The parsimony package
Deprecated. Parsimony is a generalized and simplified version of the industrial-strength parser combinator library Parsec. Like Parsec, it is simple, safe, well documented, convenient, with good error messages, and fast. In addition, Parsimony adds support for working with differet types of input such as byte strings (for compat input representation) and lazy byte strings (for parsing large amounts of data). It also supports working with text in different character encodings such as UTF8.
