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//	}
