+Handling the statistical distributions is very similar except that now
+the macro BOOST_MATH_DECLARE_DISTRIBUTIONS accepts two parameters: the
+floating point type to use, and the policy type to apply. For example:
+
+ BOOST_MATH_DECLARE_DISTRIBUTIONS(double, mypolicy)
+
+Results a set of typedefs being defined like this:
+
+ typedef boost::math::normal_distribution<double, mypolicy> normal;
+
+The name of each typedef is the same as the name of the distribution
+class template, but without the "_distribution" suffix.
