""" Library to implement a well-behaved Unix daemon process.
This library implements the well-behaved daemon specification of
:pep:`3143`, "Standard daemon process library".
A well-behaved Unix daemon process is tricky to get right, but the
required steps are much the same for every daemon program. A
`DaemonContext` instance holds the behaviour and configured
process environment for the program; use the instance as a context
manager to enter a daemon state.
Simple example of usage::
import daemon
from spam import do_main_program
with daemon.DaemonContext():
do_main_program()
Customisation of the steps to become a daemon is available by
setting options on the `DaemonContext` instance; see the
documentation for that class for each option.
