On Unix systems, it's common for programs to read their input from stdin, and write their output to stdout. Messages should be written to stderr, where they won't corrupt a program's output, and where they can be seen by the user even if the output is being redirected. This is mostly a problem when XGBoost is being used from Python or from another program.
