Its not the application that I'm concerned about - an application is
typically a single/few file(s) and editing them to suit things is
certainly not an issue. But editing 100 files inside a package each
time the parent changes is nuts.
There is another way to get around this by manipulating __path__
inside a sub package. But this leads to the same module being
imported several times. This is what I use currently and its evil. :(
