Gimp initial setup

[DAVID BALAZIC]

Gimp initial setupWhen running gimp for the first time, it run a wizard for some settings.
Part of it is creating some files and dirs by running some shell comands,
like mkdir and cp. The stdout of the commands is shown and on the botton it
says :
Did you notice any error messages in the lines above?
If not, installation was successful!
Otherwise, quit and investigate the possible reason...

Is this some insider joke ?
Or do the GIMP developers not know of the existance of return codes ?

Version is gimp-1.2.3-20.2 ( fedora test 3 system ).
( hmm, gimp.org has v 1.2.5 )

There is also a screen for manually measuring the display DPI.
It shows two rulers, on each of them is a black triangle arrow that
can be moved by the mouse. What is the purpose of that arrow ?
