+# This script looks for instances of C comparison operators as macro arguments,
+# and replaces them with our OP_* equivalents.
+#
+# Some macros that take operators are our tt_int_op() testing macro, and the
+# standard timercmp() macro.  Coccinelle can't handle their syntax, however,
+# unless we give them their operators as a macro too.
