The point is, you would like to specify the options once, and use this
single specification for all option sources - instead of redundantly having
to specify that there is a 'verbosity' option that takes a value of 'int'
and has a default of 'whatever', and do this once (and with different
syntax) for each source - config files, command line, etc.
