I started a wiki page for new_command and think that everything is ok by now.

Can you point me on how to make the community aware so they can also test?

May I add these entries from my .gitignore into yours?

*.egg-info/
*.so
.venv/

Hi Pedro, couple of high-level things first:

1. For your PRs, can you make a description of a summary/what the PR is trying to accomplish?
2. Can I ask why you're removing helping.py in tests?
3. Changes to the .gitignore would be better suited as a separate PR.

1. I added support to the quiet=1 option from PyMOL CLI. Also better error messages explaining the reason of the calling error (in case the user made a calling error). Initially I tried to make multi-line error messages (like Tornado exceptions if I recall correctly), but they were becoming ugly and not user-friendly, so I gave up.
2. I removed tests/helping.py by mistake!

And I don't know why the tests are failing, in my machine they're ok.
