-description		lexical and syntactic parser generator for Python
-long_description	Toy Parser Generator is a lexical and syntactic parser \
-				generator for Python. With a very clear and simple \
-				syntax, you can write an attributed grammar that is \
-				translated into a recursive descendant parser. TPG \
-				generated code is very closed to the original grammar. \
-				This means that the parser works like the grammar. A \
-				grammar rule can be seen as a method of the parser \
-				class, symbols as method calls, attributes as method \
-				parameters and semantic values as return values. You \
-				can also add Python code directly into grammar rules \
-				and build abstract syntax trees while parsing.
