Footprints for pcb , the interactive pcb layout editor (http://pcb.sourceforge.net) I Added a directory structure to reflect the status of the footprint. "01_draft" The basic idea is to start with a footprint in this directory. "02_unstable" This is a directory for newly born footprints which have not been scrutenised for flaws or errors whatsoever. "03_stable" This is a directory for footprints used in pcb design (files). "04_released" This is a directory for footprints used in an actual pcb (copper).
