Empty the Trash Automatically When You Exit Eudora

If I ever empty my CD/mp3/AAC (or whatever form canned music will have assumed by then), you won't find recordings of Granados' Danzas españolas (for the piano or, better known, adapted for guitar) in the trash.
Eudora takes the trash out for you! Here's how to make Eudora empty the "Trash" folder when you exit.
