-have not been redefined by \texttt{old-arrows}, because the corresponding characters $\leftharpoonup,\rightharpoonup,\leftharpoondown,\rightharpoondown$ have not been modified by the introduction of the new-style arrows.

 says that only the symbols $\mapsfrom$ and $\varmapsfrom$ will be defined by \texttt{stmaryrd}.

+\subsection{Additional arrow commands provided by \texttt{old-arrows}}
 
+The \texttt{old-arrows} package provides additional arrow commands that are listed in
+table~\ref{tab-comandi-nuovi}.
+\begin{table}[!htbp]
+\begin{symbols}{*2{cl}}
+ \X{\longhookrightarrow}          & \X{\longhookleftarrow}    \\
+ \X{\varlonghookrightarrow}$^a$   & \X{\varlonghookleftarrow}$^a$ \\
+ \X{\longleftharpoonup}           & \X{\longleftharpoondown}  \\
+ \X{\longrightharpoonup}          & \X{\longrightharpoondown} \\
+\end{symbols}
+\centerline{\footnotesize $^a$Available with the option \texttt{new}.}
+\caption{Arrow commands provided by \texttt{old-arrows}.}\label{tab-comandi-nuovi}
+\end{table}
+
+Finally, there are extensible ``mapsfrom'' arrows (table~\ref{tab-frecce-mt-smr}) that are available only if
+both \texttt{mathtools} and \texttt{stmaryrd} are loaded together with \texttt{old-arrows} (as they depend on
+commands defined by these two packages).

+\begin{symbols}{*2{cl}}
+ \W{\xmapsfrom}{ABCDEF} & \W{\varxmapsfrom}{ABCDEF}$^a$  \\
+\end{symbols}
