/*
 * 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.
