gprof2html.py

Created in 2002 by @gvanrossum. Following changes are mostly coding styles changes, no feature or bugfix.

I didn't use gprof format for a long time. There are now many tools to profile programs with nice UI. I don't think that maintaining such tool in Python with a HTML output is still relevant today.

md5sum.py

If someone wants such feature as part of Python, I would suggest to add a command line interface (CLI) to the hashlib module instead.

The script doesn't support multithreading, whereas Python releases the GIL in hashlib. The script uses the old getopt module.

@gvanrossum wrote in 2001:

This is a trivial command line utility to print MD5 checksums.
I published it on the web as http://www.python.org/2.1/md5sum.py
so I thought I might as well check it in.

Well, I don't think that it's still relevant in 2022. There are now many ways to easily distribute Python scripts (pip, GitHub, whatever works).

nm2def.py

Helpers to extract symbols from Unix libs and auto-generate
Windows definition files from them. Depends on nm(1). Tested
on Linux and Solaris only (-p option to nm is for Solaris only).

@malemburg: if you still use this script, it should be maintained outside Python. Python doesn't use it.

pathfix.py

@hroncok: Script used by Fedora, see: https://discuss.python.org/t/remove-outdated-tools-scripts-scripts/19571/35

It can be maintained somewhere else.

win_add2path.py

Not used by the Windows installer: https://discuss.python.org/t/remove-outdated-tools-scripts-scripts/19571/20
