+ *  \section SSec_Description Project Description:
+ *
+ *  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 deliberately non-compatible with the proprietary 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.
+ *
+ *  \warning <b>THIS BOOTLOADER IS NOT SECURE.</b> Malicious entities can recover written data, even if the device
+ *           lockbits are set.
+ *
+ *  \section Sec_Running Running the Bootloader
+ *
+ *  This bootloader is designed to be started via the \c HWB mechanism of the USB AVRs; ground the \c HWB pin (see device
+ *  datasheet) then momentarily ground \c /RESET to start the bootloader. This assumes the \c HWBE fuse is set and the
+ *  \c BOOTRST fuse is cleared.
+ *
+ *  \section Sec_Installation Driver Installation
+ *
+ *  This bootloader uses the HID class driver inbuilt into all modern operating systems, thus no additional drivers
+ *  need to be supplied for correct operation.
+ *
+ *  \section Sec_HostApp Host Controller Application
+ *
+ *  Due to licensing issues, the supplied bootloader is compatible with the HalfKay bootloader protocol designed
+ *  by PJRC, but is <b>not compatible with the cross-platform loader GUI</b>. A modified version of the open source
+ *  cross-platform TeensyLoader application is supplied, which can be compiled under most operating systems. The
+ *  command-line loader application should remain compatible with genuine Teensy boards in addition to boards using
+ *  this custom bootloader.
+ *
+ *  Once compiled, programs can be loaded into the AVR's FLASH memory through the following example command:
+ *  \code
+ *  hid_bootloader_cli -mmcu=at90usb1287 Mouse.hex
+ *  \endcode
+ *
+ *  \section Sec_KnownIssues Known Issues:
+ *
+ *  \par After loading an application, it is not run automatically on startup.
+ *  Some USB AVR boards ship with the \c BOOTRST fuse set, causing the bootloader
+ *  to run automatically when the device is reset. This booloader requires the
+ *  \c BOOTRST be disabled and the HWBE fuse used instead to run the bootloader
+ *  when needed.
+ *
+ *  \section SSec_Options Project Options
+ *
+ *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
