+/*
+* This is example of 3d-shooter done with help of evas-3d
+*
+* Basic control: 'w' - to  go forward, 's' - to go back, 'a' - to the left, 'd' - to the right,
+* right mouse down - to activate camera rotation, mouse wheel down - to deactivate camera rotation,
+* left mouse down - to fire, 'space' - to jump. The warrior is atackable, the snake isn't,
+* this possibility is given by presence of the bounding box, which fixes the rocket entry.
+* The warrior isn't passable for camera, neither is wall. There is a possibility to go upstairs
+* and break down.
+*
+* Compile with "gcc -g evas-3d-shooter.c evas-3d-shooter-header.c -o evas-3d-shooter `pkg-config --libs --cflags evas ecore ecore-evas eo` -lm"
