+jQuery.ime Input method specification
+=====================================
+
+Input methods are defined in javascript files. An input method is a javascript
+object and it is passed to $.ime.register() method to register with jquery.ime
+
+eg: $.ime.register( hebrewStandardKeyboard );
+
+Metadata fields
+---------------
+
+id: A mandatory unique identifier that represents the input method.
+eg: "hindi-inscript"
+
+name: A mandatory short name for the input method. eg: Hindi InScript
+
+description: An optional short description about the input method.
+eg: "keyboard layout as per inscript standard"
+
+date: An optional string to represent when this input method was written.
+Format should be: yyyy-mm-dd
+
+author: An optional string containing the authors name. Can contain email
+address as well. eg: "Santhosh Thottingal, <santhosh.thottingal@gmail.com>"
+
+URL: An optional string containing URL for the original input method definition.
+
+license: An optional string containing licence information. Eg: "CC-BY-SA" or
+"GPLv3".
+
+version: An optional string containing version information.
+
+Input method definition
+-----------------------
+
+patterns: A regular expression table that maps the original inputs to the
+target language.
+
+eg:
+patterns: [
+		[ 'q', '/' ],
+		[ 'w', '\'' ],
+		[ 'e', 'ק' ],
+		[ 'r', 'ר' ],
+		[ 't', 'א' ],
+		[ 'y', 'ט' ],
+		[ 'u', 'ו' ],
+		[ 'i', 'ן' ],
+		[ 'o', 'ם' ],
+		[ 'p', 'פ' ]
+		...
+		// These characters are mirrored in RTL languages
+		[ '\\(', ')' ],
+		[ '\\)', '(' ],
+		[ '\\[', ']' ],
+		[ '\\]', '[' ]
+	]
+
+Any valid regular expression is possible as first element of each array item.
+More examples
+	[ '([ക-ഹ])a', '$1ാ' ]
+	[ '(([ൺ-ൿം])\u200c+)?I', '$2ഐ' ]
+
+In the above example, $1, $1 etc are according to the normal regular expression
+replace syntax.
+
+The second member of pattern can be a function as well. For eg:
+
+patterns: [ [ '[a-z]', function ( $1 ) {
+			return $1.toUpperCase();
+		} ] ]
+
+This rule replace all key strokes to its upper case character.
+
+contextLength: Length of the context to remember. jquery.ime can replace the
+text based on the previously typed characters. eg:
+
+	[ 'ൿh', 'c', 'ച്' ]
+
+Note that this pattern definition has 3 members, the middle one is the context.
+This rule is interpreted as 
+
+The current key is h, previous key is c. For the previous key press c, we have
+a transliteration ൿ. But if it is followed by h and ൿ is indeed from key press
+c, replace ൿh with ച്
+
+To make this work, we need to remember the previous key strokes. How many of
+them we need to remember? contextLength should have that value.
+
+This is optional field with default value 0. ie, we don't remember previous key
+strokes by default.
+
+maxKeyLength: While trying to find possible matches, we need to know how many
+characters from the current typing location(cursor) should be used before
+giving up.
+
+maxKeyLength defines it. Normally it is the length of largest regex sequence in
+the patterns.
+
+This field is optional and default value is 1.
