[PATCH v2 04/15] python: add directory structure README.rst files

From: John Snow
Subject: [PATCH v2 04/15] python: add directory structure README.rst files
Date: Wed, 14 Oct 2020 10:29:46 -0400

Add short readmes to python/, python/qemu/, and python/qemu/core that
explain the directory hierarchy. These readmes are visible when browsing
the source on e.g. gitlab/github and are designed to help new
developers/users quickly make sense of the source tree.

They are not designed for inclusion in a published manual.

+QEMU Python Tooling
+This directory houses Python tooling used by the QEMU project to build,
+configure, and test QEMU. It is organized by namespace (``qemu``), and
+then by package (``qemu/core``).
+``setup.py`` is used by ``pip`` to install this tooling to the current
+environment. You will generally invoke it by doing one of the following:
+1. ``pip3 install .`` will install these packages to your current
+   environment. If you are inside a virtual environment, they will
+   install there. If you are not, it will attempt to install to the
+   global environment, which is not recommended.
+2. ``pip3 install --user .`` will install these packages to your user's
+   local python packages. If you are inside of a virtual environment,
+   this will fail.
+If you amend the ``-e`` argument, pip will install in "editable" mode;
+which installs a version of the package that uses symlinks to these
+files, such that the package always reflects the latest version in your
+git tree.
+See `Installing packages using pip and virtual environments
+for more information.

+QEMU Python Namespace

+namespace package <<https://www.python.org/dev/peps/pep-0420/>`_.
+Each directory below is assumed to be an installable Python package that
+is available under the ``qemu.<package>`` namespace.

+qemu.core Package
+This package provides core utilities used for testing and debugging
+QEMU. It is used by the iotests, vm tests, and several other utilities
+in the ./scripts directory. It is not a fully-fledged SDK and it is
+subject to change at any time.
+See the documentation in ``__init__.py`` for more information.
