* <p>Customizers run after all configurations have been applied to

* then perform additional work to further customize the configuration.</p>
*
* <p>The execution of customizers is currently divided into two phases,
* {@link org.wildfly.swarm.spi.runtime.annotations.Pre} and {@link org.wildfly.swarm.spi.runtime.annotations.Post}.
* All {@code Pre} customizers are executed in arbitrary order, followed immediately
* by all {@code Post} customizers, also in arbitrary order.</p>
*
* <p>Usually a {@code Customizer} may {@link javax.inject.Inject} various other
* components, such as various {@link Fraction} or {@link SocketBindingGroup} instances.</p>
*
* @apiNote Used by {@code Fraction} authors.
