Additional packages for texlive?

Hi, @holzschu.

First of all, thanks a lot for such a great tool as a-shell! It's a pleasure to have C/C++, Python and *TeX working on an iPad.

And my apologies if the question is silly. I wonder if one can download an additional package for texlive and put it in `~/Library/texlive/texmf-local/` so that the *TeX engines would be able to find it? (I tried it but `pdflatex` failed to see the packages I put there. Is there a package caching step I am missing?)

Thanks,
Alexey
