distribution) and other config values.
For the purposes of this module, the following nomenclature is used:
- "src-layout": a directory representing a Python project that contains a "src"
folder. Everything under the "src" folder is meant to be included in the
distribution when packaging the project. Example::
.
├── tox.ini
├── pyproject.toml
└── src/
└── mypkg/
├── __init__.py
├── mymodule.py
└── my_data_file.txt
- "flat-layout": a Python project that does not use "src-layout" but instead
have a directory under the project root for each package::
.
├── tox.ini
├── pyproject.toml
└── mypkg/
├── __init__.py
├── mymodule.py
└── my_data_file.txt
- "single-module": a project that contains a single Python script direct under
the project root (no directory used)::
.
├── tox.ini
├── pyproject.toml
└── mymodule.py

the finder implementation) found within directory 'where'.
'where' is the root directory which will be searched.
It should be supplied as a "cross-platform" (i.e. URL-style) path;
it will be converted to the appropriate local path syntax.
'exclude' is a sequence of names to exclude; '*' can be used
as a wildcard in the names.
When finding packages, 'foo.*' will exclude all subpackages of 'foo'
(but not 'foo' itself).
'include' is a sequence of names to include.
If it's specified, only the named items will be included.
If it's not specified, all found items will be included.
'include' can contain shell style wildcard patterns just like
'exclude'.

Normally auto-discovery would not be triggered if ``ext_modules`` are set
(this is done for backward compatibility with existing packages relying on
``setup.py`` or ``setup.cfg``). However, ``setuptools`` can call this function
to ignore given ``ext_modules`` and proceed with the auto-discovery if
``packages`` and ``py_modules`` are not given (e.g. when using pyproject.toml
metadata).

(or anything pointed by ``package_dir[""]``).
The "src-layout" is relatively safe for automatic discovery.
We assume that everything within is meant to be included in the
distribution.
If ``package_dir[""]`` is not given, but the ``src`` directory exists,
this function will set ``package_dir[""] = "src"``.

Since the ``flat-layout`` is more dangerous in terms of accidentally including
extra files/directories, this function is more conservative and will raise an
error if multiple packages or modules are found.
This assumes that multi-package dists are uncommon and refuse to support that
use case in order to be able to prevent unintended errors.

To avoid accidental inclusion of unwanted files or directories,
setuptools will not proceed with this build.
If you are trying to create a single distribution with multiple a�
on purpose, you should not rely on automatic discovery.
Instead, consider the following options:
1. set up custom discovery (`find` directive with `include` or `exclude`)
2. use a `src-layout`
3. explicitly set `py_modules` or `packages` with a list of names
To find more information, look for "package discovery" on setuptools docs.
