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

// 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 :
//		Tokenizes the commandline string and serves them up one by one for
//		COXCommandOptions::ParseCommandLine().  Constructor has two forms, one which
//		takes a CStdioFile pointer to support response files to get arround cmd line
//		limitations, the other takes a Character pointer.

// Remark:

// Prerequisites (necessary conditions):
//		***
