+/**
+ * == Commonly Used Patterns With Akka ==
+ *
+ * This package is used as a collection point for usage patterns which involve
+ * actors, futures, etc. but are loosely enough coupled to (multiple of) them
+ * to present them separately from the core implementation. Currently supported
+ * are:
+ *
+ * <ul>
+ * <li><b>ask:</b> create a temporary one-off actor for receiving a reply to a
+ * message and complete a [[akka.dispatch.Future]] with it; returns said
+ * Future.</li>
+ * <li><b>pipeTo:</b> feed eventually computed value of a future to an actor as
+ * a message.</li>
+ * </ul>
+ *
+ * In Scala the recommended usage is to import the pattern from the package
+ * object:
+ * {{{
+ * import akka.pattern.ask
+ *
+ * ask(actor, message) // use it directly
+ * actor ask message   // use it by implicit conversion
+ * }}}
+ *
+ * For Java the patterns are available as static methods of the [[akka.pattern.Patterns]]
+ * class:
+ * {{{
+ * import static akka.pattern.Patterns.ask;
+ *
+ * ask(actor, message);
+ * }}}
