# Haar

Haar is a command line tool to help you write diagrams with plant uml and then surface and expose those diagrams to the people on your team.

> In meteorology, haar is a cold sea fog. It usually occurs on the east coast of England or Scotland between April and September, when warm air passes over the cold North Sea.
