RewriteRule to strip www.?

I’m trying to add a RewriteRule to my .htaccess to remove the www.
prefix from requests. The following works on its own:

RewriteCond %{HTTP_HOST}
RewriteRule (.*)$1

But it blows up when I try to add it to my .htaccess file. I’ve tried
moving it around, before and after the various Rails-specific rules, but
I can’t get it to work.

Is it possible? Any suggestions?
