Yep - the standalone bang.exe is nice if you want to stick it in a folder with a vbscript though, since the vbscript has no simple way of knowing the correct path to litestep.exe. It knows its own folder, though, so you can just drop a copy of bang.exe in there for it to use. You *could* dig in the registry for the path to the LS executable, assuming LS has been installed in the usual fashion.

As far as mzscript args go, yes, you can pass it stuff. From the 0.9.13 *docs* (hint, hint =P):
