+Helps mimic a *nix environment on Windows with as little work as possible.
+
+The script:
+* Provides standard ipython operation for msysgit
+* Provides standard nosetests behavior for msysgit
+* Installs nano and makes it accessible from msysgit
+
+To use:
+
+1. Install Anaconda CE Python distribution
+   http://continuum.io/anacondace.html
+2. Install msysgit
+   http://code.google.com/p/msysgit/downloads/list?q=full+installer+official+git
+3. Run swc_windows_installer.py
+   You should be able to simply double click the file in Windows
