+     "This package provides the @code{@@muladd} macro.  It automatically 
converts
+expressions with multiplications and additions or subtractions to calls with
+muladd which then fuse via FMA when it would increase the performance of the
+code.  The @code{@@muladd} macro can be placed on code blocks and it will 
automatically
+find the appropriate expressions and nest muladd expressions when necessary.  
In
+mixed expressions summands without multiplication will be grouped together and
+evaluated first but otherwise the order of evaluation of multiplications and
+additions is not changed.")
