Is it possible to prevent setuptools from writing anything to stdout? For various inconvenient reasons our package must install silently - that means the installation process must not write to either stdout or stderr. Other than hacking distutils / setuptools to ensure that there's nothing which can write i've not yet been able to come up with a reliable means to control output.
