evenpage – Ensure that the total number of pages is even

The pack­age en­sures that the num­ber of pages gen­er­ated by LaTeX is even: if it is odd, an empty page is added at the end, with noth­ing on it (nei­ther page num­ber, head­ers nor foot­ers).
The pack­age is dis­tributed as part of the bo­si­sio col­lec­tion.
