I've used Windows specific functions for reading/writing configuration (INI)

library available that is recommended.
I searched the boost libs for something and there are libs of course that can
achieve this with some programming, but I'd like to know if there is something
(boost or other library) with specific functionality to handle reading/writing
INI files. Example:
[General]
Language=Français
[Strings]
String00001=Version
String00002=Etes vous sûr ?
String00003=Voulez-vous continuer ?
When I want to do something like this, I use Lua. Eg.
conf.lua
conf = {
general = {
language='Français',
},
strings = {
string00001='Version',
string00002='Etes vous sûr ?',
string00003='Voulez-vous continuer ?',
},
}

Of course, you can get more clever with the organization of your data
and the iteration method than I have here (see lua_next over indexed
tables (lists) instead of string00001, ...2, ...3, etc.) but you get
the idea.
