-HttpResponse class may be infunctional with current ZendEngine2,
-a fix is pending.
+HttpResponse class is only available for PHP >= 5.1
+HttpResponse::guessContentType() is not available on Windows at the time this
+was written. On other platforms you'll need to fix the magic.mime file that's
+shipped with PHP by executing `sed -e "s/\t!/\\\!/" magic.mime > magic.good`
+and using the new magic file.
