<description>&lt;b&gt;Supply Symbols&lt;/b&gt;&lt;p&gt;
GND, VCC, 0V, +5V, -5V, etc.&lt;p&gt;
Please keep in mind, that these devices are necessary for the
automatic wiring of the supply signals.&lt;p&gt;
The pin name defined in the symbol is identical to the net which is to be wired automatically.&lt;p&gt;
In this library the device names are the same as the pin names of the symbols, therefore the correct signal names appear next to the supply symbols in the schematic.&lt;p&gt;
