+/**
+ * @addtogroup Ewl_Colorpicker
+ * @section image_tut Tutorial
+ *
+ * The Ewl_Colorpicker widget provides a way to let the user select a color
+ * either by manually entering its values, or graphically via the built-in
+ * Ewl_Spectrum widget, which also provides a preview of the color.
+ * The color can be selected in RGB or HSV format (but can be retrieved only
+ * in RGB format for now).
+ *
+ * @code
+ * Ewl_Widget *cp;
+ * cp = ewl_colorpicker_new();
+ * ewl_widget_show(cp);
+ * @endcode
+ *
+ * Once you've setup the colour picker, you can read its current and previous
+ * value and set them. For example the following swaps the two.
+ *
+ * @code
+ * unsigned int r,g,b;
+ * ewl_colorpicker_current_rgb_get(EWL_COLORPICKER(cp), &r, &g, &b);
+ * ewl_colorpicker_previous_rgb_set(EWL_COLORPICKER(cp), r, g, b);
+ * @endcode
+ *
+ * You can also change the display mode of the spectrum programmatically
+ *
+ * @code
+ * void ewl_colorpicker_color_mode_set(Ewl_Colorpicker *cp,
Ewl_Color_Mode type);
+ * Ewl_Color_Mode ewl_colorpicker_color_mode_get(Ewl_Colorpicker *cp);
+ * @endcode
+ *
