Bitwise Logical Operations

These routines treat numbers as collections of binary bits, and logical operations are performed on corresponding bits in the binary representation of the numbers. The << and >> operators can be used for shifting bits left or right respectively.

and_bits	perform logical AND on corresponding bits
or_bits	perform logical OR on corresponding bits
xor_bits	perform logical XOR on corresponding bits
not_bits	perform logical NOT on all bits
or_all	perform or_bits on all elements of a sequence
decode_flags	create a human readable string for a bit field.
