Is there a way to make logger not write the header line (first line) of  
a log  
file? I’d rather it not write anything but log entries.

log\_entry  
log\_entry  
log\_entry  
…

Thanks,  
Brad

```
$ cat b.rb
require 'logger'

class MyLogger < Logger
  def add_log_header(*a, &b) 42 end
end

logger = MyLogger.new STDERR

logger.info{ "implementation inheritance is useful at times" }

$ ruby b.rb
