Sure, but nowadays the preferred interface is the GUI.
What I really wanted was to have custom postlink processing performed automatically when the user hits "Make", but I already found that can't be done.
The workaround I have is to pass the variables into the batch file, strip the quotes, then change directory inside the batch file. This means that there must be a batch file on the path (or fixed location), which requires extra setup, but it works.
I might rewrite the batch file as a .exe, but the same method could be used.
