ClearCurvatureRelations[cd] removes the automatic curvature relations for the covariant derivative cd. |

- The curvature relations are replacement rules that send contractions of the Riemann tensor to the Ricci tensor or Ricci scalar.

- The curvature relations are usually set during the definition of a covariant derivative or metric through the option CurvatureRelations.

- The following options can be given:

- Possible settings for Verbose include:
