copy __init__.py to build dir

This allows one to use something like

meson setup build && ninja -C build
PYTHONPATH=build make check

to check using the current build.

Without the __init__.py file in there, the system installation of cypari takes precedence.

I also added a (trivial) commit to print a message before starting autogen, which takes a long time.

@tobiasdiez does this look ok to you? My workflow is simpler with this.

Also, perhaps we should move cypari2 directory to src/cypari2 so it doesn't interfere.

As it is, running PYTHONPATH=build pytest but running PYTHONPATH=build python -m pytest gives an error (loads cypari2/__init__.py from ., because running this way adds an implicit . in the front of PYTHONPATH; the problem is that when cypari2/__init__.py is loaded from . the submodules are searched in the same path, but the *.so files are not there)

BTW, is there a way so that running pytest will run the tests from tests/rundoctests.py, so one doesn't need to run make check for that?

This is a good idea, and then you most likely don't need to copy the init file.

Yes, pytest can run doctests see https://docs.pytest.org/en/stable/how-to/doctest.html and https://github.com/lgpage/pytest-cython. But that likely requires a bit of tinkering. You can of course just run the rundoctests.py script manually, without make.

I think we still need __init__.py in the build directory (we need a directory

Sure, but this means I need to know to run rundoctests.py. Ideally, I just run pytest and all the tests are run, since this is the usual way to test python packages.
