  my_fifo = queue.create_tube('my_fifo', 'fifo')
end
```

> chmod +x app.lua

# Next stage, connect to server console (like lua console) and manage fifo tube

Methods for manage tasks:
  :put('some_data')
  :take([timeout]) - take a task from FIFO tube
  :bury(task_id) - bury task
  :kick(count_of_tasks) - if somithing will wrong, you can liven up count of tasks (like after byru task)
  :delete(task_id) - remove task from queue
  :ack(task_id) - complite the task (also will removed from queue)

# Create a task
my_fifo:put('some_data')

my_task = my_fifo:take() -- take a task from FIFO tube

#  task with data:
#  1 - task id,
#  2 - status of task:
#    'r' - ready for run,
#    't' - taken and working with that task,
#    '-' - complited and removed from queue,
#    '!' - bury task,
#    '~' - delaeyd task
#  3 - data field

# do something with data from my_task[3] and then complite task with next method
my_fifo:ack(my_task[1])
- [0, '-', 'some_data']
