Object-oriented alternative to os/os.path/shutil
Unipath is an object-oriented approach to file/pathname manipulations and filesystem calls, an alternative to ``os.path.*``, ``shutil.*``, and some ``os.*`` functions. It's based on Orendorff's path.py but has been refactored to make application code more concise, by focusing on what the programmer wants to do rather than on low-level operations exactly like the C library.
