+efficient, expressive, and reusable parsers suitable for high-performance
+applications.  It exposes monadic and applicative interfaces for composition,
+and supports incremental input through buffered and unbuffered interfaces.
+Both interfaces give the user total control over the blocking behavior of
+their application, with the unbuffered interface enabling zero-copy IO.
+Parsers are backtracking by default and support unbounded lookahead.")
