gh-97681: Remove Tools/demo/ directory

[vstinner]

Remove the following old demo scripts:

• beer.py
• eiffel.py
• hanoi.py
• life.py
• markov.py
• mcast.py
• queens.py
• redemo.py
• rpython.py
• rpythond.py
• sortvisu.py
• spreadsheet.py
• vector.py

Changes:

• Remove a reference to the redemo.py script in the regex howto documentation.
• Remove a reference to the removed Tools/demo/ directory in the curses documentation.
• Update PC/layout/ to remove the reference to Tools/demo/ directory.

• Issue: Remove old Tools/demo/ scripts #97681

[vstinner]

Remove a reference to the removed Tools/demo/ directory in the curses documentation.

In fact, only Tools/demo/life.py uses the curses module.

Should I add a link to it in the changelog entry ?

[gvanrossum]

Sure!

[vstinner]

I added a link to https://github.com/gvanrossum/old-demos in the change documentation, and I documented the removal of Demos in What's New in Python 3.12.

Goodbye old demos, enjoy your new home: https://github.com/gvanrossum/old-demos

I looked at the first author of each removed demo:

• Guido van Rossum:

  • mcast (1992)
  • vector (1992)
  • markov (1993)
  • hanoi (1994)
  • rpython (1995)
  • sortvisu (1997)
  • beer (1998)
  • redemo (1998)
  • queens (2000)
  • spreadsheet (2002)

• Andrew M. Kuchling: life (2000)

• Jeremy Hylton: eiffel (2002)

Demos were created between 1992 and 2002, and Guido wrote most of them (10 of 12).
