# Input selectors:
#	isSystemServer (boolean)
#	isOwner (boolean)
#	user (string)
#	seinfo (string)
#	name (string)
#	path (string)
#	isPrivApp (boolean)
# isSystemServer=true can only be used once.
# An unspecified isSystemServer defaults to false.
# isOwner=true will only match for the owner/primary user.
# isOwner=false will only match for secondary users.
# If unspecified, the entry can match either case.
# An unspecified string selector will match any value.
# A user string selector that ends in * will perform a prefix match.
# user=_app will match any regular app UID.
# user=_isolated will match any isolated service UID.
# isPrivApp=true will only match for applications preinstalled in
#       /system/priv-app.
# All specified input selectors in an entry must match (i.e. logical AND).
# Matching is case-insensitive.
#
# Precedence rules:
# 	  (1) isSystemServer=true before isSystemServer=false.
# 	  (2) Specified isOwner= before unspecified isOwner= boolean.
#	  (3) Specified user= string before unspecified user= string.
#	  (4) Fixed user= string before user= prefix (i.e. ending in *).
#	  (5) Longer user= prefix before shorter user= prefix.
#	  (6) Specified seinfo= string before unspecified seinfo= string.
#	      ':' character is reserved and may not be used.
#	  (7) Specified name= string before unspecified name= string.
#	  (8) Specified path= string before unspecified path= string.
# 	  (9) Specified isPrivApp= before unspecified isPrivApp= boolean.
#
# Outputs:
#	domain (string)
#	type (string)
#	levelFrom (string; one of none, all, app, or user)
#	level (string)
# Only entries that specify domain= will be used for app process labeling.
# Only entries that specify type= will be used for app directory labeling.
# levelFrom=user is only supported for _app or _isolated UIDs.
# levelFrom=app or levelFrom=all is only supported for _app UIDs.
# level may be used to specify a fixed level for any UID.
#
#
# Neverallow Assertions
# Additional compile time assertion checks can be added as well. The assertion
# rules are lines beginning with the keyword neverallow. Full support for PCRE
# regular expressions exists on all input and output selectors. Neverallow
# rules are never output to the built seapp_contexts file. Like all keywords,
# neverallows are case-insensitive. A neverallow is asserted when all key value
# inputs are matched on a key value rule line.
#

# only the system server can be in system_server domain
