 It is possible to schedule tasks with a delay, which can then be canceled again in case a canceling event occurs. A useful example for this is to run tasks only if a file has not changed within a certain amount of time.

 pyinotifyd has different schedulers to schedule tasks with an optional delay. The advantages of using a scheduler are consistent logging and the possibility to cancel delayed tasks. Furthermore, schedulers have the ability to differentiate between files and directories.
 
 ### TaskScheduler
-Schedule a custom python method *job* with an optional *delay* in seconds. Skip scheduling of tasks for files and/or directories according to *files* and *dirs* arguments. If there already is a scheduled task, re-schedule it with *delay*. Use *logname* in log messages.

If there already is a scheduled task, re-schedule it with *delay*. Use *logname* in log messages. All additional modules, functions and variables that are defined in the config file and are needed within the *job*, need to be passed as dictionary to the TaskManager through *global_vars*. If you want to limit the scheduler to run only one job at a time, set *singlejob* to True.  
 All arguments except for *job* are optional.
