Help finding the last translated rev. number

[Federico Caminiti]

Hi,

You might remember me as the person who posted a translation script a few
months ago [1] .

I'm having trouble finding what the last translation rev. for a given
document is. If anyone has any useful pointers of advice, it would be very
welcome.

Cheers!
