Ummm... No. I never have used quilt.

Ah, there is a series file. I guess it would not be too hard to make
an appropriate "sh" command:

cat /tmp/patch-2.6.29-rc3-lttng-0.92/series | grep -v '^#' | sed -e 's/^/patch
-p1 < \/tmp\/patch-2.6.29-rc3-lttng-0.92\//' | sh

But this complains about directories. OK, "sudo apt-get install quilt"
followed by "man quilt". Than "quilt import" seems to do some of the
work, but doesn't seem to apply all the patches. Thank goodness for
"git reset --hard"!!!

Help?

Thanx, Paul
