This module exercises Discoverer against Java's ServiceLoader across real module boundaries. It is not intended to be used as a dependency.
Its module-info.java provides sample implementations of org.scijava.ops.spi.Op and org.scijava.ops.spi.OpCollection, and its tests check that a Discoverer built with Discoverer.usingProviders(c -> ServiceLoader.load(c).stream()) finds them.
Note that ServiceLoader can only discover implementations of interfaces that the calling module declares it uses. This module therefore declares:
uses org.scijava.ops.spi.Op;
uses org.scijava.ops.spi.OpCollection;
