I'm afraid you are confusing the Genparse file of Genparse itself 
and the Genparse file of the program for which you want to write a 
command line parser.

I'm proposing to add the following line to the Genparse file for
Genparse:

i / internationalize	flag	"Put internationalization macro _() around text output."

If you invoke Genparse with the -i or --internationalize option
then it will add the internationalization macro _() around output
text like the help text in the usage() function. 

But of course you can still have a -i option in the Genparse file
for the program for which you want to generate a command line parser.

Do you understand or did I completely confuse you now? Do you know
about internationalization using the GNU gettext command?
