As a simple gEDA/PCB example I did a remix of Drawdio using the ladyada schematic. The documentation file contains plots of the schematic and pcb layouts, embedded datasheets of all components used, BOM and component lists. Line items in the BOM and component list hyperlink to the appropriate datasheet. The tarball contains the schematic and PCB source files.
John, the maker of this remix is hardcore on the open source hardware tool front “You can’t create open hardware with closed EDA tools” — how many folks here use gEDA for PCB’ing?
