another reason to move lng and wps out of the zip is because even if
ppl do use a different language from english.. they would only use one
other file.. so y put them all in the zip.. sort of the same for
wps... and fonts.
can he lng's be moved to a seperate part of the dowload page? (have a
drop list with the available languages, and another for the targets,
then a button and it will upload the correct file to u..?)
