+ *
+ * The error reporting and logging infrastructure used across ck.
+ * This file defines the basic macros other functions should call to
+ * report problems or help the user.
+ *
+ * All macros use printf like syntax to format the resutling strings.
+ * There is no need for newline (`\n`) it is automatically appended to
+ * each string.
+ *
+ * ERRLOG(component-name)
+ *   Should be called once in every .c file defining the component name
+ *   to be used with error reporting and logging.
+ *
+ * LOG("format-string", ...)
+ *   Add format-string to the log. The component name is prepended.
+ *   The log can be saved to a logfile and/or printed at the end of
+ *   the ck session provided the --verbose flag is active.
+ *
+ * ERR("format-string", ...)
+ *   Reports the format-string at the moment of calling, prepended with
+ *   Error and the component-name. Also adds the error to the log.
+ *
+ * HELP("format-string", ...)
+ *   Print the format-string at the moment of calling, without adding
+ *   any component name nor pushing the string to the log.
