+///
+/// Absolutize target path if relative.
+/// For example:
+///
+/// ```rust
+/// assert_eq!(absolutize(&Path::new("/home/omar"), &Path::new("readme.txt")).as_path(), Path::new("/home/omar/readme.txt"));
+/// assert_eq!(absolutize(&Path::new("/home/omar"), &Path::new("/tmp/readme.txt")).as_path(), Path::new("/tmp/readme.txt"));
+/// ```
