+            dlib comes with a graphical tool for annotating images with
+            labeled rectangles.  The tool produces an XML file containing these
+            annotations.  Therefore, load_image_dataset_metadata() is a routine
+            for parsing these XML files.
+            <p>
+               The graphical annotation tool can be found in the tools/imglab
+               folder and compiled with the following commands.
+<code_box>
+cd tools/imglab
+mkdir build
+cmake ..
+make
+</code_box>

+            This routine is a tool for saving labeled image metadata to an 
+            XML file.  In particular, this routine saves the metadata into a
+            form which can be read by the <a href="#load_image_dataset_metadata">load_image_dataset_metadata</a>
+            routine.
