Command line and configuration file usage
In general, the program stores settings in a key/value map. These key=value parameters may be specified on the command line, or in a configuration file.
The command line is processed in-order. For example
$ ./picocoin value=1 list-settings value=2 list-settings
will execute the "list-settings" command twice, each with "value" setting initialized to a different parameter.
Similarly, you may read multiple configuration files into the settings map:
$ ./picocoin config=file1 config=file2 config=file3
