+* This example illustrates the work of different callbacks of events from mouse
+* and keyboard.
+*
+* Next tests are available:
+* 1. All animations of scene will stop on mouse click on the background.
+* 2. Clicking of any object on scene causes stop of its movement, but if click
on
+* the moon while it is in front of a planet will stop them both.
+* 3. Camera position can be changed by pressing 'down' or 'up' key. Position of
+* the camera changes in the respective direction.
+* 4. The 'n' key pressing returns camera to its default position.
+* 5. One of four types of vertex assembly of planet could be chosen by
clicking on
+* a number from 1 to 4 on keyboard.
+
+* Compile with:
+* gcc -o evas-3d-moon-space evas-3d-moon-space.c -g `pkg-config --libs
--cflags evas ecore ecore-evas eo` -lm
