+r"""Installs files needed for tornado testing on windows.
+
+These instructions are compatible with the VMs provided by http://modern.ie.
+The bootstrapping script works on the WinXP/IE6 and Win8/IE10 configurations,
+although tornado's tests do not pass on XP.
+
+1) Install virtualbox guest additions (from the device menu in virtualbox)
+2) Set up a shared folder to the root of your tornado repo.  It must be a
+   read-write mount to use tox, although the tests can be run directly
+   in a read-only mount.  This will probably assign drive letter E:.
+3) Install Python 2.7 from python.org.
+4) Run this script by double-clicking it, or running
+   "c:\python27\python.exe bootstrap.py" in a shell.
+
+To run the tests by hand, cd to e:\ and run
+  c:\python27\python.exe -m tornado.test.runtests
+To run the tests with tox, cd to e:\maint\vm\windows and run
+  c:\python27\scripts\tox
+To run under cygwin (which must be installed separately), run
+  cd /cygdrive/e; python -m tornado.test.runtests
