   <b>Synopsis</b>.
    Setup the loop device at &lt;dev-path&gt; to access the file at &lt;file-path&gt; as a block device.
-   Example:
+   In the following example a 256Kb file is created (<code>dd</code>) and <code>losetup</code> is
+   used to make the file accessible as a block device. 
+   A FAT file system is created (<code>mkfatfs</code>) and mounted (<code>mount</code>).
+   Files can then be managed on the loop-mounted file.
