  Starting off with...

  I'll gladly take any of them.  One more thing; in this mode, you
*MUST* use a leading minus for "-cvzf".  The lazy "cvzf" will *NOT*
work, and throws a misleading error message.  See also my post to
Michael about the contents of the CACHEDIR.TAG file.

pop-up windows self-replicating, trying to uninstall RealPlayer.  All
those moments, will be lost in time like tears in rain... time to die.
