CDescriptor	Describes an option, its help text (usage) and how it should be parsed
COption	A parsed option from the command line together with its argument if it has one
CParser	Checks argument vectors for validity and parses them into data structures that are easier to work with
CStats	Determines the minimum lengths of the buffer and options arrays used for Parser
CUsageMsg	option::printUsage() formats the usage message with column alignment and line wrapping
