PoP as soon as I finish v 0.5 ill write tutorial on making your own packages.
Whole process is fairly easy. There is nothing more than renaming these files, adding some if mod is suposed to be bilingual, editing *.hdr config files and finally preparing installer with launchpad script/update tool, which moves original files to safe directory and creates symbolic links to new voices on usb storage. Nothing really special...
I'm glad it works for you, guys.
Cheers.
