4.Configuration
=============

The behaviour of **CGRateS** can be externally influenced by following means:

- Engine configuration files, usually located at */etc/cgrates/*. There can be one or multiple file/folder hierarchies behind configuration folder with support for automatic includes. The folders/files will be imported in alphabetical order into final configuration object.
- Tariff Plans: set of files used to import various data used in CGRateS subsystems (eg: Rating, Accounting, LCR, DerivedCharging, etc).
- RPC APIs: set of JSON/GOB encoded APIs remotely available for various operational/administrative tasks.
