+/**
+ * Implementations perform the second phase of converting a logical model representing an assembly into a series of
+ * runtime or executable artifacts. Specifically, they are responsible for finalizing target-side proxy factories and
+ * bridging {@link org.apache.tuscany.core.wire.InvocationConfiguration}s held by source- and target-side proxy
+ * factories. <code>WireBuilder</code>s generally operate by target implementation type. In other words, for a wire
+ * from a Java source to a JavaScript target, the Javascript <code>WireBuilder</code> will complete the wire. This is
+ * necessary as a <code>WireBuilder</code> must set a {@link org.apache.tuscany.core.wire.TargetInvoker} that is
+ * responsible for dispatching to an implementation on the source side of the wire.
+ * <p>
+ * Runtimes are generally configured with a {@link org.apache.tuscany.core.builder.impl.DefaultWireBuilder} as a
+ * top-most wire builder, which delegates to other builders wired to it as part of a system configuration.
+ * <p>
+ * Wire builders may optimize the wire chains based on certain characteristics of th wire, such as source and
+ * target scopes.
