-//	This bootloader creates a composite Serial device
-//
-//	The serial interface supports a STK500v1 protocol that is very similar to optiboot
-//
-//	The bootloader will timeout and start the firmware after a few hundred milliseconds
-//	if a usb connection is not detected.
-//	
-//	The tweakier code is to keep the bootloader below 2k (no interrupt table, for example)
