/*

 * This file is consumed by build/tools/fs_config and is used

 * for generating various files. Anything #define AID_<name>

 * becomes the mapping for getpwnam/getpwuid, etc. The <name>

 * field is lowercased.

 * For example:

 * #define AID_FOO_BAR 6666 becomes a friendly name of "foo_bar"

 *

 * The above holds true with the exception of:

 *   mediacodec

 *   mediaex

 *   mediadrm

 * Whose friendly names do not match the #define statements.

 *

 * Additionally, AID_OEM_RESERVED_START and AID_OEM_RESERVED_END

 * can be used to define reserved OEM ranges used for sanity checks

 * during the build process. The rules are, they must end with START/END

 * The proper convention is incrementing a number like so:

 * AID_OEM_RESERVED_START

 * AID_OEM_RESERVED_1_START

 * AID_OEM_RESERVED_2_START

 * ...

 * The same applies to the END.

 * They are not required to be in order, but must not overlap each other and

 * must define a START and END'ing range. START must be smaller than END.
