Notes to self:

1. don't do teardrops (at least, not using the Eagle ULP.)  They become very messy when you move any components.  Maybe "snowmen" instead?
2. Part renumbering?  How ?  By schematic placement, board placement, component value, logical use?
3. The script for copying/resizing silkscreen elements needs an option to do a single component, or list of components, so that added components can be added to the customized silkscreen more easily.  Maybe even a component attribute to indicate whether the silkscreen has been generated yet?
