The DifferentialGeometry:-Tools sub-package contains a number of utility procedures which are used primarily in the development of new DifferentialGeometry applications.
Each of the commands in the DifferentialGeometry:-Tools package can only be accessed by first executing with(DifferentialGeometry) and with(Tools), in that order or by using the long form of the command DifferentialGeometry:-Tools:-Command(...).
