=head1 SYNOPSIS

    use Net::DNS;
    $rr = new Net::DNS::RR('name SPF spfdata ...');

    $rr = new Net::DNS::RR( name    => 'name',
			    type    => 'SPF',
			    spfdata => 'single text string'
			    );

    $rr = new Net::DNS::RR( name    => 'name',
			    type    => 'SPF',
			    spfdata => [ 'multiple', 'strings', ... ]
			    );

=head1 DESCRIPTION

Class for DNS Sender Policy Framework (SPF) resource records.

SPF records inherit most of the properties of the Net::DNS::RR::TXT
class.

=head1 METHODS

The available methods are those inherited from the base class augmented
by the type-specific methods defined in this package.

Use of undocumented package features or direct access to internal data
structures is discouraged and could result in program termination or
other unpredictable behaviour.


=head2 spfdata

=head2 txtdata

    $string = $rr->spfdata;
    @list   = $rr->spfdata;

    $rr->spfdata( @list );

When invoked in scalar context, spfdata() returns the policy text as
a single string, with text elements concatenated without intervening
spaces.

In a list context, spfdata() returns a list of the text elements.
