+# ******************* Comments from raiagent repo: *************************
+#
+# All Kivy dependencies (except those enabling "USE_*" environment variables
+# exported by the python_compile() phase) are runtime-only. Note that:
+# * Cython is mandatory, despite "setup.py" containing a "can_use_cython" bool.
+# * Pygame and SDL2 are mutually incompatible, as the former assumes SDL1.
+# * "setup.cfg" lists numerous *OPTIONAL RUNTIME* dependencies as *MANDATORY
+#   BUILD-TIME* dependencies, including:
+#     install_requires =
+#         Kivy-Garden>=0.1.4
+#         docutils
+#         pygments
+#
+# Technically, we *COULD* omit those dependencies below. Why? Because Portage's
+# PEP 517-compliant integration with "setuptools" ignores "setup.cfg".
+# Pragmatically, doing so would erroneously attempt to install one or more of
+# those dependencies when a downstream user editably installs their Kivy app:
+#     # This will attempt to install those dependencies.
+#     $ sudo python3.10 -m pip install -e .
+#
+# Ergo, we defer to Kivy's erroneous "setup.cfg" and list those dependencies.
+# When Kivy removes those dependencies from "setup.cfg":
+# * The "highlight" USE flag will still require an optional runtime dependency
+#   on "pygments": e.g.,
+#       highlight? ( dev-python/pygments[${PYTHON_USEDEP}] )
+# * The "rst" USE flag will still require an optional runtime dependency on
+#   "docutils": e.g.,
+#       rst? ( dev-python/docutils[${PYTHON_USEDEP}] )

+	# * The "KIVY_BUILD_EXAMPLES" environment variable (and corresponding

+	#   should have just packaged "Kivy-examples" as a real honest project.
+	# * The "KIVY_SPLIT_EXAMPLES" environment variable installs examples to an
+	#   unversioned "/usr/share/kivy-examples" directory, which violates Gentoo
