/**
 * A KiCad HTTP library provides both symbol and footprint metadata, so there are "shim" plugins
 * on both the symbol and footprint side of things that expose the database contents to the
 * schematic and board editors.  The architecture of these is slightly different from the other
 * plugins because the backing file is just a configuration file rather than something that
 * contains symbol or footprint data.
