+/*! \page line_model_monitor_page Telephone line model monitoring
+\section line_model_monitor_page_sec_1 What does it do?
+This code controls a GUI window, which provides monitoring of the internal status
+of a telephone line modem. It shows, graphically:
+
+    - the spectrum of the received signal.
+    - the line model in use (when a known line model is being used).
+    - the adapted coefficients of the canceller.
+
+\section line_model_monitor_page_sec_2 How does it work?
+This code uses the FLTK cross platform GUI toolkit. It works on X11 and Windows platforms.
+In addition to the basic FLTK toolkit, fltk_cartesian is also required.
