			--check-hash-based-pycs always\|default\|never:

	-~~X tracemalloc: start tracing Python memory allocations using the~~
	~~tracemalloc module. By default, only the most recent frame is stored in a~~
	~~traceback of a trace. Use~~ -~~X tracemalloc=NFRAME to start tracing with a~~
	~~traceback limit of NFRAME frames~~
	-~~X importtime~~: ~~show how long each import takes. It shows module name,~~
	~~cumulative time (including nested imports)~~ and ~~self time (excluding~~
	~~nested imports). Note that its output may be broken in multi~~-~~threaded~~
	~~application. Typical usage is python3~~ -~~X importtime -c 'import asyncio'~~
	-~~X dev~~: ~~enable CPython's "development mode", introducing additional runtime~~
	~~checks which are too expensive to be enabled by default. Effect of the~~
	~~developer mode:~~
	* Add default warning filter, as -~~W default~~
	* Install debug hooks on memory allocators: see the PyMem_SetupDebugHooks() C function
	* Enable the faulthandler module to dump the Python traceback on a crash
	* Enable asyncio debug mode
	* Set the dev_mode attribute of sys.flags to True
	* io.IOBase destructor logs close() exceptions
	-X ~~utf8: enable UTF-8 mode for operating system interfaces, overriding the default~~
	~~locale~~-~~aware mode. -X utf8=0 explicitly disables UTF-8 mode (even when it would~~
	~~otherwise activate automatically)~~
	-~~X pycache_prefix=PATH: enable writing .pyc files to a parallel tree rooted at the~~
	~~given directory instead of to the code tree~~
	-~~X warn_default_encoding~~: ~~enable opt-in EncodingWarning for 'encoding=None'~~

	~~--check-hash-based-pycs always\|default\|never~~:		Arguments:
	~~control how Python invalidates hash-based .pyc files~~
	file : program read from script file		file : program read from script file
	- : program read from stdin (default; interactive mode if a tty)		- : program read from stdin (default; interactive mode if a tty)
	arg ...: arguments passed to program in sys.argv[1:]		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>/lib/pythonX.X.~~
	~~PYTHONPLATLIBDIR : override sys.platlibdir.~~
	~~PYTHONCASEOK : ignore case in 'import' statements (Windows).~~
	~~PYTHONUTF8: if set to 1, enable the UTF-8 mode.~~
	~~PYTHONIOENCODING: Encoding[:errors] used for stdin/stdout/stderr.~~
	~~PYTHONFAULTHANDLER: dump the Python traceback on fatal errors.~~
	~~PYTHONHASHSEED: if this variable is set to 'random', a random value is used~~
	~~to seed the hashes of str and bytes objects. It can also be set to an~~
	~~integer in the range [0,4294967295] to get hash values with a~~
	~~predictable seed.~~
	~~PYTHONMALLOC: set the Python memory allocators and/or install debug hooks~~
	~~on Python memory allocators. Use PYTHONMALLOC=debug to install debug~~
	~~hooks.~~
	~~PYTHONCOERCECLOCALE: if this variable is set to 0, it disables the locale~~
	~~coercion behavior. Use PYTHONCOERCECLOCALE=warn to request display of~~
	~~locale coercion and locale compatibility warnings on stderr.~~
	~~PYTHONBREAKPOINT: if this variable is set to 0, it disables the default~~
	~~debugger. It can be set to the callable of your debugger of choice.~~
	~~PYTHONDEVMODE: enable the development mode.~~
	~~PYTHONPYCACHEPREFIX: root directory for bytecode cache (pyc) files.~~
	~~PYTHONWARNDEFAULTENCODING: enable opt-in EncodingWarning for 'encoding=None'.~~
