Changes: 23rd Jan 2009 (David Mytton <david@boxedice.com>)
- Replaced hard coded '/dev/null in __init__ with os.devnull
- Added OS check to conditionally remove code that doesn't
work on OS X
- Added output to console on completion
- Tidied up formatting
11th Mar 2009 (David Mytton <david@boxedice.com>)
- Fixed problem with daemon exiting on Python 2.4
(before SystemExit was part of the Exception base)
13th Aug 2010 (David Mytton <david@boxedice.com>
- Fixed unhandled exception if PID file is empty
