+\subsection*{User specified junction and alignment styles (tricky)}
+%
+%
+When in radial mode, \texttt{drv} composes derivation trees by stating
+\emph{angular} constraints rather than horizontal ones. To this end, three
+distinguished angles are associated with each component \param{cpn}, namely
+\texttt{\param{cpn}.lng}, \texttt{\param{cpn}.cng} and \texttt{\param{cpn}.rng}
+that refer to the relative angles of \texttt{\param{cpn}.l},
+\texttt{\param{cpn}.c} and \texttt{\param{cpn}.r} respectively. (Radial
+constraints are essentially the same as vertical ones; however, each component
+comes also with a radius \texttt{\param{cpn}.rad} and an origin point
+\texttt{\param{cpn}.org}.)
+
+You can prevent \texttt{drv} from stating angular constraints about
+premises junction or judgments alignment by using the junction
+style~\texttt{3} or the alignment style~\texttt{u} of the \texttt{NFR} and
+\texttt{NFR\_opt} macros (see~\S~\ref{sec-NFR-DCL-MVD},~\ref{sec-labels}).
+Then again, you have to state your own constraints. As an example, compare the
+code below with the one for figure~510 on page~\pageref{fig-510}.
