+  \begin{itemize}
+    \item Valgrind can also act as a GDB server which can receive and process
+    commands. One can interact with valgrind gdb server either with a gdb
+    client, or directly with \code{vgdb} program (provided with valgrind).
+    \code{vgdb} can be used in different ways:
+    \begin{itemize}
+      \item As a standalone CLI program to send "monitor" commands to valgrind
+      \item As a relay between a gdb client and an existing valgrind session
+      \item As a server to drive multiple valgrind sessions from a remote gdb
+      client
+    \end{itemize}
+    \item See \manpage{vgdb}{1} for available modes, commands and options
+    \end{itemize}
