Package: devscripts
Version: 2.10.55
Severity: wishlist
Tags: patch

Hi,

At the moment, the diff2patches manpage is sort of sparse. I think it
should document that the debian directory is the default if
debian/patches doesn't exist, and clarify whether the patches are
broken up and how they are named.

I had to go into the source to get this information, and I've attached
a simple patch that I think makes this clearer in the manpage.

Regards,
Daniel
