=head1 NAME
Pinto::PackageSpec - Specifies a package by name and version
=head1 VERSION
version 0.097
=head1 METHODS
=head2 is_core
=head2 is_core(in => $version)
Returns true if this package is satisfied by the perl core as-of a particular
version. If the version is not specified, it defaults to whatever version
you are using now.
=head2 is_perl()
Returns true if this package is perl itself.
=head2 to_string()
Serializes this PackageSpec to its string form. This method is called
whenever the PackageSpec is evaluated in string context.
