// //////////////////////////////////////////////////////////////////////////

// Properties:
//	NO	Abstract class (does not have any objects)
//	YES	Derived from CObject

//	NO	Is a Cwnd.                     
//	NO	Two stage creation (constructor & Create())
//	NO	Has a message map
//	NO 	Needs a resource (template)

//	NO	Persistent objects (saveable on disk)      
//	Yes	Uses exceptions (same as CFile)

// //////////////////////////////////////////////////////////////////////////

// Desciption :
//		Contains information about a command option, its full name, abbreviations, 
//		description, etc.
//		For detailed explanation, see constructor with parameters.

// Remark:
//		   The option descriptor class, each instance of 
//		   this class represents a valid option to the 
//		   program and some properties about that option.
//		   Can be used by CmdOptions to produce a 
//		   usage message as well as to parse valid options.
// Example: 
//  void CMyApp::CreateValidOptions()
//		{
//		COXCommandOptionDesc codHelp  (_T("HELP"),      NULL,        _T("Prints a help message"));
//		COXCommandOptionDesc codRun   (_T("RUN"),       NULL,        _T("Automatically execute a testcase"));
//		COXCommandOptionDesc codEmf   (_T("EMF"),       COD_LASTARG, _T("MetaFile which specified GDI calls to make"));
//		COXCommandOptionDesc codVerify(_T("VERIFY"),    COD_ARGOK,   _T("Verification option"));
//		COXCommandOptionDesc codDiff  (_T("DIFFERENCE"),COD_FIRSTARG,_T("File to write screen differences to"));
//		COXCommandOptionDesc codCmpScr(_T("CMPSCR"),    COD_FIRSTARG,_T("File to compare screen to"));
//		COXCommandOptionDesc codOutScr(_T("OUTSCR"),    COD_FIRSTARG,_T("File to write actual screen to"));
//		COXCommandOptionDesc codMask  (_T("MASK"),      COD_FIRSTARG,_T("File to mask screen differences with"));
//		COXCommandOptionDesc codCrc   (_T("CRC"),       COD_FIRSTARG,_T("File to read/write CRC code from/to"));
//		COXCommandOptionDesc codGen   (_T("GENERATE"),  NULL,        _T("Interactive session for generating EMF file"));
//		COXCommandOptionDesc codRes   (_T("RES"),       COD_ARRAY,   _T("Resources available"));
//		COXCommandOptionDesc codXList (_T("X"),         COD_ASSOCARRAY,_T("Variable/Value pairs"));
//		}

	//					COD_REP_ARRAY	Build array if option is repeated
	//					COD_ASSOCIATIVE	Takes two arguments i.e. /D variable=value or /D variable value
	//					COD_FIRSTARG	Takes an argument, is repeatable, and repeats are ignored
	//					COD_LASTARG		Takes an argument, is repeatable, and repeats are ignored
	//					COD_ARRAY		Takes an argument, is repeatable, builds an array
	//									(i.e. The INCLUDE option would use this)
	//					COD_ASSOCARRAY	Takes two arguments, is repeatable, builds associative array	
	//									
	//			 psczDescription : the description of the option, for usage messages
	//			 psczAbbr : the abbreviation of the option.
	//						A DEFINITE abbreviation of the argument, this abbreviation will
	//						be used unless it conflicts with another option's DEFINITE abbreviation.
	//						This can be used to have an abbreviation of I for the INCLUDE option, even
	//						if there is another option which begins with I.
	//						For all options, any UNIQUE shortening of the option name is acceptable.
	//						For example, with an option name of INCLUDE, possible abbreviations would
	//						be I, IN, INC, INCL, INCLU, INCLUD.  Which of these possibilities are
	//						valid, depends on which ones are are unique for a given option set.
	//						The DEFINITE abbreviation need not be a true abbreviation of the option name.
	//						For example, an option name EXPORT, could have a DEFINITE abbreviation
	//						of X even though that is not strictly an abbreviation of the name.
