NAME
       CPAN::Meta::Prereqs - a set of distribution prerequisites by phase and
       type
VERSION
       version 2.120921
DESCRIPTION
       A CPAN::Meta::Prereqs object represents the prerequisites for a CPAN
       distribution or one of its optional features.  Each set of prereqs is
       organized by phase and type, as described in CPAN::Meta::Prereqs.
METHODS
   new
         my $prereq = CPAN::Meta::Prereqs->new( \%prereq_spec );
       This method returns a new set of Prereqs.  The input should look like
       the contents of the "prereqs" field described in CPAN::Meta::Spec,
       meaning something more or less like this:
         my $prereq = CPAN::Meta::Prereqs->new({
           runtime => {
             requires => {
               'Some::Module' => '1.234',
               ...,
             },
             ...,
           },
           ...,
         });
       You can also construct an empty set of prereqs with:
         my $prereqs = CPAN::Meta::Prereqs->new;
       This empty set of prereqs is useful for accumulating new prereqs before
       finally dumping the whole set into a structure or string.
   requirements_for
         my $requirements = $prereqs->requirements_for( $phase, $type );
       This method returns a CPAN::Meta::Requirements object for the given
       phase/type combination.  If no prerequisites are registered for that
       combination, a new CPAN::Meta::Requirements object will be returned,
       and it may be added to as needed.
       If $phase or $type are undefined or otherwise invalid, an exception
       will be raised.
   with_merged_prereqs
         my $new_prereqs = $prereqs->with_merged_prereqs( $other_prereqs );
         my $new_prereqs = $prereqs->with_merged_prereqs( \@other_prereqs );
       This method returns a new CPAN::Meta::Prereqs objects in which all the
       other prerequisites given are merged into the current set.  This is
       primarily provided for combining a distribution's core prereqs with the
       prereqs of one of its optional features.
       The new prereqs object has no ties to the originals, and altering it
       further will not alter them.
   as_string_hash
       This method returns a hashref containing structures suitable for
       dumping into a distmeta data structure.  It is made up of hashes and
       strings, only; there will be no Prereqs, CPAN::Meta::Requirements, or
       "version" objects inside it.
   is_finalized
       This method returns true if the set of prereqs has been marked
       "finalized," and cannot be altered.
   finalize
       Calling "finalize" on a Prereqs object will close it for further
       modification.  Attempting to make any changes that would actually alter
       the prereqs will result in an exception being thrown.
   clone
         my $cloned_prereqs = $prereqs->clone;
       This method returns a Prereqs object that is identical to the original
       object, but can be altered without affecting the original object.
       Finalization does not survive cloning, meaning that you may clone a
       finalized set of prereqs and then modify the clone.
