BTW, the two latex printers should have the same name, not one LaTexPrinter and the other one LatexPrinter, so please rename your printer to LatexPrinter (and open an issue if you feel that sympy's LatexPrinter should be renamed to LaTeXPrinter) more things. Why is there still a sympy/galgebra/doc/ directory ? Isn't now all files in doc/src/modules/galgebra ? can it be removed?
