Perl-Bit-Vector 6.4 - A module for high-performance Perl manipulation of bit vectors.

Bit::Vector is an efficient C library which allows you to handle bit vectors, sets (of integers), "big integer arithmetic" and boolean matrices, all of arbitrary sizes.

The library is efficient (in terms of algorithmical complexity) and therefore fast (in terms of execution speed) for instance through the widespread use of divide-and-conquer algorithms.
