# The ordering is alphabetical by page name, as it appears in the SCSI spec.

# 'i' is a byte-sized integral types, followed by a field width of 
#  1 through 4 (1 to 4 bytes).
#
# 'b' is a bit-sized integral type
# 't' is a bitfield type- followed by a bit field width
#
# 'c' values are character arrays
# 'z' values are null-padded strings
#
#
# '*' suppresses assignment (for 'seeking').
# Bitfields are MSB to LSB.
