[Robotgroup] PIC bootloader from Microchip

[Robo Al]

Which part you want to try? I just use it to compile, I actually
do all my coding in emacs :-)

If you are talking about using a bootloader I bought the UBW which
came with one installed. If you need one programmed into a chip that
you have I can bring a programmer and do that for you.
