      2 JTAGONIZER * Yet Another JTAG Tool
      3 
      4 This is a set of tools for talking to hardware over JTAG, currently
      5 supporting the popular FTDI 2232H MPSSE devices for transport.  It
      6 does have a "driver abstraction" with the intent to support other
      7 transports someday, but only the mpsse driver exists right now.
