+usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
+Options and arguments (and corresponding environment variables):
+-B     : don't write .py[co] files on import; also PYTHONDONTWRITEBYTECODE=x
+-c cmd : program passed in as string (terminates option list)
+-d     : debug output from parser; also PYTHONDEBUG=x
+-E     : ignore PYTHON* environment variables (such as PYTHONPATH)
+-h     : print this help message and exit (also --help)
+-i     : inspect interactively after running script; forces a prompt even
+         if stdin does not appear to be a terminal; also PYTHONINSPECT=x
+-m mod : run library module as a script (terminates option list)
+-O     : optimize generated bytecode slightly; also PYTHONOPTIMIZE=x
+-OO    : remove doc-strings in addition to the -O optimizations
+-R     : use a pseudo-random salt to make hash() values of various types be
+         unpredictable between separate invocations of the interpreter, as
+         a defense against denial-of-service attacks
+-Q arg : division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew
+-s     : don't add user site directory to sys.path; also PYTHONNOUSERSITE
+-S     : don't imply 'import site' on initialization
+-t     : issue warnings about inconsistent tab usage (-tt: issue errors)
+-u     : unbuffered binary stdout and stderr; also PYTHONUNBUFFERED=x
+         see man page for details on internal buffering relating to '-u'
+-v     : verbose (trace import statements); also PYTHONVERBOSE=x
+         can be supplied multiple times to increase verbosity
+-V     : print the Python version number and exit (also --version)
+-W arg : warning control; arg is action:message:category:module:lineno
+-x     : skip first line of source, allowing use of non-Unix forms of #!cmd
+-3     : warn about Python 3.x incompatibilities that 2to3 cannot trivially fix
+file   : program read from script file
+-      : program read from stdin (default; interactive mode if a tty)
+arg ...: arguments passed to program in sys.argv[1:]
+
+Other environment variables:
+PYTHONSTARTUP: file executed on interactive startup (no default)
+PYTHONPATH   : ':'-separated list of directories prefixed to the
+               default module search path.  The result is sys.path.
+PYTHONHOME   : alternate <prefix> directory (or <prefix>:<exec_prefix>).
+               The default module search path uses <prefix>/pythonX.X.
+PYTHONCASEOK : ignore case in 'import' statements (Windows).
+PYTHONIOENCODING: Encoding[:errors] used for stdin/stdout/stderr.
+PYTHONHASHSEED: if this variable is set to 'random', the effect is the same
+   as specifying the -R option: a random value is used to seed the hashes of
+   str, unicode, buffer and datetime objects.  It can also be set to an
+   integer in the range [0,4294967295] to get hash values with a predictable
+   seed.
