=head1 SYNOPSIS
See L<Mail::SPF::Record>.
=head1 DESCRIPTION
An object of class B<Mail::SPF::v1::Record> represents an B<SPFv1> (C<v=spf1>)
record.
=head2 Constructors
The following constructors are provided:
=over
=item B<new(%options)>: returns I<Mail::SPF::v1::Record>
Creates a new SPFv1 record object.
%options is a list of key/value pairs representing any of the following
options:
=over
=item B<text>
=item B<terms>
=item B<global_mods>
See L<Mail::SPF::Record/new>.
=item B<scopes>
See L<Mail::SPF::Record/new>. Since SPFv1 records always implicitly cover the
C<helo> and C<mfrom> scopes, this option must either be exactly B<['helo',
'mfrom']> (or B<['mfrom', 'helo']>) or be omitted.

if (defined(my $scopes = $self->{scopes})) {
@$scopes > 0
or throw Mail::SPF::EInvalidScope('No scopes for v=spf1 record');
@$scopes == 2 and
(
$scopes->[0] eq 'help' and $scopes->[1] eq 'mfrom' or
$scopes->[0] eq 'mfrom' and $scopes->[1] eq 'help'
)
or throw Mail::SPF::EInvalidScope(
"Invalid set of scopes " . join(', ', map("'$_'", @$scopes)) . " for v=spf1 record");
}
return $self;
}
=item B<new_from_string($text, %options)>: returns I<Mail::SPF::v1::Record>;
throws I<Mail::SPF::ENothingToParse>, I<Mail::SPF::EInvalidRecordVersion>,
I<Mail::SPF::ESyntaxError>
Creates a new SPFv1 record object by parsing the string and any options given.
=back
=head2 Class methods

=over
=item B<version_tag_pattern>: returns I<Regexp>
Returns a regular expression that matches a version tag of B<'v=spf1'>.
=item B<default_qualifier>
=item B<results_by_qualifier>
See L<Mail::SPF::Record/Class methods>.
=back
=head2 Instance methods
The following instance methods are provided:
=over
=item B<text>
=item B<scopes>
=item B<terms>
=item B<global_mods>
=item B<global_mod>
=item B<stringify>
=item B<eval>
See L<Mail::SPF::Record/Instance methods>.
=item B<version_tag>: returns I<string>
Returns B<'v=spf1'>.
