 ANNOUNCE: Bit::Vector 5.3

I am pleased to announce version 5.3 of the "Bit::Vector" module:

The package is available for download either from my web site at

                  http://www.*-*-*.com/

or from any CPAN (= "Comprehensive Perl Archive Network") mirror server:
(allow a few days for propagation if necessary)

                  http://www.*-*-*.com/

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 5.3:
--------------------------

The method "Norm()" has been further improved to become still a bit more
efficient.

The upgrade utility "upgrade_BV52" (a shell script) was ported to Perl
(now named "upgrade_BV53.pl"), making it faster, more flexible and easier
to read and maintain and -- last but not least -- executable under
Windows NT/95 as well.

Moreover, a similar tool for upgrading from "Set::IntegerFast" version 3.x
to "Bit::Vector" version 4.2 (called "upgrade_BV42.pl") was added.

Support for Windows NT/95 was also improved by adding the extension ".txt"
to all text files (where possible) in order to allow opening them with a
double-click.

Finally, the document "CHANGES.txt" was completely rewritten because
it had become a terrible mess.
