Which doesn't directly reference the "most complete" FreeView howto:

Someone could move it to pvr.geek.nz if they wish, but I think it's best to
have one empirical source for data like this (I've had wiki pages lifted
from WLUG to things like the OpenSwan wiki before, and changes to one don't
update the other), and it just so happens when I figure things out I tend to
put them on the WLUG wiki. :)
