+// Normally fuzzers are run by libFuzzer, which executes the entry function
+// LLVMFuzzerTestOneInput() with many different inputs, but it can be useful to
+// run them with just a single input to check a particular problem found during
+// fuzzing. To do this, link the fuzzer code with this file and run it with the
+// file name containing the test data. E.g. an example use:
+//
+//  $ g++ -g -fsanitize=undefined tests/fuzz/{zip,runner}.cpp `wx-config --cxxflags --libs base`
+//  $ ./a.out testcase-found-by-libfuzzer
