+# people with MSVC 2005 to open them.  Otherwise, MSVC 2005 simply refuses to
+# open projects created with 2008.  We run this as part of our release process.
+# If you obtained the code direct from version control and you want to use
+# MSVC 2005, you may have to run this manually.  (Hint:  Use Cygwin or MSYS.)
