localization question...

how do i localize the applescripts? i have found out that i can select the different nib files and choose to add a localization. yet i only have one applescript in which pop-up messages are only in english. i have found out that i can use the localization.string file and tables for the script messages… yet the problem with this is that i do not know how i add such a file into the .nib file?

thanks
