WordPress adds all kinds of <code><meta></code>-tags to the <code><head></code> section of your site. 
Some of these tags are quite good and have real uses, others make sense for some sites and others doesn’t. 
Some tags are even considered a security risk, since they tell the world which version of WordPress you’re currently running.
This plugin allows you to remove all of the <code><meta></code>-tags that WordPress outputs by default. 
You decide on a tag-by-tag basis which tags to remove and which to keep. Nothing’s enforced, you’re 100% in charge.
