            !!
      
                    ********************************************************************************
                    ############################
                    # Package would be ignored #
                    ############################
                    Python recognizes 'libcst.tests.pyre' as an importable package[^1],
                    but it is absent from setuptools' `packages` configuration.
      
                    This leads to an ambiguous overall configuration. If you want to distribute this
                    package, please make sure that 'libcst.tests.pyre' is explicitly added
                    to the `packages` configuration field.
      
                    Alternatively, you can also rely on setuptools' discovery methods
                    (for example by using `find_namespace_packages(...)`/`find_namespace:`
                    instead of `find_packages(...)`/`find:`).
      
                    You can read more about "package discovery" on setuptools documentation page:
      
                    - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html
      
                    If you don't want 'libcst.tests.pyre' to be distributed and are
                    already explicitly excluding 'libcst.tests.pyre' via
                    `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
                    you can try to use `exclude_package_data`, or `include-package-data=False` in
                    combination with a more fine grained `package-data` configuration.
      
                    You can read more about "package data files" on setuptools documentation page:
      
                    - https://setuptools.pypa.io/en/latest/userguide/datafiles.html
      
      
                    [^1]: For Python, any directory (with suitable naming) can be imported,
                          even if it does not contain any `.py` files.
                          On the other hand, currently there is no concept of package data
                          directory, all directories are treated like packages.
