Trying to implement HTTPie's CLI with docopt.

docopt_httpie

#!/usr/bin/env python
"""
usage: http [METHOD] <URL> [REQUEST ITEM [REQUEST ITEM ...]]

HTTPie - cURL for humans. <http://httpie.org>

Positional arguments:
  These arguments come after any flags and in the order they are listed
  here. Only URL is required.

  METHOD                The HTTP method to be used for the request (GET, POST,
                        PUT, DELETE, PATCH, ...). If this argument is omitted,
                        then HTTPie will guess the HTTP method. If there is
                        some data to be sent, then it will be POST, otherwise
                        GET.
  URL                   The protocol defaults to http:// if the URL does not
                        include one.
  REQUEST ITEM          A key-value pair whose type is defined by the
                        separator used. It can be an HTTP header
                        (header:value), a data field to be used in the request
                        body (field_name=value), a raw JSON data field
                        (field_name:=value), a query parameter (name==value),
                        or a file field (field_name@/path/to/file). You can
                        use a backslash to escape a colliding separator in the
                        field name.

Suggestions and bug reports are greatly appreciated:
