A rule holds an *action* (move, copy or delete) and a regular expression *src_re*. The FileManager task will be executed if *src_re* matches the path of an event.
If the action is copy or move, the destination path *dst_re* is mandatory and if *action* is delete and *rec* is set to True, non-empty directories will be deleted recursively.
With *auto_create* set to True, possibly missing subdirectories in *dst_re* are created automatically. Regex subgroups or named-subgroups may be used in *src_re* and *dst_re*. Use *logname* in log messages.
The optional *filemode*, *dirmode*, *user* and *group* arguments are applied to every file and/or directory that is processed by FileManager. That includes automatically created subdirectories.
With *auto_create* set to True, possibly missing subdirectories in *dst_re* are created automatically. Regex subgroups or named-subgroups may be used in *src_re* and *dst_re*.
Set the mode of moved/copied files/directories with *filemode* and *dirmode*. Ownership of moved/copied files/directories is set with *user* and *group*. Mode and ownership is also set to automatically created subdirectories.

TaskScheduler schedules *task* with an optional *delay* in seconds. Use the *files* and *dirs* arguments to schedule tasks only for files and/or directories.

### Watches
Watch watches *path* for event types in *event_map* and execute the corresponding task(s). If *rec* is True, a watch will be added on each subdirectory in *path*. If *auto_add* is True, a watch will be added automatically on newly created subdirectories in *path*.

### PyinotifydConfig
pyinotifyd expects an instance of PyinotifydConfig named **pyinotifyd_config** that holds its config options. The options are a list of *watches*, the *loglevel* (see https://docs.python.org/3/library/logging.html#levels) and the *shutdown_timeout*. pyinotifyd will wait *shutdown_timeout* seconds for pending tasks to complete during shutdown.
