If we write a web service, we'll probably need to validate and convert _MIME_ types to their file extension. For example, when a request comes into the server with an **_Accept_** header of _`application/javascript`_, we must know how to handle this _MIME_ type and render a `.js` template. 


Learn how to use metaprogramming for MIME library goals of supporting text in character sets other than ASCII.
