Comment # 1 on bug 1049867 from Stanislav Brabec

I agree. The script author is Guido Berhoerster.

To Guido Berhoerster:

$r is apparently there for installation into a sysroot.

You are the author of the script. Are you aware of any application that needs
exactly $r? Is that feature used at all? Or is it only a debugging feature? If
yes, we can keep r, but set
r=
in the script header.
