Once again, this assumes the presence of a "design", which is the same concept 
a "project".  Which is something that is not

This approach works well for parts where the pinout is always the same 
(resistors, capacitors, many diodes & transistors) but fails spectacularly 
for more complex parts.  However, it's worth considering.

Note that you could do something quite similar _now_ using a couple of Scheme 
functions and the component-library-funcs rc file procedure (as long as 
you're running git unstable).
