[help-gengetopt] literature \n in default

[T o n g]

Hi, 

I want to show a literature \n in default, how can I do that? 

I tried with 

 option          "format"    F "format used for find -printf"  optional 
string typestr="fmt" default="%p\t%s\\n"

but get:

  -F, --format=fmt      format used for find -printf  (default=`%p\t%s\
                          ')

Please help. 

Thanks
