Poop, we didn't talk about this :(  All I managed to do was to get my
eclipse to eat my lpcusb directory where I was prototyping my USB data
blaster for testing the RT charactoristics :(

I need this for my openAHRMS thing.  I have a host test program to
test with.  (nothing fancy)

I don't think I'll use Eclipse any more.  The OCD scripts do a fine
job at loading and GDB works stand alone too.  Eclipse is an evil
trick played on developers that don't want to use the command line.

I wasn't using it until tonight when I was trying to recall what I did
with it 8 weeks ago to help the other guy (who really didn't need any
help as he got his working while I got it to rm -r my work)

grumble grumble.
