 * DESCRIPTION: INTERFACE FOR THE "utils" LIBRARY. THIS HEADER 
 *              CONTAINS DEFINITIONS OF FUNCTIONS THAT OFTEN HAPPEN
 *              TO USE IN DIFFERENT PROGRAMS.
 *              ALSO THE HEADER DEFINES MACROS TO IMPROVE
 *              THE PORTABILITY OF THE VARIOUS PROGRAMS AND DEFINES OF THE MACROS
 *              FOR COLORS.
 * VERSION:     1.5
