enable the debugger
  -s         run $IDLESTARTUP or $PYTHONSTARTUP before anything else
  -t title   set title of shell window

A default edit window will be bypassed when -c, -r, or - are used.

[arg]* are passed to the command (-c) or script (-r) in sys.argv[1:].

Examples:

idle
        Open an edit window or shell depending on IDLE's configuration.

idle foo.py foobar.py
        Edit the files, also open a shell if configured to start with shell.

idle -est "Baz" foo.py
        Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell
        window with the title "Baz".

idle -c "import sys; print(sys.argv)" "foo"
        Open a shell window and run the command, passing "-c" in sys.argv[0]
        and "foo" in sys.argv[1].

idle -d -s -r foo.py "Hello World"
        Open a shell window, run a startup script, enable the debugger, and
        run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
        sys.argv[1].

echo "import sys; print(sys.argv)" | idle - "foobar"
        Open a shell window, run the script piped in, passing '' in sys.argv[0]
        and "foobar" in sys.argv[1].
