10 : !> The idea is that decisions about where to log should not be done in
11 : !> the code that generates the log, but should be globally changeable
12 : !> a central place.
13 : !> So some care has been taken to have enough information about the
14 : !> place from where the log comes so that in the future intelligent and
15 : !> flexible decisions can be taken by the logger, without having to change
16 : !> other code.
17 : !> \note

19 : !> in my idea they should have been with variable length,
20 : !> (i.e. they should have returned a trim(adjustl(actual_result)))
21 : !> As a logger should be robust, at the moment I have given up.

23 : !> At the moment logging and output refer to the same object
