      1 // Package ini implements parsing of the AWS shared config file.
      2 //
      3 //	Example:
      4 //	sections, err := ini.OpenFile("/path/to/file")
      5 //	if err != nil {
      6 //		panic(err)
      7 //	}
      8 //
      9 //	profile := "foo"
     10 //	section, ok := sections.GetSection(profile)
     11 //	if !ok {
     12 //		fmt.Printf("section %q could not be found", profile)
     13 //	}
