# OSS-Fuzz requires a separate and self-contained binary for each fuzz target.
# To inject the fuzz target name in the finished binary, compile the fuzz
# executable with a "magic string" as the name of the fuzz target.
#
# An alternative to mocking the string in the finished binary would be to
# replace the string in the source code and re-invoke 'make'. This is slower,
# so use the hack.
