' Please read the Readme.rtf file which should have been
' included in the zip file.

' note on C bitwise operators here and VB equivalents
' & = Bitwise AND = And
' | = Bitwise Inclusive OR = Or
' ^ = Bitwise Exclusive OR = Xor
' << = Left Shift = {No equivalent}
' >> = Right Shift = {No equivalent}
' ~ = One's complement = Not
'
' I am reliably informed that in VB 7 new operators will be
' introduced for the above operations:
' & = BitAnd
' | = BitOr
' ^ = BitXor
'
' etc.
' Please bear this in mind if compiling using VB7 (or it won't work)!
' Additionally, if those lovely people at Microsoft ever
' allow VB to do bit shifting, please change all the calls
' to the LshL and LshR functions.  Sigh.
