Dist::Zilla::Plugin::AutoVersion - take care of numbering versions so you don't have to

=head1 VERSION

version 6.033

=head1 DESCRIPTION

This plugin automatically produces a version string, generally based on the
current time.  By default, it will be in the format: 1.yyDDDn

=head1 PERL VERSION

This module should work on any version of perl still receiving updates from
the Perl 5 Porters.  This means it should work on any version of perl
released in the last two to three years.  (That is, if the most recently
released version is v5.40, then this module should work on both v5.40 and
v5.38.)

Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to
lower the minimum required perl.

=head1 ATTRIBUTES

=head2 major

The C<major> attribute is just an integer that is meant to store the major
version number.  If no value is specified in configuration, it will default to
1.

This attribute's value can be referred to in the autoversion format template.

=head2 format

The format is a L<Text::Template> string that will be rendered to form the
version.  It is meant to access to one variable, C<$major>, and one subroutine,
C<cldr>, which will format the current time (in GMT) using CLDR patterns (for
which consult the L<DateTime> documentation).

The default value is:

  {{ $major }}.{{ cldr('yyDDD') }}
  {{ sprintf('%01u', ($ENV{N} || 0)) }}
  {{$ENV{DEV} ? (sprintf '_%03u', $ENV{DEV}) : ''}}
