+# THIRD_PARTY_SOURCES is a list of patterns compatible with the
+# $(filter) and $(filter-out) family of functions. They specify source
+# files which are taken from some third-party source where we want to be
+# less strict about issues such as coding style so we don't diverge from
+# upstream unnecessarily (making merging in future changes easier).
