Computing the components of the curvature tensor is tedious, are there other methods?

I've been trying to calculate the Riemann Curvature Tensor for a certain manifold in 3-dimensional Euclidean Space using Christoffel Symbols of the second kind, and so far everything has gone well however...

It is extremely tedious and takes a very long time; there is also a high probability of making silly mistakes (like misplacing a variable). Are there any faster methods (not necessarily simpler) or is there no other alternative?

 Recognitions: Science Advisor The equations simplify with respect to an orthonormal basis. For a surface, if dx and dy are a local orthonormal basis for the 1 forms, then dx = w$_{12}$^dy and dy = -w$_{12}$^dx dw$_{12}$ = -KdV where K is the Gauss curvature and dV is the volume element of the metric.
