The "pyperf command" tool be used instead. Example:
$ python3 -m pyperf command -- python3 -c pass
.....................
command: Mean +- std dev: 17.8 ms +- 0.4 ms
pyperf also computes the standard deviation which gives an idea of
the benchmark looks reliable or not.
Remove outdated example scripts of the Tools/scripts/ directory:
* gprof2html.py
* md5sum.py
* nm2def.py
* pathfix.py
* win_add2path.py
Remove test_gprof2html, test_md5sum and test_pathfix of test_tools.
Remove diff.py and ndiff.py scripts of Tools/scripts/: move them to
Doc/includes/.
* diff.py and ndiff.py files are no longer executable. Remove also
their shebang ("#!/usr/bin/env python3").
* Remove the -profile command from ndiff.py to simply the code.
* Remove ndiff.py copyright and history command. The Python
documentation examples are distributed under the "Zero Clause BSD
License".
Relevant tests moved from test_exceptions to test_traceback to be able to
compare both implementations.

Remove the sys.getdxp() function and the Tools/scripts/analyze_dxp.py
script. DXP stands for "dynamic execution pairs". They were related
to DYNAMIC_EXECUTION_PROFILE and DXPAIRS macros which have been
removed in Python 3.11. Python can now be built with "./configure
--enable-pystats" to gather statistics on Python opcodes.
Fix a shell code injection vulnerability in the
get-remote-certificate.py example script. The script no longer uses a
shell to run "openssl" commands. Issue reported and initial fix by
Caleb Shortt.
Remove the Windows code path to send "quit" on stdin to the "openssl
s_client" command: use DEVNULL on all platforms instead.

Add script ``Tools/scripts/check_modules.py`` to check and validate builtin
and shared extension modules. The script also handles ``Modules/Setup`` and
will eventually replace ``setup.py``.

* Move Lib/lib2to3/tests/ to Lib/test/test_lib2to3/.
* Remove Lib/test/test_lib2to3.py.
* Update imports.
* all_project_files(): use different paths and sort files
to make the tests more reproducible.
* Update references to tests.
Remove the token.h header file. There was never any public tokenizer
C API. The token.h header file was only designed to be used by Python
internals.
Move Include/token.h to Include/internal/pycore_token.h. Including
this header file now requires that the Py_BUILD_CORE macro is
defined. It no longer checks for the Py_LIMITED_API macro.
Rename functions:
* PyToken_OneChar() => _PyToken_OneChar()
* PyToken_TwoChars() => _PyToken_TwoChars()
* PyToken_ThreeChars() => _PyToken_ThreeChars()
Also updated `make -C htmlview` so it used a full path with `file://`, because the original didn't open the page (macOS).
For example:
```sh
cd Doc
# Doesn't open anything:
python3 -c "import webbrowser; webbrowser.open('build/html/index.html')"
# Opens the docs page e.g. file:///Users/hugo/github/cpython/Doc/build/html/index.html :
python3 -c "import os, webbrowser; webbrowser.open('file://' + os.path.realpath('build/html/index.html'))"
```

Move the following API from Include/opcode.h (public C API) to a new
Include/internal/pycore_opcode.h header file (internal C API):
* EXTRA_CASES
* _PyOpcode_Caches
* _PyOpcode_Deopt
* _PyOpcode_Jump
* _PyOpcode_OpName
* _PyOpcode_RelativeJump
Apparently a switch on an 8-bit quantity where all cases are
present generates a more efficient jump (doing only one indexed
memory load instead of two).
So we make opcode and use_tracing uint8_t, and generate a macro
full of extra `case NNN:` lines for all unused opcodes.
