<p>
<a href="AcceptMediaTypes.html">AcceptMediaTypes</a> is intended for
wrapping env[‘HTTP_ACCEPT’].
</p>
<p>
It allows ordering of its values (accepted media types) according to their
"quality" (preference level).
</p>
<p>
This wrapper is typically used to determine the request‘s <a
href="AcceptMediaTypes.html#M000124">prefered</a> media type (see example
below).
</p>
<h5>Examples</h5>
<pre>
env['HTTP_ACCEPT'] #=> 'application/xml;q=0.8,text/html,text/plain;q=0.9'
types = Rack::AcceptMediaTypes.new(env['HTTP_ACCEPT'])
types #=> ['text/html', 'text/plain', 'application/xml']
types.prefered #=> 'text/html'
</pre>
<h5>Notes</h5>
<p>
For simplicity, media type parameters are striped, as they are seldom used
in practice. Users who need them are excepted to parse the Accept header
manually.
