=head1 NAME
ExtUtils::XSpp::Node::Package - Node representing a Perl package
=head1 DESCRIPTION
An L<ExtUtils::XSpp::Node> subclass representing a Perl package and
thus acting as a container for methods (cf. sub-class
L<ExtUtils::XSpp::Node::Class>) or functions.
A literal C<ExtUtils::XSpp::Node::Package> would, for example,
be created from:
%package{Some::Perl::Namespace}
This would be compiled to a new XS line a la
MODULE=$WhateverCurrentModule PACKAGE=Some::Perl::Namespace
=head1 METHODS
=head2 new
Creates a new C<ExtUtils::XSpp::Node::Package>.
Named parameters: C<cpp_name> indicating the C++ class name
(if any), and C<perl_name> indicating the name of the Perl
package. If C<perl_name> is not specified but C<cpp_name> is,
C<perl_name> defaults to C<cpp_name>.
=cut
sub init {
my $this = shift;
my %args = @_;
$this->{CPP_NAME} = $args{cpp_name};
$this->{PERL_NAME} = $args{perl_name} || $args{cpp_name};
}
=head1 ACCESSORS
=head2 cpp_name
Returns the C++ name for the package (will be used for namespaces).
=head2 perl_name
Returns the Perl name for the package.
=head2 set_perl_name
Setter for the Perl package name.
