Generic htaccess redirect www to non-www

I would like to redirect www.example.com to example.com. The following htaccess code makes this happen:

RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]

But, is there a way to do this in a generic fashion without hard coding the domain name?
