public class TaggedReader
extends Reader

This reader extracts meta information from the data header.

The syntax for an entry is

 '$$$' ws* key ws* '=' value '\n'
 value = string | quoted_string
 quoted_string = '"' [ char | escape ]* '"'
 

Meta data is scanned until the first line not starting with '$$$'. So the first character returned is the first character on the first line not starting with '$$$'.
