But for better understanding I made the more throughout look into the documentations. I found the information about "postfuncs"= you talk about [1]. However, the tasks description [2] doesn't say anything about including the task in the process, it just describes the demanded order that the task is put ( addtask something after|before othertask ).

That is so, until I read "3.6. Variable Flags"=C2=A0 [3]. Whe= re is quite clearly stated those variables control functionality and *dependencies*.
The documentation is quite unclear in that case.

If you're using a postfunc you don't need to addtask at all: = using postfuncs means you don't need to have a separate task at all.
