   3 # The build failed for and identifier in the range bwetween LOW and HIGH.
   4 # Find a new patch id to try within that range.
   5 #
   6 # It's meant to be easy to modify the heuristics used to select the
   7 # next patch to try by adding to or rearranging the patches listed in
   8 # MIDLIST.  Known failures are recorded in ${REG_FAILLIST}.
   9 #
  10 # A nifty improvement would be to record known ranges of failure as
  11 # ranges, and then pick revisions just before and just after the range.
