- .pyc extension; also PYTHONOPTIMIZE=x\n\

- can be supplied multiple times to increase verbosity\n\
--V : print the Python version number and exit (also --version)\n\
- when given twice, print more information about the build\n\
--W arg : warning control; arg is action:message:category:module:lineno\n\

--x : skip first line of source, allowing use of non-Unix forms of #!cmd\n\
--X opt : set implementation-specific option. The following options are available:\n\
-\n\
- -X faulthandler: enable faulthandler\n\
- -X oldparser: enable the traditional LL(1) parser; also PYTHONOLDPARSER\n\
- -X showrefcount: output the total reference count and number of used\n\
- memory blocks when the program finishes or after each statement in the\n\
- interactive interpreter. This only works on debug builds\n\
- -X tracemalloc: start tracing Python memory allocations using the\n\
- tracemalloc module. By default, only the most recent frame is stored in a\n\
- traceback of a trace. Use -X tracemalloc=NFRAME to start tracing with a\n\
- traceback limit of NFRAME frames\n\
- -X importtime: show how long each import takes. It shows module name,\n\
- cumulative time (including nested imports) and self time (excluding\n\
- nested imports). Note that its output may be broken in multi-threaded\n\
- application. Typical usage is python3 -X importtime -c 'import asyncio'\n\
- -X dev: enable CPython's \"development mode\", introducing additional runtime\n\
- checks which are too expensive to be enabled by default. Effect of the\n\
- developer mode:\n\
- * Add default warning filter, as -W default\n\
- * Install debug hooks on memory allocators: see the PyMem_SetupDebugHooks() C function\n\
- * Enable the faulthandler module to dump the Python traceback on a crash\n\
- * Enable asyncio debug mode\n\
- * Set the dev_mode attribute of sys.flags to True\n\
- * io.IOBase destructor logs close() exceptions\n\
- -X utf8: enable UTF-8 mode for operating system interfaces, overriding the default\n\
- locale-aware mode. -X utf8=0 explicitly disables UTF-8 mode (even when it would\n\
- otherwise activate automatically)\n\
- -X pycache_prefix=PATH: enable writing .pyc files to a parallel tree rooted at the\n\
- given directory instead of to the code tree\n\
