I am pleased to announce version 5.6 of the "Bit::Vector" module:
The package is available for download either from my web site at
http://www.engelschall.com/u/sb/download/
or from any CPAN (= "Comprehensive Perl Archive Network") mirror server:
(allow a few days for propagation if necessary)
http://www.perl.com/CPAN/authors/id/STBEY/
The package consists of a C library (designed for maximum efficiency)
which is the core of a Perl module (designed for maximum ease of use).
The C library is specifically designed so that it can be used stand-alone,
without Perl.
What does it do:
----------------
This module is useful for a large range of different tasks:
- For example for implementing sets and performing set operations
(like union, difference, intersection, complement, check for subset
relationship etc.),
- as a basis for many efficient algorithms, for instance the
"Sieve of Erathostenes" (for calculating prime numbers),
(The complexities of the methods in this module are usually either
O(1) or O(n/b), where "b" is the number of bits in a machine word
on your system.)
- for shift registers of arbitrary length (for example for cyclic
redundancy checksums),
- to calculate "look-ahead", "first" and "follow" character sets
for parsers and compiler-compilers,
- for graph algorithms,
- for efficient storage and retrieval of status information,
- for performing text synthesis ruled by boolean expressions,
- for "big integer" arithmetic with arbitrarily large integers,
- for manipulations of chunks of bits of arbitrary size,
- for bitwise processing of audio CD wave files,
- to convert formats of data files,
and more.
What's new in version 5.6:
--------------------------
The leading zeros in the output of "to_Hex()" have been suppressed.
BEWARE:
It is unlikely, but this may actually break existing applications!
Additionally, a warning produced by some compilers on line 2067 of
"BitVector.c" has been fixed.

I would in fact be glad to receive any kind of feedback from you!
I hope you will find this module beneficial.
