#%C [options]
#
#This script mounts a thumb drive as /dos/usb.
#
#Valid DOS partition types are 1, 4, 5, 6, 11, 12, 14, 15
#Partitions are searched for based on type in that order.
#If a drive has multiple partitions, only the first
#partition will be mounted.
#
#If the drive has no partitions the script will attempt to
#mount the raw device as a DOS drive...again as /dos/usb
#
#If the /bin/io-usb and /bin/Fatfsys processes are not
#already running, it will run them for you.
#
#
#Options:
# -u    : umount thumb drive and clean up the drivers
# -v    : verbose
