# These leveldb *_test.cc files all define their own identical main function which

# really difficult to deal with in our setup, so we glob them into one binary
# called leveldb_tests. To do this we need to give each file a different name
# for its main symbol which we'll ignore. We do this with the magic and horror
# of a GN template to generate distinct defines for each file.
