     18  * This file is consumed by build/tools/fs_config and is used
     19  * for generating various files. Anything #define AID_<name>
     20  * becomes the mapping for getpwnam/getpwuid, etc. The <name>
     21  * field is lowercased.
     22  * For example:
     23  * #define AID_FOO_BAR 6666 becomes a friendly name of "foo_bar"
     24  *
     25  * The above holds true with the exception of:
     26  *   mediacodec
     27  *   mediaex
     28  *   mediadrm
     29  * Whose friendly names do not match the #define statements.
     30  *
     31  * Additionally, AID_OEM_RESERVED_START and AID_OEM_RESERVED_END
     32  * can be used to define reserved OEM ranges used for sanity checks
     33  * during the build process. The rules are, they must end with START/END
     34  * The proper convention is incrementing a number like so:
     35  * AID_OEM_RESERVED_START
     36  * AID_OEM_RESERVED_1_START
     37  * AID_OEM_RESERVED_2_START
     38  * ...
     39  * The same applies to the END.
     40  * They are not required to be in order, but must not overlap each other and
     41  * must define a START and END'ing range. START must be smaller than END.
