Do you know how to prevent indexing of pages past the home page in WP?
I mean I don't want `mysite.com/page/2`, `mysite.com/page/3` to be indexed.

This is because I use `home.php` for my theme, so that `page/2`, `page/3`
are all the same.

Please give me a hint or a code snippet please, I don't want to add another plugin (robots meta).
