android - How do you create an app that only allows horizontal orientation?

Question

I'm currently creating a side-scroller style game for my final year project for my degree.

I'm just wondering how you make the menu designed for when the phone is in horizontal orientation display, even when the phone is held in it's vertical orientation?

i.e. I want the user to know that the game has to be played with the phone in it's horizontal orientation and want the menu's to only display in the horizontal orientation.

Many thanks in advance.
