Configuration reference

Settings live in config.toml in the data directory (~/.wats by default). Edit them with wats config set <key> <value>, wats config get <key>, wats config unset <key> or wats config edit. Command-line flags and WATS_* variables, where they exist (wats --help), take precedence over the file.
