hinting on xgridfit/fontforge - help needed


Since something like one or two months ago i started to do my first approach on hinting, but i'm only using software-libre on typeface designing (like Fontforge instead on Fontlab, Inkscape instead of Illustrator, etc.)

The problem is Fontforge has no direct hinting support, and it needs an external help from a tool named xgridfit.

Do someone know how this work, and how can we efficiently work on it and Fontforge together? If it is, are there some useful and simple to follow documentation?

Thanks in advance! :)
