zenity --info --text "Some important info about this language pack.

In the future if you plan to remove or upgrade firefox, you must
uninstall this language pack first. Otherwise when firefox is
uninstalled, it will leave the language pack files and directory
tree behind. It probably won't hurt anything, other than leave 
unwanted cruft on your computer.

If your Vectorlinux locale is set the same as this language pack,
no furthur configuring is required.  A preferences file has been
installed in Firefox so Firefox will match lanquage packs
(if installed) to whatever locale your machine is using."
