14 """ Library to implement a well-behaved Unix daemon process.
15
16 This library implements the well-behaved daemon specification of
17 :pep:`3143`, “Standard daemon process library”.
18
19 A well-behaved Unix daemon process is tricky to get right, but the
20 required steps are much the same for every daemon program. A
21 `DaemonContext` instance holds the behaviour and configured
22 process environment for the program; use the instance as a context
23 manager to enter a daemon state.
24
25 Simple example of usage::
26
27 import daemon
28
29 from spam import do_main_program
30
31 with daemon.DaemonContext():
32 do_main_program()
33
34 Customisation of the steps to become a daemon is available by
35 setting options on the `DaemonContext` instance; see the
36 documentation for that class for each option.
