+## Signs Module
+
+The Signs Module can be used by plugin authors to create interactive
+signs - that is - signs which display a list of choices which can be
+changed by interacting (right-clicking) with the sign.
+
+### signs.menu() function
+
+This function is used to construct a new interactive menu on top of an
+existing sign in the game world.
+
+#### Parameters
+
+ * Label : A string which will be displayed in the topmost line of the
+   sign. This label is not interactive.  
+ * options : An array of strings which can be selected on the sign by 
+   right-clicking/interacting.
+ * callback : A function which will be called whenever a player
+   interacts (changes selection) on a sign. This callback in turn
+   takes as its parameter, an object with the following properties...
+
+   * player : The player who interacted with the sign.
+   * sign : The [org.bukkit.block.Sign][buksign] which the player interacted with.
+   * text : The text for the currently selected option on the sign.
+   * number : The index of the currently selected option on the sign.
+ 
+ * selectedIndex : optional: A number (starting at 0) indicating which
+   of the options should be selected by default. 0 is the default.
+
+#### Returns
+This function does not itself do much. It does however return a
+function which when invoked with a given
+[org.bukkit.block.Sign][buksign] object, will convert that sign into
+an interactive sign.
+
+#### Example: Create a sign which changes the time of day.
+
+##### plugins/signs/time-of-day.js
+    
+    var utils = require('utils'),
+        signs = require('signs');
+
+    var onTimeChoice = function(event){
+        var selectedIndex = event.number;
+        // convert to Minecraft time 0 = Dawn, 6000 = midday, 12000 = dusk, 18000 = midnight
+        var time = selectedIndex * 6000; 
+        event.player.location.world.setTime(time);
+    };
+
+    // signs.menu returns a function which can be called for one or more signs in the game.
+    var convertToTimeMenu = signs.menu('Time of Day',
+        ['Dawn', 'Midday', 'Dusk', 'Midnight'],
+        onTimeChoice);
+        
+    exports.time_sign = function( player ){
+
+        var sign = signs.getTargetedBy(player);
+        if (!sign){
+            throw new Error('You must look at a sign');
+        } 
+        convertToTimeMenu(sign);
+    };
+
+To use the above function at the in-game prompt, look at an existing
+sign and type...
+
+    /js time_sign(self);
+
+... and the sign you're looking at will become an interactive sign
+which changes the time each time you interact (right-click) with it.
+
+### signs.getTargetedBy() function
+
+This function takes a [org.bukkit.entity.LivingEntity][bukle] as a
+parameter and returns a [org.bukkit.block.Sign][buksign] object which
+the entity has targeted. It is a utility function for use by plugin authors.
+
+#### Example
+
+     var signs = require('signs'),
+         utils = require('utils');
+     var player = utils.player('tom1234');
+     var sign = signs.getTargetedBy( player );
+     if (!sign){ 
+        player.sendMessage('Not looking at a sign');
+     }
