It is equivalent to using Template:interlinear with the parameters |italics1=no |italics2=yes and |glossing3=yes. It accepts all of that template's parameters (see its documentation for advanced usage). Additionally, the transliteration scheme can be specified with the |transl= parameter (similarly to Template:Transl).
