 xattr is a Python wrapper for extended filesystem attributes.
 
+xattr also ships with an `xattr` command line tool for viewing and
+editing extended filesystem attributes. On platforms that support or
+ship with the attr package, you may prefer to use the `getfattr`
+and `setfattr` command line tools from the attr package.
+
 Extended attributes extend the basic attributes of files and directories
 in the file system.  They are stored as name:data pairs associated with
 file system objects (files, directories, symlinks, etc).
