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.

Cheers,
Paul
