+This script calculates the per-function absolute result count (EAFC) for the
+"inject-on-write" fault model, which assumes that writes to memory can get
+corrupted, and completely disregards storage duration (e.g. time between write
+and subsequent read).  The metric is calculated from the results of a normal
+"inject-on-read" campaign, only using the FI results from memory accesses that
+directly follow a "write" access.

+# This implementation makes sure the write -- not the subsequent memory access
+# that determines the result type -- happens in the context of the
+# corresponding function.
+#
+# Currently does not take into account right-margin writes, i.e. those
+# that are not followed by *any* memory access.  This is mostly OK as
+# import-trace creates synthetic 'write' events at the right margin for
+# all but those memory accesses that are exactly on the right margin
+# already.
