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.
