

+This directory holds files used by and configuring the Evennia server 
+itself.
+
+Out of all the subdirectories in the game directory, Evennia does
+expect this directory to exist, so you should normally not delete,
+rename or change its folder structure.
+
+When running you will find four new files appear in this directory: 
+
+ - `server.pid` and `portal.pid`: These hold the process IDs of the
+   Portal and Server, so that they can be managed by the launcher. If
+   Evennia is shut down uncleanly (e.g. by a crash or via a kill
+   signal), these files might erroneously remain behind. If so Evennia
+   will tell you they are "stale" and they can be deleted manually.
+ - `server.restart` and `portal.restart`: These hold flags to tell the
+   server processes if it should die or start again. You never need to
+   modify those files.
+ - `evennia.db3`: This will only appear if you are using the default
+   SQLite3 database; it a binary file that holds the entire game
+   database; deleting this file will effectively reset the game for
+   you and you can start fresh with `evennia migrate` (useful during
+   development).  
+
+## server/conf/
+
+This subdirectory holds the configuration modules for the server. With
+them you can change how Evennia operates and also plug in your own
+functionality to replace the default. You usually need to restart the
+server to apply changes done here. The most important file is the file
+`settings.py` which is the main configuration file of Evennia. 
+
+## server/logs/
+
+This subdirectory holds various log files created by the running
+Evennia server. It is also the default location for storing any custom
+log files you might want to output using Evennia's logging mechanisms.

+should be returned. The inlinefunc should never cause a traceback.

+never accepted as a valid call - this is only intended to be used
+internally by Evennia, notably to send the `session` keyword to
+the function; this is the session of the object viewing the string

+     basetype_setup()     - only called once, used for behind-the-scenes
+                            setup. Normally not modified.
+     basetype_posthook_setup() - customization in basetype, after the object
+                            has been created; Normally not modified.
+
+     at_object_creation() - only called once, when object is first created.
+                            Object customizations go here.
+     at_object_delete() - called just before deleting an object. If returning
+                            False, deletion is aborted. Note that all objects
+                            inside a deleted object are automatically moved
+                            to their <home>, they don't need to be removed here.
+
+     at_init()            - called whenever typeclass is cached from memory,
+                            at least once every server restart/reload
+     at_cmdset_get(**kwargs) - this is called just before the command handler
+                            requests a cmdset from this object. The kwargs are
+                            not normally used unless the cmdset is created
+                            dynamically (see e.g. Exits).
+     at_pre_puppet(account)- (account-controlled objects only) called just
+                            before puppeting
+     at_post_puppet()     - (account-controlled objects only) called just
+                            after completing connection account<->object
+     at_pre_unpuppet()    - (account-controlled objects only) called just
+                            before un-puppeting
+     at_post_unpuppet(account) - (account-controlled objects only) called just
+                            after disconnecting account<->object link
+     at_server_reload()   - called before server is reloaded
+     at_server_shutdown() - called just before server is fully shut down
+
+     at_access(result, accessing_obj, access_type) - called with the result
+                            of a lock access check on this object. Return value
+                            does not affect check result.
+
+     at_before_move(destination)             - called just before moving object
+                        to the destination. If returns False, move is cancelled.
+     announce_move_from(destination)         - called in old location, just
+                        before move, if obj.move_to() has quiet=False
+     announce_move_to(source_location)       - called in new location, just
+                        after move, if obj.move_to() has quiet=False
+     at_after_move(source_location)          - always called after a move has
+                        been successfully performed.
+     at_object_leave(obj, target_location)   - called when an object leaves
+                        this object in any fashion
+     at_object_receive(obj, source_location) - called when this object receives
+                        another object
+
+     at_traverse(traversing_object, source_loc) - (exit-objects only)
+                              handles all moving across the exit, including
+                              calling the other exit hooks. Use super() to retain
+                              the default functionality.
+     at_after_traverse(traversing_object, source_location) - (exit-objects only)
+                              called just after a traversal has happened.
+     at_failed_traverse(traversing_object)      - (exit-objects only) called if
+                       traversal fails and property err_traverse is not defined.
+
+     at_msg_receive(self, msg, from_obj=None, **kwargs) - called when a message
+                             (via self.msg()) is sent to this obj.
+                             If returns false, aborts send.
+     at_msg_send(self, msg, to_obj=None, **kwargs) - called when this objects
+                             sends a message to someone via self.msg().
+
+     return_appearance(looker) - describes this object. Used by "look"
+                                 command by default
+     at_desc(looker=None)      - called by 'look' whenever the
+                                 appearance is requested.
+     at_get(getter)            - called after object has been picked up.
+                                 Does not stop pickup.
+     at_drop(dropper)          - called when this object has been dropped.
+     at_say(speaker, message)  - by default, called if an object inside this
+                                 object speaks

+     ndb - non-persistent attribute handler: same as db but does not
+                        create a database entry when storing data
+
+    * Helper methods
+
+     start() - start script (this usually happens automatically at creation
+               and obj.script.add() etc)
+     stop()  - stop script, and delete it
+     pause() - put the script on hold, until unpause() is called. If script
+               is persistent, the pause state will survive a shutdown.
+     unpause() - restart a previously paused script. The script will continue
+                 from the paused timer (but at_start() will be called).
+     time_until_next_repeat() - if a timed script (interval>0), returns time
+                 until next tick
+
+    * Hook methods (should also include self as the first argument):
+
+     at_script_creation() - called only once, when an object of this
+                            class is first created.
+     is_valid() - is called to check if the script is valid to be running
+                  at the current time. If is_valid() returns False, the running
+                  script is stopped and removed from the game. You can use this
+                  to check state changes (i.e. an script tracking some combat
+                  stats at regular intervals is only valid to run while there is
+                  actual combat going on).
+      at_start() - Called every time the script is started, which for persistent
+                  scripts is at least once every server start. Note that this is
+                  unaffected by self.delay_start, which only delays the first
+                  call to at_repeat().
+      at_repeat() - Called every self.interval seconds. It will be called
+                  immediately upon launch unless self.delay_start is True, which
+                  will delay the first call of this method by self.interval
+                  seconds. If self.interval==0, this method will never
+                  be called.
+      at_stop() - Called as the script object is stopped and is about to be
+                  removed from the game, e.g. because is_valid() returned False.
+      at_server_reload() - Called when server reloads. Can be used to
+                  save temporary variables you want should survive a reload.

+    """
+    Find shortest paths from the  start vertex to all vertices nearer than or equal to the end.
+
+    The input graph G is assumed to have the following representation:
+    A vertex can be any object that can be used as an index into a dictionary.
+    G is a dictionary, indexed by vertices.  For any vertex v, G[v] is itself a dictionary,
+    indexed by the neighbors of v.  For any edge v->w, G[v][w] is the length of the edge.
+    This is related to the representation in <http://www.python.org/doc/essays/graphs.html>
+    where Guido van Rossum suggests representing graphs as dictionaries mapping vertices
+    to lists of outgoing edges, however dictionaries of edges have many advantages over lists:
+    they can store extra information (here, the lengths), they support fast existence tests,
+    and they allow easy modification of the graph structure by edge insertion and removal.
+    Such modifications are not needed here but are important in many other graph algorithms.
+    Since dictionaries obey iterator protocol, a graph represented as described here could
+    be handed without modification to an algorithm expecting Guido's graph representation.
+
+    Of course, G and G[v] need not be actual Python dict objects, they can be any other
+    type of object that obeys dict protocol, for instance one could use a wrapper in which vertices
+    are URLs of web pages and a call to G[v] loads the web page and finds its outgoing links.
+
+    The output is a pair (D,P) where D[v] is the distance from start to v and P[v] is the
+    predecessor of v along the shortest path from s to v.
+
+    Dijkstra's algorithm is only guaranteed to work correctly when all edge lengths are positive.
+    This code does not verify this property for all edges (only the edges examined until the end
+    vertex is reached), but will correctly compute shortest paths even for some graphs with negative
+    edges, and will raise an exception if it discovers that a negative edge has caused it to make a mistake.

+Prototypes
+
+A prototype is a simple way to create individualized instances of a
+given typeclass. It is dictionary with specific key names.
+
+For example, you might have a Sword typeclass that implements everything a
+Sword would need to do. The only difference between different individual Swords
+would be their key, description and some Attributes. The Prototype system
+allows to create a range of such Swords with only minor variations. Prototypes
+can also inherit and combine together to form entire hierarchies (such as
+giving all Sabres and all Broadswords some common properties). Note that bigger
+variations, such as custom commands or functionality belong in a hierarchy of
+typeclasses instead.
+
+A prototype can either be a dictionary placed into a global variable in a
+python module (a 'module-prototype') or stored in the database as a dict on a
+special Script (a db-prototype). The former can be created just by adding dicts
+to modules Evennia looks at for prototypes, the latter is easiest created
+in-game via the `olc` command/menu.
+
+Prototypes are read and used to create new objects with the `spawn` command
+or directly via `evennia.spawn` or the full path `evennia.prototypes.spawner.spawn`.
+
+A prototype dictionary have the following keywords:
+
+Possible keywords are:
+- `prototype_key` - the name of the prototype. This is required for db-prototypes,
+  for module-prototypes, the global variable name of the dict is used instead
+- `prototype_parent` - string pointing to parent prototype if any. Prototype inherits
+  in a similar way as classes, with children overriding values in their partents.
+- `key` - string, the main object identifier.
+- `typeclass` - string, if not set, will use `settings.BASE_OBJECT_TYPECLASS`.
+- `location` - this should be a valid object or #dbref.
+- `home` - valid object or #dbref.
+- `destination` - only valid for exits (object or #dbref).
+- `permissions` - string or list of permission strings.
+- `locks` - a lock-string to use for the spawned object.
+- `aliases` - string or list of strings.
+- `attrs` - Attributes, expressed as a list of tuples on the form `(attrname, value)`,
+  `(attrname, value, category)`, or `(attrname, value, category, locks)`. If using one
+   of the shorter forms, defaults are used for the rest.
+- `tags` - Tags, as a list of tuples `(tag,)`, `(tag, category)` or `(tag, category, data)`.
+-  Any other keywords are interpreted as Attributes with no category or lock.
+   These will internally be added to `attrs` (eqivalent to `(attrname, value)`.
+
+See the `spawn` command and `evennia.prototypes.spawner.spawn` for more info.
