[libvirt] [libvirt-designer][PATCH 3/4] examples: Create an example of usage program

[Christophe Fergeau]

Hey,

I haven't looked at the patch in depth, just a few comments:

glib has its own commandline parser

I'm not saying you have to use it, I'm merely mentioning it in case you
prefer something different from getopt.

You can also use g_path_get_basename

libvirt-glib has gvir_connection_get_capabilities, I'm not sure about
virConnectOpenAuth. With that said, I guess not using libvirt-gobject is
done on purpose as libvirt-designer is not depending on it, right?
