+Installing Visual Compiler v9 (for Python 2.7)
+----------------------------------------------
+
+This compiler, while the standard one for Python 2.7, is depricated. Microsoft
has
+made it available as the `Microsoft Visual C++ Compiler for Python 2.7`_ (the
link
+was checked in Nov 2016). Note that the compiler suite will be installed in
+``C:\Users\<user name>\AppData\Local\Programs\Common\Microsoft\Visual C++ for
Python``.
+Using a current version of ``setuptools`` will be able to find it there. For
+Windows 10, you must right-click the download, and under ``Properties`` ->
+``Compatibility`` mark it as ``Run run this program in comatibility mode for``
+``Previous version...``. Also, you must download and install the ``.Net
Framework 3.5``,
+otherwise ``mt.exe`` will silently fail. Installation will begin automatically
+by running the mt.exe command by hand from a DOS window (that is how the author
+discovered the problem).
