The idea is to make a canonical representation of any path, taking into account . and .. and unicode-prefix on Windows. The use case is in a shell you have a current-directory and you can do crazy commands like ``cd ../foo/bar/baz/../.././././`` and get the canonical/shortened directory name. You can also use this word to compare if two paths are the same.  |
