 # This is joint configuration file for both the server and the data probes. Note that
 # server and probe configuration can be placed into separate files - each file containing only
 # 'nlpcraft.server' or 'nlpcraft.probe' sub-sections.
 #
 # You can also provide configuration properties or override the default ones via environment variables.
 # To use environment variables override:
 # 1. Set probe or server JVM system property -Dconfig.override_with_env_vars=true
 # 2. For each configuration 'x.y.z' set the environment variable CONFIG_FORCE_x_y_z=some_value
 #
 # Examples of environment variables:
 #   -- Overrides 'nlpcraft.sever.host' configuration property.
 #   CONFIG_FORCE_nlpcraft_server_rest_host="localhost"
 #
 #   -- Overrides 'nlpcraft.sever.models' configuration property.
 #   CONFIG_FORCE_nlpcraft_server_models="com.models.MyModel"
