[Help-gengetopt] Help about multiple options.

[Hakan Bayındır]

Hello,

I'm developing an application for some time and its backed by an elaborate 
logging library, which supports multiple levels of verbose output. 

To implement this feature in gengetopt, I've used the following line:

option "verbose" v "Enable verbose output." typestr="level" int default="0" 
optional

This allows me to pass "-v 2" or "--verbose 2" style options to set desired 
verbosity, however I want to be able to pass "-v", "-vv" and similar styled 
flags for verbosity selection. I've dug version 2.23 documentation but failed 
to find/understand if it's possible, and how it's done.

Any help will be greatly appreciated,

Thanks in advance,

Hakan
