*  Description:

*

*     Logging tools. Uniforms style to write debug data to

*     file with RFileLogger.

*

*     Usage:

*

*       following directory must be manually done before logging

*       (no directory, not logs).

*           Epoc32\Winscw\c\logs\bsimport\

*

*

*     2.Printing:

*

*       // normal string                                  output:

*       IMPORT_DP( D_IMPORT_LIT( "Some text." ) );                >> CHAT: Some text.

*       IMPORT_DP( D_PLAIN_LIT( "Some text." ) );               >> Some text.

*       IMPORT_DP_TXT( "Some text." );                          >> CHAT: Some text.

*

*       // string with variables

*       TInt index( 99 );

*       _LIT( KExample, "Example" );

*       IMPORT_DP( D_IMPORT_LIT( "Some text: %d" ), 100 );        >> CHAT: Some text: 100

*       IMPORT_DP( D_IMPORT_LIT( "Some text: %d" ), index );      >> CHAT: Some text: 99

*       IMPORT_DP( D_IMPORT_LIT( "Some text: %S" ), &KExample );  >> CHAT: Some text: Example

*

*       IMPORT_DP( D_PLAIN_LIT( "Some text: %d" ), 100 );       >> Some text: 100

*       IMPORT_DP( D_PLAIN_LIT( "Some text: %d" ), index );     >> Some text: 99

*       IMPORT_DP( D_PLAIN_LIT( "Some text: %S" ), &KExample ); >> Some text: Example

*

*

*     3.Known issues:

*

*       - If you use macros from .mmp file remember to abld makefile <target> to

*         change flags from project.

*       - In statements like IMPORT_DP( D_IMPORT_LIT("Some text: %S"), &KExample );

*         parameters causes still some code to generated in release builds.

*         Propably it is best to #ifdef all debugprint blocks

*         with CHAT_ENABLE_DEBUG_PRINT statement.
