How to use:

Here is the logger initialization:

Logger l = Logger.getInstance();

Now, where you need, you can call:

l.write( Tag.DEBUG, "xxxx" );

to write a DEBUG string on Standard out.

When you put your code in production, you can set this Logger to exclude DEBUG log:

l.disableTag( Tag.DEBUG );

and change the out stream on File (for example):

l.setPrintStream(new PrintStream(new File("path/to/file.log")));
