+beginning. Hit any player action key to increment turns (they will not trigger
+the actions usually mapped to them, only repeat the actions done at that point
+in the game as defined in the "record" file). Keys to manage windows, scroll on
+the map and quit the program do their usual thing. Append a number to the -s
+option (like "-s100") to start the recording at the respective turn number.
+
+Hacking / server internals and configuration
+--------------------------------------------
+
+The ./confserver/world file defines the map object types, actions available to
+them and the map itself. Each definition consists of a multi-line block wherein
+each line sets one attribute of the object type, action or the map.
+
+Here's a typical map definition block:
+
+MAP_TYPE 0
+HEIGHT 64
+WIDTH 64
+DIST_ORTHOGONAL 5
+DIST_DIAGONAL 7
+
+A line of "MAP_TYPE" followed by a non-empty token starts the map definition
+block. In the future, the second token may differentiate different map types,
+but as of right now, only one is available and the value is not interpreted.
+The numbers after "HEIGHT" and "WIDTH" give the map's vertical and horizontal
+extensions in cells. They must be >= 1 and <= 256. The numbers after
+"DIST_ORTHOGONAL" and "DIST_DIAGONAL" define the diagonal movement penalty as
+the second value divided by the first. The above values define a penalty ratio
+of 7/5 or 1.4, i.e. it takes 40% longer in turns to move diagonally than
+orthogonally. Set both to the same value to eliminate the diagonal movement
+penalty. A negative penalty to realize weird geometry is possible by setting
+"DIST_DIAGONAL" to a lower value than "DIST_ORTHOGONAL". Both values, however,
+must be >= 1 and <= 255.
+
+Here's a typical action definition block:
+
+ACTION 1
+NAME move
+EFFORT 5
+
+A line of "ACTION" followed by a number starts an action definition block and
+sets the action's id for internal use to 1. The number after "EFFORT" determines
+how many turns this action takes for the actor performing it. The string after
+"NAME" names the action. Furthermore, if it is one of "move", "pick_up", "drop"
+or "use", it matches internal functions described by these strings to this
+action. All other names (including "wait") currently are matched to a do-nothing
+wait function.
+
+Here's a typical map object type definition block:
+
+OBJECT 2
+NAME ZOMBIE
+SYMBOL z
+LIFEPOINTS 3
+CORPSE_ID 5
+CONSUMABLE 0
+
+A line of "OBJECT" followed by a number starts it, and the number sets the
+object type's internal id. The number after "CONSUMABLE" defines the object
+as consumable (and to so many hitpoints gain). The character after "SYMBOL" is
+the one shown on the map to represent to object type. "LIFEPOINTS" is the start
+hitpoints value for this object type and defines it as animate if it is
+non-zero. The string after "NAME" sets the object type's name. "CORPSE_ID" sets
+the id of the object type that objects of this type degrade to if their
+hitpoints drop to zero if they start out as inanimate (what is not implemented
+yet: or if they are inanimate, but are otherwise crushed). Note that the
+"CORPSE_ID" must match the id of an object type defined in the file (before or
+after, it may even be the same).
+
+All these definition block members must be present within their blocks, but only
+"ACTION" / "OBJECT" / "MAP_TYPE" must be positioned at their respective blocks'
+first line; the others may appear in whatever order and even multiple times. If
+an object or action definition block is finished, however, it cannot be
+re-defined by starting a new block with the same object type or action id.
+
+Tokens in this config file are separated by whitespace. Single quotes can be
+put around string values that are to include whitespace by themslves. Note that
+all numbers must be decimal representations of unsigned 8 bit integers, i.e.
+>= 0 and < 256 and sans preceding "+".
+
+All source files are thoroughly documented to explain more details of
+plomrogue's internals. The ./roguelike-server executable can be run with a -v
+option for helpful debugging info (mostly: what messages the client sends to the
+server). Server and client communicate via files in the ./server/ directory
+(generated when the server is first run). The ./server/in file is read by the
+server for newline-delimited commands. The ./server/out file contains server
+messages to be read by clients. The ./server/worldstate file contains a
+serialized representation of the game world's data as it is to be visible to
+the player / the player's client.
