+
+It's current reach is short, but tested and expected to grow over time. 
+
+

+2. Show those CGRect structures who is the boss. 
+

+Use
+---
+
+1. The following function headers self-explain the reach of the library. 
+Note that the CGRect structure to modify should be passed by reference. 
+
+```obj-c
+void CGRectSetSize(CGRect *rect, CGSize size);
+void CGRectSetWidth(CGRect *rect, CGFloat width);
+void CGRectSetHeight(CGRect *rect, CGFloat height);
+
+void CGRectSetOrigin(CGRect *rect, CGPoint originPoint);
+void CGRectSetX(CGRect *rect, CGFloat x);
+void CGRectSetY(CGRect *rect, CGFloat y);
+```
