-# wireguard-go depends on maybenot-ffi
+# The app does not depend on maybenot-ffi itself, but adds it as a dependency to expose FFI symbols to wireguard-go. 
+# This is done, instead of using the makefile in wireguard-go to build maybenot-ffi into its archive, to prevent
+# name clashes induced by link-time optimization.
+# NOTE: the version of maybenot-ffi below must be the same as the version checked into the wireguard-go submodule
