I need to modify the log system we currently have. At the moment it writes
out to 4 separate files: warnings.log, trace.log, errors.log and notice.log.
What I need to do is to have only two log files: trace.log and errors.log
The detail of the info in the trace.log file needs to be set on three
levels. I need to set up variable that can be set to "compact", "verbose"
and "debug" depending on the current settings. If anyone could give me a
hint on how I would do it. Thanx much!
In case is someone is interested to take a look at the code, here it is:
