Re: gEDA-user: GND and Vcc pin on IC 74245

[Stephen Meier]

If one assumes that gnd and vcc are well defined and well known as in 
the 74xx family removing them from the schematic makes the drawing simpler.

However this isn't always the case.

Could someone explain why logic ICs must not have Vcc and GND pins?
I have never seen a good reason for this. What is wrong with having 
Vcc and GND pins - like any other pin?
