About rescaling view to cover screen in multiple resolutions

Hi,

I have been using 2dtoolkit for the past 2 years and it is really good but I want now to use the sprite system in unity 5. One of the things I loved from 2dtoolkit was its camera system. There you could for example build the game for a native resolution of 960x640 and let the camera rescale it to cover any other resolution. Yes, I know there could be some distortion because aspect ratio is not the same, etc... but for me it is ok. Do anybody know if it is possible to accomplish this easily with unity3d 2d system? Must I have to fight agains the camera settings to adapt the viewport to the resolution the game is running on?

Cheers.
