jjg@1416 31 * The interface for a javac plug-in.
jjg@1416 32 *
jjg@1416 33 * <p>The javac plug-in mechanism allows a user to specify one or more plug-ins
jjg@1416 34 * on the javac command line, to be started soon after the compilation
jjg@1416 35 * has begun. Plug-ins are identified by a user-friendly name. Each plug-in that
jjg@1416 36 * is started will be passed an array of strings, which may be used to
jjg@1416 37 * provide the plug-in with values for any desired options or other arguments.
jjg@1416 38 *
jjg@1416 39 * <p>Plug-ins are located via a {@link ServiceLoader},
jjg@1416 40 * using the same class path as annotation processors (i.e.
jjg@1416 41 * {@link StandardLocation#PROCESSOR_PATH PROCESSOR_PATH} or
jjg@1416 42 * {@code -processorpath}).
jjg@1416 43 *
jjg@1416 44 * <p>It is expected that a typical plug-in will simply register a
jjg@1416 45 * {@link TaskListener} to be informed of events during the execution
jjg@1416 46 * of the compilation, and that the rest of the work will be done
jjg@1416 47 * by the task listener.
