This project began life as a proof (bet) that a base caller could be written in a low level language in
under 8 hours. Some of the poor and just plain odd design decisions, along with the lack of
documentation, are a result of its inception. In keeping with ONT's fish naming policy, the project was
originally called Crappie.
Scrappie's purpose is to demonstrate the next generation of base calling and, as such, may change
drastically between releases and breaks backwards compatibility. Newer versions may drop support of
current features or change their behaviour.
