I think you are talking about the scripts. When you chose a script for scraping info from you favourite website you can decide between different scripts. Some of them are only in their native language but others are multilingual. This last kind of scripts are configurable in their own Script Options which you can reach when selecting a script for importing info. As example TheMovieDB.org grabs info in german, english, italian, french or spanish (Language: DE|EN|IT|FR|ES). Once set the complete script options are stored and next time you want to use it you don't have to set them again.
In order to achieve what is possible, you have to try the impossible over and over again. Hermann Hesse
