 Requirements:
 - you use git for version-control
-- a NEWS file, with line 3 identical to this:
-* Noteworthy changes in release ?.? (????-??-??) [?]
 - a version-controlled .prev-version file
+- a NEWS file, with line 3 identical to this:
+$noteworthy_stub
 
 Options:
-  --help     print this help, then exit
-  --version  print version number, then exit
+  --branch=BRANCH     set release branch (default: $branch)
+  -C, --builddir=DIR  location of (configured) Makefile (default: $builddir)
+  --help              print this help, then exit
+  --version           print version number, then exit
