-# sepolicy is now divided into multiple portions:
-# public - policy exported on which non-platform policy developers may write
-#   additional policy.  types and attributes are versioned and included in
-#   delivered non-platform policy, which is to be combined with platform policy.
-# private - platform-only policy required for platform functionality but which
-#  is not exported to vendor policy developers and as such may not be assumed
-#  to exist.
-# vendor - vendor-only policy required for vendor functionality. This policy can
-#  reference the public policy but cannot reference the private policy. This
-#  policy is for components which are produced from the core/non-vendor tree and
-#  placed into a vendor partition.
-# mapping - This contains policy statements which map the attributes
-#  exposed in the public policy of previous versions to the concrete types used
-#  in this policy to ensure that policy targeting attributes from public
-#  policy from an older platform version continues to work.
-
-# build process for device:
-# 1) convert policies to CIL:
-#    - private + public platform policy to CIL
-#    - mapping file to CIL (should already be in CIL form)
-#    - non-platform public policy to CIL
-#    - non-platform public + private policy to CIL
-# 2) attributize policy
-#    - run script which takes non-platform public and non-platform combined
-#      private + public policy and produces attributized and versioned
-#      non-platform policy
-# 3) combine policy files
-#    - combine mapping, platform and non-platform policy.
-#    - compile output binary policy file
