+# Host-side tests for the Wi-Fi crypto and the WPA supplicant.
+#
+# These compile the real kernel sources (Libraries/Crypto.cpp and
+# Drivers/Net/Wifi/Wpa.cpp) for the host against the small shim in shim/, so
+# what is exercised is the code that ships, not a copy of it.
+#
+# Requires: g++ with C++20, python3 with the `cryptography` package.
