Proper way to put comments in build events command line?

What's the proper way to put comments into the pre/post build event command l开发者_JS百科ine?

Use REM: http://www.robvanderwoude.com/comments.php

An example:

REM signtool sign /a $(TargetPath)
xcopy /Y "$(TargetPath)" "C:\Deploy\$(TargetFileName)"

You can also use double colons ::

:: My comments
xcopy /Y "$(TargetPath)" "C:\Deploy\$(TargetFileName)"

I prefer these to the REM keyword in command line (and bat files).
