-CHANGELOG
+COMMIT MESSAGES
 
-Add a ChangeLog entry whenever changing code, except for minor fixes
-to a commit (with a ChangeLog entry) within the last few days.
+The commit message should provide:
 
-Most directories have a ChangeLog file; changes to code in that
-directory should go in the per-directory ChangeLog.  Global or
-structural changes should also be mentioned in the top-level
-ChangeLog.
+* A suitable one-line summary as the very first line of the message, in the
+  form:
 
-Certain directories do not contain project code, but contain project
-meta-data, eg packaging information, changes to files in these
-directory may not require the global ChangeLog to be updated (at the
-discretion of the maintainer who usually maintains that meta-data).
-Also, CVS meta-data such as cvsignore files do not require ChangeLog
-updates, just a sane commit message.
+  [topic] high-level, one line summary
 
-The ChangeLog should provide:
+  Where topic may be name of a subdirectory, and/or daemon. 
 
-* The date, in YYYY-MM-DD format
-* The author's name and email.
-* a short description of each change made
+* An optional introduction, discussing the general intent of the change.
+* a short description of each change made, preferably:
   * file by file
-    * function by function (use of "ditto" is allowed)
+    * function by function (use of "ditto", or globs 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

+* Send a clean diff against the 'master' branch of the quagga.git

-* Include ChangeLog and NEWS entries as appropriate before the patch

-PATCH APPLICATION TO CVS
+PATCH APPLICATION
 
 * Only apply patches that meet the submission guidelines.
 
-* If a patch is large (perhaps more than 100 new/changed lines), tag
-  the repository before and after the change with e.g. before-foo-fix
-  and after-foo-fix.
-
 * If the patch might break something, issue a call for testing on the
   mailinglist.
 
-* Give an appropriate commit message, prefixed with a category name
-  (either the name of the daemon, the library component or the general
-  topic) and a one-line short summary of the change as the first line,
-  suitable for use as a Subject in an email. The ChangeLog entry should
-  suffice as the body of the commit message, if it does not, then the
-  ChangeLog entry itself needs to be corrected. The commit message text
-  should be identical to that added to the ChangeLog message. (One
-  suggestion: when commiting, use your editor to read in the ChangeLog
-  and delete all previous ChangeLogs.) An example:
-  
-  ----------------------------------------------------------------
-  [frob] Defangulator needs to specify frob
-  
-  2012-05-12 Joe Bar <joe@example.com>
-  
-  	* frobinate.c: (frob_lookup) fix NULL dereference
-  	  (defangulate) check whether frob is in state FROB_VALID
-  	  before defangulating.
-  ----------------------------------------------------------------
+* Give an appropriate commit message (see above), and use the --author
+  argument to git-commit, if required, to ensure proper attribution (you
+  should still be listed as committer)
+
+* Immediately after commiting, double-check (with git-log and/or gitk). If
+  there's a small mistake you can easily fix it with 'git commit --amend ..'
 
 * By committing a patch, you are responsible for fixing problems
   resulting from it (or backing it out).
