  *  This bootloader enumerates to the host as a HID Class device, allowing for device FLASH programming through
  *  the supplied command line software, which is a modified version of Paul's TeensyHID Command Line loader code
  *  from PJRC (used with permission). This bootloader is deliberatley non-compatible with the properietary PJRC
  *  HalfKay bootloader GUI; only the command line interface software accompanying this bootloader will work with it.

  *  Out of the box this bootloader builds for the AT90USB1287 with an 8KB bootloader section size, and will fit
  *  into 2KB of bootloader space for the Series 2 USB AVRs (ATMEGAxxU2, AT90USBxx2) or 4KB of bootloader space for
  *  all other models. If you wish to alter this size and/or change the AVR model, you will need to edit the MCU,
  *  FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile.
