After receiving a 16MB zip file of a native solution from a customer today, I've updated CleanSweep to clean out a lot of the crap created by the native build process (the last version was mostly for managed code).

I've also added very, very basic command-line support.  Right now if you provide no command line, it will clean the directory it is run from.  If you want to clean another folder, you pass the full path to the foilder to clean as the command line.
