reftool is useful for exploring the results of those unit tests that leave
traces in the form .out and .ref files.  It allows you to update the ref
files, view diffs between the .outs, and view the associated test files.

To use it you must have 2 modules installed:

  - The 'oath' user interface.  Available from
    http://smallcultfollowing.com/code/oath/. (Requires curses, which
    you hopefully have already).

  - The 'path' module for dealing with file name paths.  Available
    from http://www.jorendorff.com/articles/python/path/.

To begin, execute "python reftool/reftool.py" from the parent directory
of the one this readme is in (i.e., pynto/tests) after running the unit
tests.

Enjoy!
