+ idle [-dns] [-t title] - [arg]*
+
+ -h print this help message and exit
+ -n run IDLE without a subprocess (see Help/IDLE Help for details)
+
+The following options will override the IDLE 'settings' configuration:
+
+ -e open an edit window
+ -i open a shell window
+
+The following options imply -i and will open a shell:
+
+ -c cmd run the command in a shell, or
+ -r file run script from file
+
+ -d 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"
