   1 /* Boost interval/io.hpp header file
   2  *
   3  * This file is only meant to provide a quick
   4  * implementation of the output operator. It is
   5  * provided for test programs that aren't even
   6  * interested in the precision of the results.
   7  * A real progam should define its own operators
   8  * and never include this header.
