 =head1 DESCRIPTION
 
 This module defines an object containing a Hermite spline approximation to a function.
-  The approximation
-consists of a piecewise cubic polynomial which agrees with the original
-function and its first derivative at
-the node points.
+The approximation consists of a piecewise cubic polynomial which agrees with the original
+function and its first derivative at the node points.
 
 This is useful for creating on the fly graphics.  Care must be taken to use a small
 number of points spaced reasonably far apart, preferably
