## NAME
    [CPAN::Meta::Feature](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta%3A%3AFeature/markdown) - an optional feature provided by a CPAN distribution

## VERSION
    version 2.150010

## DESCRIPTION
    A [CPAN::Meta::Feature](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta%3A%3AFeature/markdown) object describes an optional feature offered by a CPAN distribution and
    specified in the distribution's META.json (or META.yml) file.

    For the most part, this class will only be used when operating on the result of the "feature" or
    "features" methods on a [CPAN::Meta](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta/markdown) object.

## METHODS
  new
      my $feature = [CPAN::Meta::Feature](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta%3A%3AFeature/markdown)->new( $identifier => \%spec );

    This returns a new Feature object. The %spec argument to the constructor should be the same as
    the value of the "optional_feature" entry in the distmeta. It must contain entries for
    "description" and "prereqs".

  identifier
    This method returns the feature's identifier.

  description
    This method returns the feature's long description.

  prereqs
    This method returns the feature's prerequisites as a [CPAN::Meta::Prereqs](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta%3A%3APrereqs/markdown) object.
