Pathlib offers a set of classes to handle filesystem paths. it offers the following advantages over using string objects:

* no more cumbersome use of os and os.path functions. everything
can be done easily through operators, attribute accesses, and method calls.
* embodies the semantics of different path types. for example,
comparing windows paths ignores casing.
* well-defined semantics, eliminating any warts or ambiguities
(forward vs. backward slashes, etc.).
this package includes the documentation in html and txt format.
