=head1 NAME

Solution::Tag::Unless - Unless: The Opposite of If

=head1 Description

Unless is the opposite of L<if|Solution::Tag::If>. The block is rendered
I<unless> the conditon is true.

=head1 Synopsis

    {% unless value == 5 %}
        Doesn't equal five!
    {% else %}
        Aww... it does equal five.
    {% endunless %}

=head1 Bugs

Since L<unless|Solution::Tag::Unless> is simply a subclass, see the list of
bugs for L<ifSolution::Tag::If>. They basically apply here too.

See L<Solution::Condition|Solution::Condition> for a list of supported
inequalities.
