I'm not sure this is correct btw. The -e does an erase, but not of usersig. 
That's supposed to be the beauty of usersig, is that an erase/reprogram doesn't 
clobber your usersig settings. I tried with -e, and it never seemed to erase my 
usersig, but it did clobber the program that was in flash, so that i had to 
reprogram it.
