How can I use .htaccess to automatically chmod a folder?

I'm looking at this article http://www.jwrmedia.com/lessons/htaccess/automatic-chmod

So, I want more details about this method.

Thanks.

• I believe the article lies, and there is no such feature for htaccess files.

  I could not find a reference to this directive in the apache documentation or source code.
