Expand list of files in argument for pre-build event
===

I'm trying to run a pre-build event which passes all the JavaScript files in a directory to MS's Ajax Minifier. Unfortunately, this tool excepts file names as individual arguments (it cannot parse "\*.js"). I have quite a few JavaScript files and I really don't want to list them individually in the pre-build event window. 

This is my current pre-build command:

    "$(SolutionDir)Tools\AjaxMin.exe" "$(ProjectDir)*.js" -out  "$(ProjectDir)Generated\Generated.js" -clobber

Does anyone know the proper syntax (or if there even is one) to make this do what you'd expect it to do?

Thanks for any assistance.
