+@subsection msg_ex_ns3 NS3 as a SimGrid Network Model
+
+This example demonstrates how to use the bindings to the Network
+Simulator, as explained in @ref pls. The most
+interesting is probably not the C files since they are unchanged from
+the other simulations, but the associated files, such as the platform
+file to see how to declare a platform to be used with the PLS bindings
+of SimGrid and the tesh file to see how to actually start a simulation
+in these settings.

+ - @ref examples/msg/network-ns3/network-ns3.c. Simple ping-pong using
+ ns-3 instead of the SimGrid network models.
+
+TODO: merge the C files
+
+TODO: show the XML files instead if it's what is interesting. On a "XML example files" page that does not exist yet.
+
+@subsection msg_ex_io Simulating disks and files
+
+The examples of this section demonstrate how to interact with the
+simulated storages.
+
+ - <b>Basic example</b>.
+ @ref examples/msg/io-storage/io-storage.c \n
+ All main storage and file functions are demoed.
+
+ - <b>File Management</b>. @ref examples/msg/io-file/io-file.c \n
+ This example illustrates the use of operations on file
+ (@ref MSG_file_open, @ref MSG_file_read, @ref MSG_file_write,
+ or @ref MSG_file_close).
