This is the first release of Microparsec, a performant Nim parsing library built for humans. This release mostly implements features from Attoparsec. This supports Nim 1.2.6+ and can be installed using Nimble:

$ nimble install microparsec

The basic design consists of wrapping a stream (from the standard streams library) to hold a state as we parse. All parsers then use this wrapped interface, so that the state is always in sync.

The error messages are heavily inspired by Megaparsec.
