I've appended the one I use. I import from a CVS checkout, so I
need need to ignore that stuff, but that, and the paths, are about
the only tweaks you should have to make.

Note that this requires a fair amount of disk space; I use compare
a -current against a clean checkout of the head of my private tree
in order to determine which files in my private tree I need to
delete after an import.
