This package contains the plate tectonic programs **backtracker**,
which you can use to move geologic markers forward or backward in time,
**grdrotater** which rotates entire grids using a finite rotation,
**hotspotter** which generates CVA grids based on seamount locations
and a set of absolute plate motion stage poles, **originator**,
which associates seamounts with the most likely hotspot origins, and **rotconverter**
which does various operations involving finite rotations on a sphere. The package
is maintained by Paul Wessel.
