+REM This batch file is meant to facilitate regenerating prebuilt binaries for 
+REM the Windows tools.
+REM You MUST run it from a Visual Studio xxxx Command Prompt.  To do this,
+REM navigate to:
+REM 
+REM    Start->Programs->Microsoft Visual Studio XXXX->Tools->
+REM                        Visual Studio Command Prompt
+REM
+REM Then run this batch file.  It performs an SVN update, edits the
+REM README.binaries file to contain
+REM the revision number, and builds the tools.  You must run 'svn commit' to
+REM commit the pending edits to the repository.
