 ==== Format
 
 This describes the elements of the INI file format:
 
 * *Sections*: Section declarations start with '[' and end with ']' as in [section1] and [section2] above. And sections start with section declarations.
-* *Parameters*: The "var1 = foo" above is an example of a parameter (also known as an item). Parameters are made up of a key ('var1'), equals sign ('='), and a value ('foo').
+* *Parameters*: The "var1 = foo" above is an example of a parameter (also known as an item). Parameters are made up of a key ('var1'), equals sign ('='), and a value ('foo'). Multiline is support if value of parameter is enclosed by ".

 * <b>Duplicate sections</b>: Duplicate sections will be merged. Parameters duplicated between to the two sections follow the duplicate parameters rule above.
 * *Parameters*: The parameter separator character can be specified when an +IniFile+ is created.
