Description

Matthew Brush said in another thread that mousepad-window-ui.h "despite being checked into Git, is also (re)generated from mousepad-window-ui.xml, but only when --enable-maintainer-mode is passed to configure script AFAIK."

Actually, it isn't checked into Git. But it would be nice for people who don't use the rest of XFCE if it was, because they wouldn't have to install exo and its dependencies to build from Git.
