-
-This provides a simple boolean attribute, which supports most of the
-basic math operations.
-
-=head1 METHODS

-
-=head1 PROVIDED METHODS
-
-It is important to note that all those methods do in place
-modification of the value stored in the attribute.
-
-=over 4
-
-=item I<set>
-
-Sets the value to C<1>.
-
-=item I<unset>
-
-Set the value to C<0>.
-
-=item I<toggle>
-
-Toggle the value. If it's true, set to false, and vice versa.
-
-=item I<not>
-
-Equivalent of 'not C<$value>'.

-
-=head1 BUGS
-
-All complex software has bugs lurking in it, and this module is no
