from the compilation error, it would seem kingpin.Flag...ExistingFile()
returns a *string, not a string.
so these lines:
fmt.Printf("%v, %s, %T\n", config, config, config)
cfg, err := ini.Load(config)
should be replaced with:
fmt.Printf("%v, %s, %T\n", *config, *config, *config)
cfg, err := ini.Load(*config)
hth,
