-/** The `Application` trait can be used to quickly turn objects
- *  into executable programs, but is ''not recommended''.
- *  Here is an example:
- *  {{{
- *  object Main extends Application {
- *    Console.println("Hello World!")
- *  }
- *  }}}
- *  Here, object `Main` inherits the `main` method of `Application`.
- *  The body of the `Main` object defines the main program. This technique
- *  does not work if the main program depends on command-line arguments
- *  (which are not accessible with the technique presented here).
- *
- *  It is possible to time the execution of objects that inherit from class
- *  `Application` by setting the global `scala.time`
- *  property. Here is an example for benchmarking object `Main`:
- *  {{{
- *  java -Dscala.time Main
- *  }}}
- *  In practice the `Application` trait has a number of serious pitfalls:
- *
- *  - Threaded code that references the object will block until static
- *    initialization is complete.  However, because the entire execution
- *    of an `object` extending `Application` takes place during
- *    static initialization, concurrent code will ''always'' deadlock if
- *    it must synchronize with the enclosing object.
- *  - As described above, there is no way to obtain the
- *    command-line arguments because all code in body of an `object`
- *    extending `Application` is run as part of the static initialization
- *    which occurs before `Application`'s `main` method
- *    even begins execution.
- *  - Static initializers are run only once during program execution, and
- *    JVM authors usually assume their execution to be relatively short.
- *    Therefore, certain JVM configurations may become confused, or simply
- *    fail to optimize or JIT the code in the body of an `object` extending
- *    `Application`.  This can lead to a significant performance degradation.
- *
- *  It is recommended to use the [[scala.App]] trait instead.
- *  {{{
- *  object Main {
- *    def main(args: Array[String]) {
- *      //..
- *    }
- *  }
- *  }}}
