-		# the function is the key.  Each node switches on a range of
-		# bits from the opcode.  M bits are extracted from the opcde
-		# and are used as an index to select one of the N, where
-		# N = 2^M, children.
-		#
-		# The tree is stored as a flat array.  The first value is the
-		# number of bits, M, used by the node.  For inner nodes, the
-		# following 2^M values are indexes into the array for the
-		# child nodes.  For leaf nodes, the followign 2^M values are
-		# indexes into the second data structure.
-		#
-		# If an inner node's child index is 0, the child is an empty
-		# leaf node.  That is, none of the opcodes selectable from
-		# that child exist.  Since most of the possible opcode space
-		# is unused, this allows compact data storage.
-		#
-		# The second data structure is an array of pairs of function
-		# pointers.  Each function contains a pointer to a protocol
-		# decode function and a pointer to a byte-swapped protocol
-		# decode function.  Elements in this array are selected by the
-		# leaf nodes of the first data structure.
-		#
-		# As the tree is traversed, an accumulator is kept.  This
-		# accumulator counts the bits of the opcode consumed by the
-		# traversal.  When accumulator + M = B, where B is the
-		# maximum number of bits in an opcode, the traversal has
-		# reached a leaf node.  The traversal starts with the most
-		# significant bits and works down to the least significant
-		# bits.
-		#
-		# Creation of the tree is the most complicated part.  At
-		# each node the elements are divided into groups of 2^M
-		# elements.  The value of M selected is the smallest possible
-		# value where all of the groups are either empty or full, or
-		# the groups are a preset minimum size.  If all the children
-		# of a node are non-empty leaf nodes, the children are merged
