+ * BIOS Parser API usage:
+ *
+ * 1) bios_parser::getStrings gets all the attribute names and the preconfigured
+ *    strings used in representing the values of the attributes. This will be
+ *    used to populate the BIOS String table.
+ *
+ * 2) bios_enum::setupValueLookup (similar API for other supported BIOS
+ *    attribute types) has to be invoked to setup the lookup data structure for
+ *    all the attributes of that type. This API needs to be invoked before
+ *    invoking bios_enum::getValues and bios_enum::getAttrValue.
+ *
+ * 3) bios_enum::getValues is invoked to populate the BIOS attribute table for
+ *    BIOSEnumeration and BIOSEnumerationReadonly types.(similar API for other
+ *    BIOS attribute types)
+ *
+ * 4) bios_enum::getAttrValue will return the current values for the BIOS
+ *    enumeration attribute. If there is no D-Bus mapping for the attribute then
+ *    default value is returned.(similar API for other BIOS attribute types).
