Description:

KConfig provides an advanced configuration system. It is made of two
parts: KConfigCore and KConfigGui.

KConfigCore provides access to the configuration files themselves. It
features:

- Code generation: describe your configuration in an XML file, and use
`kconfig_compiler to generate classes that read and write
configuration entries.
- Cascading configuration files (global settings overridden by local
settings).
- Optional shell expansion support (see [docs/options.md](@ref
options)).
- The ability to lock down configuration options (see
[docs/options.md](@ref options)).

KConfigGui provides a way to hook widgets to the configuration so that
they are automatically initialized from the configuration and
automatically propagate their changes to their respective
configuration files.
