17 This routine will load a named configuration file and parse the text as
18 a hierarchically valued option. The option descriptor created from an
19 option definition file is not used via this interface. The returned
20 value is "named" with the input file name and is of type
21 "OPARG_TYPE_HIERARCHY". It may be used in calls to optionGetValue(),
22 optionNextValue() and optionUnloadNested().
