> The mapping file includes manufacturer, part no, pin mapping and footprint information. gschem doesn't store 'footprint', but 'component' attributes for parts, and pins have logical names which are used in the mapping file, instead of numbers. That makes it possible to have different boards (e.g. a 2-layer THT and and a 4-layer SMD board) made from the same schematic, or to make 10 different boards which just differ in the relays (and their footprints) used, etc.

That kind of mapping would be handy. However, I note that gEDA can already do this kind of thing with project-specific "heavy" symbols. Change the symbol library, change footprints, part numbers, etc. I do this routinely, since flight parts are often different from prototype parts.
