There's an example of how to do this (which I think I took from Python
Standard Library) in the Daemon class in gmalib. It use's gmalib's
Logger class to send all output to either a normal file, or syslog.

You can download gmalib here:

  http://sourceforge.net/project/showfiles.php?group_id=34228

or save yourself the trouble by browsing the CVS archive first:

 
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/landialler/gmalib/gmalib.py?rev=1.10&content-type=text/vnd.viewcvs-markup

It's GPL'd, so feel free to re-use, etc.

Example usage:

  import gmalib

  class MyApp(gmalib.Daemon):
      def __init__(self):
          gmalib.Daemon.__init__(self, logfile="log.txt", use_syslog=0)
          self.daemonise()
