// Description:

// This file contains the class definitions and normal definitions for use by 

// the CTelLogger.

// There are two defines that are used to determine which set of macros are to be 

// used.  First, if DEBUG is defined the LOGTEXTn macros are implemented, but the 

// LOGTEXTRELn macros are not. If DEBUG is NOT defined the LOGTEXTn macros are not 

// implemented but the LOGTEXTRELn macros are.

// All of these macros are abstractions for calls to CETelLogger::Write or 

// CETelLogger::WriteFormat.

//
