  Production:
    dc [options] => docker-compose [options]
    dcup => Starts a Docker container in detached mode
    dcdown => Destroys the started Docker container
    dcrestart => Destroys and creates a new Docker container
    dcx <subsystem> [command] => docker-compose exec <subsystem> [command]
    
  setversion <version number> => Sets the VERSION_TAG environment variable
  setlatest => Sets the VERSION_TAG environment variable to the latest version available on GitHub
  
  The setlatest command requires curl and python to be installed.

  Development:
    devmode => Sets the COMPOSE_PROJECT_NAME environment variable.
    dcd [options] => docker-compose -f docker-compose.dev.yml [options]
    dcdup => Builds the development Docker container using the docker-compose.dev.yml file
    dcddown => Destroys the development Docker container
    dcdrestart => Destroys and builds a new development Docker container
    dcdx <subsystem> [command] => docker-compose -f docker-compose.dev.yml exec <subsystem> [command]
    dcdsetup => Runs the setup commands within the development Docker container
    dcdbuild => Rebuilds the development Docker container without using the cache
    dcdresetall => Deletes all Docker volumes of the development environment
    setdevref <ref> => Sets the developer target reference. Can be a branch, tag, or specific commit hash.
