Subject: lots of changes ! 1. switch to a new build system based on automake
 (because we need to check for some lib on ./configure before make) 2. sort
 files in different directory 3. add some new features (some of them need
 OpenCV >= 2.4.5)

+#X text 37 37 getting started with camera calibration :;
+#X text 65 123 3 Check calibration toggle to start and move the chessboard
+in front of the camera (or move the camera in front of your screen).
+Your computer may slow down during searching chessboard corners. When
+all corners are found it takes a snapshot (and the image will be negative)
+;
+#X text 65 103 2 Plug a supported camera and start rendering;
+#X text 66 73 1 Print the chessboard ona rigid paperboard (or just
+show it on the screen);
+#X text 65 194 4 When enought chessboard have been found (20 by default)
+it computes transformation matrix and map to undistord the image;
+#X text 65 244 5 Then all incoming images are undistord \, you can
+save the transformation and distorsion matrix to files to load it next
