Anthology of Ideas

I was sick of having a half dozen different plugins to add meta tags and fix the robots, so I wrote a plugin that prevents duplicate content from being indexed by Google, adds useful meta tags, and ensures that all posts are at one single permalink (using 301 redirects of course). This is more a shell of a plugin than an actual plugin as there are no options, and there are obvious flaws such as it doesn’t allow you to use paged posts. If you want to make changes you will have to do it yourself.

Copy the following into a php file. Upload it. If you need any more instructions than that, you are better off using a plugin that is a little more user friendly because using this plugin incorrectly can kill your site.
