Ah, now I see. Please scroll to the end of the document

after this section

http://www.litwindow.com/lwl/doc/html/comparison_10x.html#complex_rules

"Preparing to use the Lit Window Library".

The cfg object accesses the Settings object or any other object through 
a 'data abstraction layer', a type of reflection mechanism. The 
"Preparing to use..." section shows you what you have to do for the 
Settings class definition so that the operator >> knows what to do.

A 'data adapter' is basically a map<string, accessor>, mapping member 
variables of a class to get/set functions.

No, it does not parse header files. You have to include a small 
declaration for the data adapter. See the "Preparing..." text part of 
the document above.

Thanks a lot, I am looking forward to your comments.
