Current page front page or something else? [Solved]

[f00ty]

I'd like to detect is the current page the front page or something else. That way, I could place H1 tags to somewhere else in front page than in other sites in index. How can I detect with php is the current page the front page?

Can this be made with $board_info?

Edit: Yes, it can be done with $board_info == null.
