 // WMI (Windows Management and Instrumentation) is a big, complex, COM-based
 // API that can be used to perform all sorts of things. Sometimes is the best
 // way to accomplish something under windows but its lack of an approachable
 // C++ interface prevents its use. This collection of fucntions is a step in
 // that direction.
 // There are two classes; WMIUtil and WMIProcessUtil. The first
 // one contain generic helpers and the second one contains the only
 // functionality that is needed right now which is to use WMI to launch a
 // process.
 // To use any function on this header you must call CoInitialize or
 // CoInitializeEx beforehand.
