libdata-bitmask-perl - 1.00-1 main

Data::BitMask is a Perl module to create bitmask manipulator objects
that can be used to create bitmask values based on a list of
constants, as well as to break apart masks using those constants. The
advantages are that you don't have to pollute namespaces to use
constants, you can ensure that only appropriate constants are used for
specific masks, you can easily break apart and explain masks, and in
general it is much easier for the user to interact with masks.
