# This package provides only the SDK files for Intel Media Server Studio.
# The proper installation requires a specific (older) Linux kernel version,
# kernel patches and other system modifications. For the sake of the system,
# this package will not touch the kernel or system libraries. Only the SDK
# files will be provided.
