//
// The test covers:
//
// - Combining different setting actions. Possible actions are: configuring a
// setting, negating a setting (adding "-no" prefix), and configuring/negating
// settings in a network section (adding "main." or "test." prefixes).
//
// - Combining settings from command line arguments and a config file.
//
// - Combining SoftSet and ForceSet calls.
//
// - Testing "main" and "testnet4" network values to make sure settings from network
// sections are applied and to check for mainnet-specific behaviors like
// inheriting settings from the default section.
//
// - Testing network-specific settings like "-wallet", that may be ignored
// outside a network section, and non-network specific settings like "-server"
// that aren't sensitive to the network.
