"""
Example script to control a Scrapy server using its JSON-RPC web service.
It only provides a reduced functionality as its main purpose is to illustrate
how to write a web service client. Feel free to improve or write you own.
Also, keep in mind that the JSON-RPC API is not stable. The recommended way for
controlling a Scrapy server is through the execution queue (see the "queue"
command).
