Detailed Description

The file contains the logging macros

Each of the macros behave like printf()

Sample usage:

LOG_DEBUG("Maybe i can touch this button...");
LOG_INFO("Pressure is dropping...");
LOG_ERROR("Houston we have a problem!");
int going_down = 1;
LOG_IF_ERROR(going_down, "i'm going down... if only i had used macro-logger...");
