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).
- The ability to lock down configuration options (see docs/options.md).
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.
