This is a so-called router for the the internal PHP Web server:
<http://php.net/manual/en/features.commandline.webserver.php>

It is used to test feed parsing in a controlled environment, 
answering specific requests used in tests with the data required
to pass the test. 

The parameters of the responses are kept in separate files, 
which include the following data:

- Response content
- Response code
- Content type
- Whether to send cache headers
- Last modified
- Any other headers
