# Class Uq_engines.epsilon_engine

    class ['a] epsilon_engine : 'a engine_state -> Unixqueue.event_system -> ['a] engine

This engine transitions from its initial state ``Working 0` in one step to the passed constant state.

In previous versions of this library the class was called `const_engine`. However, this is not a constant thing. In particular, it is possible that this engine is aborted, so the passed state is not reached. To avoid programming errors because of the misnomer, this class has been renamed.
