Its the completely wrong way if you want to open an arbitrary ini-style
file. This includes .desktop files as well as project files for some apps
(for example kdevelop uses kconfig-formatted files for both its project
info and project templates). 

Anyway, the right replacement to use instead of KSharedConfig::openConfig
is the KConfig constructor taking a file and open-flags.


You will outgrow your usefulness.
