+ soft Expand soft links into new objects\n\n\
+ ext Expand external links into new objects\n\n\
+ ref Copy references and any referenced objects, i.e., objects\n\
+ that the references point to.\n\
+ Referenced objects are copied in addition to the objects\n\
+ specified on the command line and reference datasets are\n\
+ populated with correct reference values. Copies of referenced\n\
+ datasets outside the copy range specified on the command line\n\
+ will normally have a different name from the original.\n\
+ (Default:Without this option, reference value(s) in any\n\
+ reference datasets are set to NULL and referenced objects are\n\
+ not copied unless they are otherwise within the copy range\n\
+ specified on the command line.)\n\n\
+ noattr Copy object without copying attributes\n\n\
allflags Switches all flags from the default to the non-default setting\n\n\
