+# Therefore these can add content to be included into the release-
+# commit. These commands have access to the `TAG_VERSION` variable
+# which contains the tag to be applied after the commit. If the
+# command specified here is prefixed with a `-` sign, the exit status
+# will not fail the release process. If it is not prefixed with a `-`
+# a non-zero exit status will terminate the release process. The
+# commands will be run from the repostory root, so sub-dirs MUST be
+# specified. All commands are run as `bash -ec "..."` so you can use
+# bash inside the commands.
