 This project uses Travis CI to perform tests on linux (Ubuntu 12.04 LTS "Precise Pangolin") and
 Appveyor (Windows Server 2012 R2, similar to Windows 8) to perform continuous integration.
 
-On linux, Python 3.3 and 3.4 with PySide, PyQt4, and PyQt5 are tested. On windows, Python 3.4 with
-PySide, PyQt4 and PyQt5 are tested, but Python 3.3 is only tested with PySide since binary installers
-for PyQt are not provided for Python 3.3 (at least not the newest versions of PyQt), and compiling 
-from source probably isn't worth it.
-
-Python 3.5 is now tested on linux with PyQt4 and PyQt5.
