This command makes an artifical request to a web application that
uses a paste.deploy configuration file for the server and
application.
Use 'paster request config.ini /url' to request /url. Use
'paster post config.ini /url < data' to do a POST with the given
request body.
If the URL is relative (doesn't begin with /) it is interpreted as
relative to /.command/. The variable environ['paste.command_request']
will be set to True in the request, so your application can distinguish
these calls from normal requests.
Note that you can pass options besides the options listed here; any unknown
options will be passed to the application in environ['QUERY_STRING'].
