I see. I  will be wary of my  world file from now on. I'm  glad that you
mentioned this now  since I don't have that much  packages installed yet
and I haven't played around with the system enough that there's a chance
that it might break. Knowing this is  really handy since it might not be
apparent when things that shouldn't be added in the world file are being
added to the world file.

I am actually very interested with  sets. I haven't read enough about it
though. But  I think  I will try  it out,  it might be  a neater  way of
dealing with packages.
