# ABSTRACT: Implements an item in a dependency hierarchy.

#pod =pod
#pod
#pod =head1 DESCRIPTION
#pod
#pod The Algorithm::Dependency::Item class implements a single item within the
#pod dependency hierarchy. It's quite simple, usually created from within a source,
#pod and not typically created directly. This is provided for those implementing
#pod their own source. ( See L for details ).

# Constructor

#pod =pod
#pod
#pod =head2 new $id, @depends
#pod
#pod The C constructor takes as its first argument the id ( name ) of the
#pod item, and any further arguments are assumed to be the ids of other items that
#pod this one depends on.
#pod
#pod Returns a new C on success, or C
#pod on error.
#pod
#pod =cut

	my $class = shift;
	my $id    = (defined $_[0] and ! ref $_[0] and $_[0] ne '') ? shift : return undef;
	bless { id => $id, depends => [ @_ ] }, $class;
}

#pod =head2 depends
#pod
#pod The C method returns, as a list, the names of the other items that
