Source Code for Package jazzparser.parsers

 1  """Parser modules for the Jazz Parser. 
 2   
 3  Subpackages of this define parser modules. Each may implement its own  
 4  parsing algorithm and operates independently of the formalism and  
 5  tagger, which have strictly defined interfaces through which the parser  
 6  accesses them. 
 7   
 8  To add a new parser, create the parser class in a new subpackage and  
 9  add the package's name to the PARSERS constant below.
