version - Perl extension for Version Objects

=head1 SYNOPSIS

  # Parsing version strings (decimal or dotted-decimal)

  use version 0.77; # get latest bug-fixes and API
  $ver = version->parse($string)

  # Declaring a dotted-decimal $VERSION (keep on one line!)

  use version; our $VERSION = version->declare("v1.2.3"); # formal
  use version; our $VERSION = qv("v1.2.3");               # shorthand
  use version; our $VERSION = qv("v1.2_3");               # alpha

  # Declaring an old-style decimal $VERSION (use quotes!)

  our $VERSION = "1.0203";                                # recommended
  use version; our $VERSION = version->parse("1.0203");   # formal
  use version; our $VERSION = version->parse("1.02_03");  # alpha

  # Comparing mixed version styles (decimals, dotted-decimals, objects)

  if ( version->parse($v1) == version->parse($v2) ) {
    # do stuff
  }

  # Sorting mixed version styles

  @ordered = sort { version->parse($a) <=> version->parse($b) } @list;

=head1 DESCRIPTION

Version objects were added to Perl in 5.10.  This module implements version
objects for older version of Perl and provides the version object API for all
versions of Perl.  All previous releases before 0.74 are deprecated and should
not be used due to incompatible API changes.  Version 0.77 introduces the new
'parse' and 'declare' methods to standardize usage.  You are strongly urged to
set 0.77 as a minimum in your code, e.g.

  use version 0.77; # even for Perl v.5.10.0

=head1 TYPES OF VERSION OBJECTS

There are two different types of version objects, corresponding to the two
different styles of versions in use:

=over 2

=item Decimal Versions

The classic floating-point number $VERSION.  The advantage to this style is
that you don't need to do anything special, just type a number into your
source file.  Quoting is recommended, as it ensures that trailing zeroes
("1.50") are preserved in any warnings or other output.

=item Dotted Decimal Versions

The more modern form of version assignment, with 3 (or potentially more)
integers separated by decimal points (e.g. v1.2.3).  This is the form that
Perl itself has used since 5.6.0 was released.  The leading 'v' is now
strongly recommended for clarity, and will throw a warning in a future
release if omitted.  A leading 'v' character is required to pass the
L</is_strict()> test.

=head1 DECLARING VERSIONS

If you have a module that uses a decimal $VERSION (floating point), and you
do not intend to ever change that, this module is not for you.  There is
nothing that version.pm gains you over a simple $VERSION assignment:

  our $VERSION = "1.02";

Since Perl v5.10.0 includes the version.pm comparison logic anyways,
you don't need to do anything at all.

=head2 How to convert a module from decimal to dotted-decimal

If you have used a decimal $VERSION in the past and wish to switch to a
dotted-decimal $VERSION, then you need to make a one-time conversion to
the new format.

B<Important Note>: you must ensure that your new $VERSION is numerically
greater than your current decimal $VERSION; this is not always obvious. First,
convert your old decimal version (e.g. 1.02) to a normalized dotted-decimal
form:

  $ perl -Mversion -e 'print version->parse("1.02")->normal'
  v1.20.0

Then increment any of the dotted-decimal components (v1.20.1 or v1.21.0).

=head2 How to C<declare()> a dotted-decimal version

  use version; our $VERSION = version->declare("v1.2.3");

The C<declare()> method always creates dotted-decimal version objects.  When
used in a module, you B<must> put it on the same line as "use version" to
ensure that $VERSION is read correctly by PAUSE and installer tools.  You
should also add 'version' to the 'configure_requires' section of your
module metadata file.  See instructions in L<ExtUtils::MakeMaker> or
L<Module::Build> for details.

B<Important Note>: Even if you pass in what looks like a decimal number
("1.2"), a dotted-decimal will be created ("v1.200.0"). To avoid confusion
or unintentional err
