+The ChangeLog should provide:

+* a short description of each change made
+ * file by file
+ * function by function (use of "ditto" is allowed)

+(detailed discussion of non-obvious reasoning behind and/or
+implications of a change should be made in comments in the code
+concerned). The changelog optionally may have a (general) description,
+to provide a short description of the general intent of the patch. The
+reason for such itemised ChangeLogs is to encourage the author to
+self-review every line of the patch, as well as provide reviewers an
+index of which changes are intended, along with a short description for
+each. E.g.:

+ * (general) Add a new DOWN state to the frob state machine

+ * frob.h: (struct frob) Add DOWN state flag.
+ * frob.c: (frob_change) set/clear DOWN appropriately on state
+ change.
+ * bar.c: (barinate) Check frob for DOWN state.
