+//	It has 3 control characters '{', '}' and '"'. Names and values may be quoted or
+//	not. The quote '"' character must not be used within name or values, only for
+//	quoting whole tokens. You may use escape sequences wile parsing and add within a
+//	quoted token a \" to add quotes within your name or token. When using Escape
+//	Sequence the parser must now that by setting KeyValues::UsesEscapeSequences( true ),
+//	which it's off by default. Non-quoted tokens ends with a whitespace, '{', '}' and '"'.
+//	So you may use '{' and '}' within quoted tokens, but not for non-quoted tokens.
+//  An open bracket '{' after a key name indicates a list of subkeys which is finished
+//  with a closing bracket '}'. Subkeys use the same definitions recursively.
+//  Whitespaces are space, return, newline and tabulator. Allowed Escape sequences
+//	are \n, \t, \\, \n and \". The number character '#' is used for macro purposes
+//	(eg #include), don't use it as first character in key names.
