‘daemon’ is a library that assists a Python program to turn itself into a well-behaved Unix daemon process, as specified in PEP 3143.

This library provides a ‘DaemonContext’ class that manages the following important tasks for becoming a daemon process:

* Detach the process into its own process group. * Set process environment appropriate for running inside a chroot. * Renounce suid and sgid privileges. * Close all open file descriptors. * Change the working directory, uid, gid, and umask. * Set appropriate signal handlers. * Open new file descriptors for stdin, stdout, and stderr. * Manage a specified PID lock file. * Register cleanup functions for at-exit processing.

This package installs the library for Python 3.
