User:The Auto-categorizing Robot

I am robot written in Perl by ThaddeusB. My purpose is, shockingly enough, to automatically add categories to articles.

My first task is to add or update National Register of Historic Places historic district categories onto articles that use the infobox nrhp template. The task is based on this request. For complete explanation of how this will be done, see the BRFA. For a log of all pages examined during this task, see this page.
