 this is an example of an android library project that has some reusable
 code that exposes part of OpenCV to android. In particular this provides a
 native camera interface for loading live video frames from the android camera
 into native opencv functions(as cv::Mat's)
 
-to build make sure you have swig and the crystax ndk in your path
+pre-reqs:
+* build the opencv/android libraries - up one directory
+* you need swig in you path for android-jni
+    on ubuntu - sudo apt-get install swig
+    others: http://www.swig.org/

 that should work...  If it doesn't make sure to edit the generated local.env.mk
-the key variable
+to reflect your machine's setup
 
-more later on how to build actual project for android 
-    - see the code.google.com/p/android-opencv for details on this
