what I want to accomplish.
All tasks using a scanDir method to find the source files that are
newer than there targets should get a similar treatment as <copy>.
The major benefit is not to have the functionality in one place but
the added flexibility you get, when you allow the user to specify a
custom FileNameMapper to a task (not there yet).
Nothing (especially not the names) is carved into stone of course.
