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