bitkeeper revision 1.1159.258.115 (428354804NJckGgn06IblzmoXJ6F4A)

Many files:
  Add additional intermediate tree (e.g. ref-linux-2.6.11) which is a pristine
  tree with the patches from patches/$(OS)-$(OS_VER) applied.  The pristine tree
  is really pristine now.  Also add dependency of ref-$(OS)-$(OS_VER) tree on
  patches in patches/$(OS)-$(OS_VER).
ignore:
  Add ref-*
