Unipath

----------------
* Fix unicode NameError on Python 3. (Appeared only on OSes with unicode
paths.)(Thanks to Hanlle Nicolas, Aaron Lelevier, Dmitry Dygalo.)
* Fix test on MacOSX: temp dir contains symlink. (wrightmx)
* Fix ``walk`` error in arg ``top_down``. (Gabriel Reyla == sesas)
* Fix ``isdir()`` issue on Windows. (Gabriel Reyla)
* Fix ``needs_update`` with string argument. (15)
* Change license to MIT. It's at least as free as the Python license but
doesn't contain irrelevant Python-specific language.

------------------
* Migrate repository to Git and Github. (https://github.com/mikeorr/Unipath)
* Supports Python 2.6, 2.7, 3.2, and 3.3. No longer suppots Python 2.5 or older.
* Python 3 compatibility. (Ricardo Duarte)
* Convert tests to py.test. (Ricardo Duarte)
* Delete old PEP 335 reference documentation. To recover, check out Git rev
7575cdf, directory "doc/reference".
* Undocument ``Path.copy_tree()``. It was never implemented.
* Fix Path.remove and Path.rmtree for symlinks. (Joel Rosdahl)

----------------------------------
* Delete spurious references to deleted ``unipath.platform`` package.

---------------------------
* Rename Path to AbstractPath, and FSPath to Path. FSPath remains as an
alias for backward compatibility.
* Allow integers in constructor.
* Path.mkdir() checks whether the directory exists first.
* Test suite now uses nose instead of unittest.
* "+" operator returns concatenated path rather than string.
* Bugfix in Path.rel_path_to().
* Thanks to Roman <mereandorgmail.com> for patches and suggestions.
* Delete Path.symlink(); use Path.write_link() instead -- note that the
arg is the desination rather than the source!
* Path.make_relative_link_to() is a shortcut for
``self.write_link(self.rel_path_to(dst))``.
* Delete the ``platform`` package. See the tests if you need non-native
path syntax.`

----------------------------------
* Initial release.
