Two more PRs now in the "main" branch

[Edward K. Ream]

​PR #4970 retires three obsolete plugins, moving them to Leo's attic.

PR #4971 is more consequential. It streamlines Leo's installation machinery in preparation for supporting Python 3.15. Leo issue #4974 suggests updating Leo's documentation, including user docs.

This PR removes requirements.txt. From now on, install Leo's dependencies by running

    pip install .

from the top-level leo-editor folder.

Please keep testing Leo's main branch.

I did another quick test of 'main' branch on Debian & Fedora.

Everything looks good so far, i.e. 'ty_leo' script reports all checks as passed !

I am planning to check with Fedora 45 & Python 3.15.0-rc2 tomorrow.

Excellent. Thanks for your testing.

Glad to hear it. You may have to remove the dependency on matplotlib (in pyproject.toml) to get `pip install .` to work on 3.15.0-rc2.

See matplotlib issue #32280.

Hello Edward,

After applying your recommended change everything went fine with Fedora 45.

Now comes the interesting additional test: I did the same with Python 3.15.0rc2 on Debian 13 as well - and - it worked even without applying your recommended change !

It looks like the two distributions are building the wheels somewhat differently ...

In short: everything looks good !

Viktor
