+which should be enough in most use cases. Of course more combinators can be added if necessary! 
+Most of the parser combinators have the same behavior as their Haskell counterparts. 
+@code{parsec} also comes with a simple error handling mechanism so that it can display an error message showing how the parser fails.")
