Hello,

I use emacs on my desktop and laptop, and unison to synchronize
modified files between the machines.

But that means that after synchronization, some of the files that a
buffer is visiting will change, and I will have to revert the buffer.
I would like to automatically revert all such buffers.  What function
can I use to test whether a the file that a buffer is visiting has
changed?

Thanks,

Mirko
