+/* redisassert.h -- Drop in replacemnet assert.h that prints the stack trace
+ *                  in the Redis logs.
+ *
+ * This file should be included instead of "assert.h" inside libraries used by
+ * Redis that are using assertions, so instead of Redis disappearing with
+ * SIGABORT, we get the details and stack trace inside the log file.
