this is an experimental command to use external data as input arguments.
A series of data is used (only CSV is implemented so far), and it is used to fill argument of a command according to a sequence.
The sequence is given using input arguments, with types corresponding to the data found (short option, long option, stdin).
e.g. if a CSV file has row with 3 columns, we can say that column 1 is subject (long option), column 2 is body (stdin), and column 3 is language (short option -l).
A filter can be used after each option type, to transform read value.
Finally a static part is used to have the main command and non dynamic arguments to use.
