Mantis can be either configured using config files and JVM parameters.
Config files
Several files are provided in order to change Mantis configuration. All of them can be found under relase conf folder.
Each file allows to configure a different aspect of the client. The entry point one is `mantis.conf. To override a setting, go to a specific file, uncomment a setting and provide a value.
