In uAccess, the user can add drop-ins two ways. One is to drop resources
into a specified file. The other is to move files into a specified
folder. The former is hard, the latter easy.

What would be nice is if Apple provided a common mechanism, similar
to the Control Panel, that would provide a common interface for all
applications for adding, removing, and configuring drop-ins.

As for a "universal" calling convention, seems like a waste of effort,
since not every case can be fully covered. HOwever, it does seem that
a large number of "obvious" cases could be generalized. For instance,
uAccess has drop-ins that work on text selections in a text window.
This is the type of operation that could be generalized.
