145 Start a simple web server for serving the API.

148 from the current project directory. This webserver is only suitable
149 for testing and development. Do not use it in production setups!
151 There are different webservers available. The default 'php' engine
152 runs the classic PHP frontend. The other engines are Python servers
153 which run the new Python frontend code. This is highly experimental
154 at the moment and may not include the full API.
