 * This plugin uses code from my plugin WP No Category Base without attribution.
   This is open source but attribution is common courtesy.

 * Yes, I did refer to WP No Category Base when coding SEO Ultimate’s Permalink 
   Tweaker. At the time, I figured attribution wasn’t required because the plugins
   were different enough that the only line of code they shared in common was `global
   $wp_rewrite;`. However, I should’ve included attribution, since it was partly
   a derivative work. I’m sorry for the oversight and I’ll add a code attribution
   to the next release.
