 /**
-  @brief Mac policy module data
-
-  This structure specifies module data that is passed in to the
-  TrustedBSD MAC policy module by the kernel module loader.  The
-  data is made of up key/value pairs where the key is always a
-  string and the value is a string, binary data or array.  An array
-  may be a list of values (actually a similar set of key/value pairs,
-  but in this case the keys are always null), and may also consist of
-  a set of dictionaries, which in turn are made up of a list of key/value
-  pairs.
-
-  Module data may be specified in the MAC policy module's
-  Info.plist file as part of the OSModuleData dictionary.
-
-  E.g.
-
-  <key>OSModuleData</key>
-  <dict>
-       <key>foo</key>
-       <string>bar</string>
-       <key>Beers</key>
