+# When compiled by Nuitka into a standalone binary however, data files added
+# via --include-data-dir/--include-data-files (e.g. "lib=lib") are placed
+# relative to the *distribution* directory (next to the produced .exe), not
+# relative to this module's own (nested) package directory. Using
+# os.path.dirname(__file__) in that case points at "<dist>/freedata_server"
+# while the actual DLL ends up at "<dist>/lib/codec2/libcodec2.dll" - a
+# sibling directory, not a child - so the glob below never finds it.
+#
+# Nuitka exposes the correct directory via the compiled-only global
+# `__compiled__.containing_dir`, which always points at the distribution
+# directory regardless of platform or nesting. See:
