# You can use this to override default values such as

# 'out.dir' for the location of your output folder.
# You can also use it define how the release builds are signed by declaring
# the following properties:

# The password will be asked during the build when you use the 'release' target.

// 2, all methods resolve in C++. For item 3, our CEO, getTitle calls
// getPosition which resolves in Java. The call to getPosition is
// slightly different, however, because of the overridden getPosition() call, since
// now the object reference has been "laundered" by passing through
// EmployeeList as an Employee*. Previously, Java resolved the call
// immediately in CEO, but now Java thinks the object is an instance of
// class Employee. So the call passes through the
// Employee proxy class and on to the C wrappers and C++ director,
// eventually ending up back at the Java CEO implementation of getPosition().
// The call to getTitle() for item 3 runs the C++ Employee::getTitle()
// method, which in turn calls getPosition(). This virtual method call
// passes down through the C++ director class to the Java implementation
// in CEO. All this routing takes place transparently.
