Member advgetopt::conf_file_setup::get_section_operator () const

The INI file support does not verify that a section name does not itself include more sub-sections. For example, the following would be three section names:

So in effect, the variable named var ends up in section a, sub-section b, and sub-sub-section c (or section a::b::c.) Before saving the results in the parameters, all section operators get transformed to the C++ scope (::) operator, which is why that operator used in any name ends up looking like a section separator.

The options are written from our map. This means the order will be alphabetical and not the order in which you defined the options. We are not looking into fixing this problem. That's just something you want to keep in mind.
