Hi

this version

http://rap.dsi.unifi.it/~bettini/gengetopt-2.22b.tar.gz

should implement also this feature: it saves (in a comment) also the corresponding actual value for options with values (and enums)

I'd be ready with 2.22 release by next week

hope to hear from you soon

option = "ele" # element

The point here is that application may alter the user-supplied
arguments, thus when dumping the actual config it may worth knowing
what the application really thinks abou the options' actual value.

yes that'd be helpful; of course, this makes sense only for options with values right?

As far as I see, yes. (Actually I'd like to use only for enums ;) and strings.)

well it should be "quite" simple:

- first of all, I assume this will be done only for options with values
- in this case, output the element of the array holding the string values for an option with values (using the correct index)

well, actually I
I took a look at generated source and I figured out I would have to modify 
write_into_file() function.  I don't see how it would be the best though...

Notice that I'd avoid print numeric values since their conversion into

Oh, I thought _orig always contains the original string representation from 
argv[]. By the way, it doesn't matter me right now as I said before I want to 
use it for string option in first place.
