+"""A basic unix daemon using the python-daemon library:
+http://pypi.python.org/pypi/python-daemon
+
+Example usages:
+
+ $ python unix_daemon.py start
+ $ python unix_daemon.py stop
+ $ python unix_daemon.py status
+ $ python unix_daemon.py  # foreground (no daemon)
+ $ python unix_daemon.py --logfile /var/log/ftpd.log start
+ $ python unix_daemon.py --pidfile /var/run/ftpd.pid start
+
+This is just a proof of concept which demonstrates how to daemonize
+the FTP server.
+You might want to use this as an example and provide the necessary
+customizations.
+
+Parts you might want to customize are:
+ - UMASK, WORKDIR, HOST, PORT constants
+ - get_server() function (to define users and customize FTP handler)
