-# The unnecessary files has been removed to make the library small. It only contains include and lib now.
+# following TensorRT.tar.gz is not the default official one, we do two miny changes:
+# 1. Remove the unnecessary files to make the library small. TensorRT.tar.gz only contains include and lib now,
+#    and its size is only one-third of the official one.
+# 2. Manually add ~IPluginFactory() in IPluginFactory class of NvInfer.h, otherwise, it couldn't work in paddle.
+#    See https://github.com/PaddlePaddle/Paddle/issues/10129 for details.
