+C<tag>

+Returns an identifier for the mod object.
+It is used to gather mods together when calling C<covers> on them.
+
+=item *
+
+C<covers $mod>
+
+Returns true if and only if the effects of the mod C<$mod> are already ensured by the current mod object, in which case no actual TikZ code will be emitted for C<$mod>.
+Both mod objects are guaranteed to have the same C<tag>.
+
+=item *
+
+C<declare $formatter>
+
+Returns an array reference of TikZ code lines required to declare this mod before using it, formatted by the L<LaTeX::TikZ::Formatter> object C<$formatter> ; or C<undef> if no declarations are needed for this mod.

+=item *
+
+C<apply $formatter>
+
+Returns the TikZ code that activates the current mod as a string formatted by the L<LaTeX::TikZ::Formatter> object C<$formatter>.
