I sumbitted a patch to the inetutils mailing list which shows how genparse
could be used for command line parsing of the ping command, see

http://lists.gnu.org/archive/html/bug-inetutils/2007-12/msg00006.html

This exercise hopefully gives you a better understanding of genparse, me 
a better understanding of argp and other people an opportunity to compare 
both tools :-)
