We have to build two argument specs.
To populate the %parsed hash: Capture the arguments that the user has
passed in, as parsed by the Getopt::Long::GetOptions function. Aliases are converted
down to their short options. If a user passes ``--proximate'', Getopt::Long
converts that to ``-p'' and we store it as ``-p''.
To populate the @raw array: Capture the arguments raw, without having
been converted to their short options. If a user passes ``--proximate'',
we store it in @raw as ``--proximate''.
