Hello!
The recent discussion on geda-user triggered me to propose more universal way 
of handling opwer pins.
This should allow to introduce eagle style IC power supply symbols in gEDA 
wihout loss of compatibility with existing system.

1) All net= atributes inside symbols should be replaced with another one 
(named "power" or something like). The new attribute can have the same syntax 
for easy transition.

2) An utilty in gschem (or external tool) should look into the symbol and:

a) create net= attributes based on internal power= attributes to make gaf 
style power nets. This net= attributes are external so they can be easily 
edited if necessary.

or:

b1) insert a predefined power symbol for parts with standard power pinning 
(7/14, 8/16 or so)

or

b2) insert an embedded symbol specially crafted if no standard power symbol is 
found (optional?)

The "b" way gives eagle style power distribution.

The solution should be forward and almost backward compatible with current 
geda releases.
