The directory structure diagram got messed up because the whitespace
was removed. Here it is again, substituting periods for spaces:

src---|Jamroot
......|
......|---lib1---|Jamfile
......|..........|World.h
......|..........|World.cxx
......|..........|
......|..........|---lib2---|Jamfile
......|.....................|Hello.h
......|.....................|Hello.cxx
......|
......|---app---|Jamfile
................|helloWorld.cxx
