- * @subsection MSG_ex_resources Other resource kinds
- * 
- * This section contains some sparse examples of how to use the other
- * kind of resources, such as disk or GPU. These resources are quite
- * experimental for now, but here we go anyway.
- * 
- * - <b>io/file.c</b> Example with the disk resource
+ * - <b>File management: io-file/io-file.c</b>. 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).
