/*
Package xattr provides support for extended attributes on linux, darwin and freebsd.
Extended attributes are name:value pairs associated permanently with files and directories,
similar to the environment strings associated with a process.
An attribute may be defined or undefined. If it is defined, its value may be empty or non-empty.
More details you can find here: https://en.wikipedia.org/wiki/Extended_file_attributes
