Meta Tags in ASP.NET using MasterPage and ContentPlaceHolders

Having META tags like Description and Keywords on the .aspx pages of our sites is important. It is also important that the content of the tags be easily added/updated. There are different ways of resolving this need. My solution doesn't require the creation of the actual html markup (tags) on every page; just the meta content is all you'll need to add (the important stuff). In addition, the placeholders will be added automatically when the page is created! Simple, straightforward, and intention revealing.
