- libshotscope - (wip) golf ball trajectory calculation
+ libshotscope - golf ball trajectory calculation
 
 Much of the math here is based on [work done](http://baseball.physics.illinois.edu/trajectory-calculator-golf.html) by Prof. Alan M. Nathan at the  University of Illinois Urbana-Champaign. I turned it into a C++ library and incorporated tests.
 
+See `examples/`.
