        !             3: .SH NAME
        !             4: pins \- look up pin names
        !             5: .SH SYNOPSIS
        !             6: .B pins
        !             7: .I pattern ...
        !             8: .SH DESCRIPTION
        !             9: .I pins
        !            10: prints the description of
        !            11: the chip type
        !            12: .I pattern
        !            13: from the file
        !            14: .BR /usr/lib/cda/lib/pins .
        !            15: .I pattern 
        !            16: is in a form suitable for
        !            17: .IR grep (I).
        !            18: If the name matched is a synonym for another part,
        !            19: both type names will be printed.
        !            20: The pin names and pin numbers are used by the
        !            21: circuit macro expander

        !            25: Naming Conventions
        !            26: .PP
        !            27: A set of pin naming conventions is used,
        !            28: based on the traditional naming found 
        !            29: in, for example, the Texas Instruments TTL Data Book.
        !            30: Function inputs and outputs are usually
        !            31: given as a single capital letter.
        !            32: Special inputs and outputs are given a 
        !            33: short mnemonic name, such as \fBCLR\fP for clear.
        !            34: Lowercase letters are used where a subscript might
        !            35: normally be used.
        !            36: Where multiple gates exist within a single package,
        !            37: they are distinguished by appending a zero based numeric index.
        !            38: Pins which are active when low are indicated by
        !            39: adding a minus sign as the last character of the name.
        !            40: .LP
        !            41: General inputs are labeled with a single letter starting
        !            42: with the letter 
        !            43: .BR A .
        !            44: Functions with single inputs use the letter 
        !            45: .B D 
        !            46: with indices,
        !            47: as well as memories and flip-flops.
        !            48: When the outputs of logic elements are
        !            49: not synchronous
        !            50: with respect to another input
        !            51: they are named
        !            52: .BR Y .
        !            53: Synchronous outputs, such as with flip-flops are called 
        !            54: .BR Q .
        !            55: Clock lines are called 
        !            56: .BR CK ,
        !            57: clear lines are called 
        !            58: .BR CLR ,
        !            59: preset lines are called 
        !            60: .BR PR .
        !            61: Select lines for multiplexors and data selectors
        !            62: are called 
        !            63: .BR S .
        !            64: The letter 
        !            65: .B G 
        !            66: is used for 
        !            67: enable, chip enable, chip select, and output enable.
        !            68: The use of 
        !            69: .B OE 
        !            70: for output enable is used for 
        !            71: tri-state devices where there is a separate enabling
        !            72: of the chip and its outputs (such as 74S373).
        !            73: Memories use the letter 
        !            74: .B A
        !            75: for address lines,
        !            76: .B WE 
        !            77: for write enable
        !            78: and 
        !            79: .B Y 
        !            80: for outputs.
