# DEVELOPMENT NOTE:
#
# While developing the solution, you can override the settings below using a temporary/secondary  file,
# so you don't need to modify the default configuration stored here.
#
# To do so, create an INI file, anywhere in your system, preferably outside the project to avoid
# the risk of checking the file into the repository. Name the file anything you like, e.g.
# "my-settings.ini", "simulation-dev-settings.ini" etc.
#
# Add to the file only the settings you need to override, i.e. you don't need to enter all the settings.
# Just make sure that each setting is under the right section, e.g. "[DeviceSimulationService:Logging]"
#
# Then, create an environment variable with name "PCS_DEV_APPSETTINGS" and put the complete file path in it.
# For instance "d:\temp\my_settings.ini" or "/tmp/dev-settings.ini".
