 Fields
 ==================
+Every field can have case insensitive name which should not contain '.' (because it is reserved for links to structure field values) and '#'(because it is also reserver for inside usage).
+Field name must not be started by a number or chars '$' and '_'. *Field names are case insensitive!*

-Field names
-============
-You can use any chars for field names but you can't use '.' in names (because the special char is used as the separator in field paths) and a name must not be started with a number. Also you must not use the symbols '$' and '_' as the first char in the name because they are used by the parser for special purposes.

 Commentaries
 =============
 You can use commentaries inside a parser script, the parser supports the only comment format and recognizes as commentaries all text after '//' till the end of line.
