^^^^ Thanks, now I know. I'll make a handler object for this and I'll make it in
way to use both Pi3Perl and standard Perl scripts.

I'll make a list of what I've found out ASAP. Then I'll call you back.
Look at the auth.pl once more. Compare the call of it from the config and the
script-variables. You can see some variables are read from database but other
global values like $AuthFile are set from corresponding config entries!
Sorry, must hurry now to be not to late at work.
