I have just send RFA_v3.
Note that following the above discussion, I have kept the word
'flag' for the cases where the code and/or documentation are
only related to flags, and have no other type of arguments.
The wording can be changed whenever other types of options
are added and/or when arg parsing is converted to the
generalized option parser

Thanks for the review comments and suggestions ...
