/* The commands from the SDK are defined with `cobra` and configured with the `viper` package. This takes place in the `InterceptConfigsPreRunHandler` function. Since the `viper` package is used for configuration the precedence is dictated by that package. That is 1. Command line switches 2. Environment variables 3. Files from configuration values 4. Default values The global configuration instance exposed by the `viper` package is not used by Cosmos SDK in this function. A new instance of `viper.Viper` is created and the following is performed. The environmental variable prefix is set to the current program name. Environmental variables consider the underscore to be equivalent to the `.` or `-` character. This means that an configuration value called `rpc.laddr` would be read from an environmental variable called `MYTOOL_RPC_LADDR` if the current program name is `mytool`. Running the `InterceptConfigsPreRunHandler` also reads `app.toml` and `config.toml` from the home directory under the `config` directory. If `config.toml` or `app.toml` do not exist then those files are created and populated with default values. */ package server
