Just pass ---  Just explain that to the average user, that does not even 
comprehend there is a command line that arguments can be passed on, or 
that windows uses shortcuts.  Then repeat 500 times.  That is what I am 
expecting in the next release.

Simply put,  a support disaster with "add-on XXX does not work and I 
can't downgrade, how do I fix that bug?"
