At http://w3.pppl.gov/~hongqin/computerAlgebra.htm you will find reference to a Symbolic Vector Analysis package developed by Hong Qin. I have made a few minor changes to his Package (correcting some formatting bugs) and put his Package, Notebooks, and PDF files at http://www.physics.uwa.edu.au/pub/Mathematica/Calculus/ I suggest putting GeneralVectorAnalysis.m into a folder called Calculus in the directory returned by evaluating $UserAddOnsDirectory.
