FYI man2 is for man 2 section, man 3 is for man 3 section:

doc/conf.py

    'man2': ('https://man7.org/linux/man-pages/man2/%s.2.html', '%s(2)'),
    'man3': ('https://man7.org/linux/man-pages/man3/%s.3.html', '%s(3)'),

i.e. :man2:`clone` leads to man clone(2)
https://man7.org/linux/man-pages/man2/clone.2.html

which describes both syscalls:
clone, __clone2, clone3 - create a child process

But sure man clone3(2) links also works (the same page as man clone(2)).
https://man7.org/linux/man-pages/man2/clone3.2.html

FYI (if you have time) this should generate doc

$ cd doc; make setup && make

which is under ./html/users/test_catalog.html
and online:
https://linux-test-project.readthedocs.io/en/latest/users/test_catalog.html

> I understand the other comments and will implement them, nit or not :).

Thank you!

Kind regards,
Petr
