Query: Stokes Theorem and the Equations of GRMHD   This paper provides an alternate derivation of the equations used in the
GRMHD code of De Villiers and Hawley using Stokes Theorem. This derivation
places the published form of the discretized equations of GRMHD in a broader
context, and suggests possible future directions for numerical work.
