This is an open source library for parsing text-based inputs. PARSER makes use of context-free
grammars to validate and parse sentences. Having specified such a grammar, the library takes care of parsing
text-based inputs and returns a tree of nodes that represents the parsed sentence. Furthermore, it provides
ways for interpreting and refining the returned tree of nodes. In essence, the library aims to remove the
pain of parsing and instead allow focusing on processing and interpreting parsed results.
