+     "The package provides straightforward ways to define three-dimensional
+coordinate frames through which to plot in TikZ.  The user can specify the
+orientation of the main coordinate frame, and use standard TikZ commands and
+coordinates to render their @code{tikzfigure}.  A secondary coordinate frame
+is provided to allow rotations and translations with respect to the main
+coordinate frame.  In addition, the package can also handle plotting
+user-specified functions in spherical polar coordinates, where both the radius
+and fill color can be expressed as parametric functions of polar angles.")
