=over 4

=item C<my $def = Automake::new ($comment, $location, $owner)>

Create a new Makefile-item definition.

C<$comment> is any comment preceding the definition.  (Because
Automake reorders items in the output, it also tries to carry comments
around.)

C<$location> is the place where the definition occurred, it should be
an instance of L<Automake::Location>.

C<$owner> specifies who owns the rule.

documentation of C<new>'s arguments for a description of these.
