Hmm.. it redefines HOME only for Emacs so that .emacs.d, .gnupg etc. go there 
and not in %APPDATA%

I have seen it 
(https://www.gnu.org/software/emacs/manual/html_mono/emacs.html#Misc-Variables) 
but I didn't understand much. Really defining

emacs_dir=%~dp0..\

in the .bat make .emacs.d go on the portable device?

May you give a concrete example? Thanks.
