description """
General `logic function' component.  Can perform `and', `or',
`nand', `nor' and `xor' of up to 16 inputs.
.LP
Determine the proper value for `personality'
by adding the inputs and outputs then convert to hex:
.IP \\(bu 4
The number of input pins, usually from 2 to 16
.IP \\(bu
256 (0x100)  if the `and' output is desired
.IP \\(bu
512 (0x200)  if the `or' output is desired
.IP \\(bu
1024 (0x400)  if the `xor' (exclusive or) output is desired
.IP \\(bu
2048 (0x800)  if the `nand' output is desired
.IP \\(bu
4096 (0x1000)  if the `nor' output is desired
.LP
Outputs can be combined, for example 2 + 256 + 1024 = 1282 converted to hex
would be 0x502 and would have two inputs and have both `xor' and `and' outputs.
