          <p style="margin-left: 20px;">ANTLR used a public domain notice through version 2.7 and then switched to a BSD license for version 3.0 and later. Their original notice did not include the third paragraph with the fallback license listed here; see ANTLR-PD for the version without this third paragraph.</p>
