How do I resolve '@echo' is not a recognized command

Question

I've implemented Scott Hanselman's method for keeping up with a dev/qa/prod version of web.config: http://www.hanselman.com/blog/CommentView.aspx?guid=93bfa4b3-44cd-4681-b70e-f4a2b0386466

For some reason when I compile my project I get this error message in my output window.
Any ideas?

------ Build started: Project: ABC.Flims.Web, Configuration: Development Any CPU ------
"C:\Projects\ballyhoo-trunk\src\ABC.Flims.Web\scripts/copyifnewer.bat" "C:\Projects\ballyhoo-trunk\src\ABC.Flims.Web\web.config.Development" "C:\Projects\ballyhoo-trunk\src\ABC.Flims.Web\web.config"
'@echo' is not recognized as an internal or external command,
operable program or batch file.  

Here is the script file:

@echo off
echo Comparing two files: %1 with %2

if not exist %1 goto File1NotFound
if not exist %2 goto File2NotFound

fc %1 %2 
if %ERRORLEVEL%==0 GOTO NoCopy

echo Files are not the same.  Copying %1 over %2
copy %1 %2 /y & goto END

:NoCopy
echo Files are the same.  Did nothing
goto END

:File1NotFound
echo %1 not found.
goto END

:File2NotFound
copy %1 %2 /y
goto END

:END
echo Done.

The file is probably Unicode encoded and has a Byte Order Mark (BOM) at the start that is throwing off the batch processor.

Save it as an ASCII file and you should be OK. You can do this in notepad - select Save As... from the File menu and ensure that the Encoding dropdown is set to ANSI.
