+ * \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 HWB mechanism of the USB AVRs; ground the HWB pin (see device
+ * datasheet) then momentarily ground /RESET to start the bootloader. This assumes the HWBE fuse is set and the 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 non-compatible with the cross-platform loader GUI. 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 BOOTRST fuse set, causing the bootloader
+ * to run automatically when the device is reset. In most cases, the BOOTRST
+ * fuse should 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.
