+`git format-patch` can include an initial "cover letter". You can insert
+commentary on individual patches after the three dash line which
+`format-patch` places after the commit message but before the patch

+`git format-patch --notes` will include the commit's notes in a similar
+manner.

use the linkgit:git-send-email[1] script to automate the process.
