# An overly complicated SIP config checker

# This is a technically interesting implementation because it does not rely on csrutil
# Instead it queries the kernel directly for the current configuration status
# This means, for example, in environments where SIP has been disabled and csrutil has
# been removed or modified (say, with DYLD_LIBRARY_PATH), as long as python can run you
# can still check status

# Additionally, checking the nvram csr-active-config setting isn't accurate now with
# 10.12.2+, since running "sudo csrutil clear" deletes the variable until reboot,

# The marketing information embedded in the ServerInformation.framework is not the same as what
