//comment added by WPQS
//program takes an optional single parameter, the version of CLR to find. The program returns 0 (success)
//if this version of CLR is found, otherwise it returns -1 (fail). If no parameter is given the program
//returns 0 (success).
//
// examples:
//	c:\>DetectDotNet 1.2.4455  //returns 0 if version 1.2.4455 is found
//	c:\>DetectDotNet 2.0*	   //returns 0 if any version 2.0 of CLR is found
//	c:\>DetectDotNet 1.*	   //returns 0 if any version 1. of CLR is found
//	c:\>DetectDotNet *		   //returns 0 if any version of CLR is found
//	c:\>DetectDotNet 		   //returns 0 whether a version of CLR is found or not
