[bug-inetutils] Re: Command line parsing of ping with genparse

[Alfred M. Szmidt]

   Attached is a patch which shows how genparse could be used for
   command line parsing of the ping command of the inetutils.

My memory failed me, ping has been already been argpified. I was
really refering to ifconfig, which has very hairy parsing semantics
involving getopt children.

I doubt we will change any time soon from argp, argp is a standard
part of any GNU system variant, it also does somethings that genparse
does not, most notably leaving --help and --version entierly up to
argp and not to the maintainer (while still giving the maintainer
enough room to customise the output, see libinetutils/libinetutils.h).
With genparse (from the little I saw) you must manually handle all
arguments that you wish to parse, building up a list of if-clauses
that handle each option.
