    There is a finite list of _manufactured_ crystals. This file aims
    to document all of the known speeds that crystals were available in.
    Feel free to add to the list if you find another speed crystal on
    a PCB, but please DON'T GUESS!

    Remember that some very high frequencies (typically above 100MHz) are
    generated by a frequency multiplying IC from a lower frequency
    crystal.

    This is intended as a reference of existing parts to prevent incorrect
    clock speed measurements with digital frequency counters being used
    in drivers. When measuring clocks, remember that most parts have a
    tolerance so be sure to reference existing parts only and not just
    accept direct readings as 100% true.

    (Thanks to Guru for starting this documentation.)
