how to control program output in the way warning() does

I like the design of warning() and tried to use it to control my program output. However it shows "warning" all the time, which is not what I want.

Some other designs use verbose level parameter to control what information should be printed out. However, that approach seems tedious.

What do you use to control your program output messages?
