[maemo-developers] Noob question re Qt Application structure

[From: ianare at gmail.com]

Right, one way is to have two separate deb packages, making the GUI depend on the daemon. This is expecially useful if you envision the daemon to be accessed by other apps or does not need the GUI in all cases.
Another way is to package both apps (executables) in the same deb package.
