+Usage: $ME
+
+Run this script from top_srcdir (no arguments) after each non-alpha
+release, to update the web documentation at
+http://www.gnu.org/software/\$pkg/manual/
+
+This script assumes you're using git for revision control, and
+requires a .prev-version file as well as a Makefile, from which it
+extracts the version number and package name, respectively.  Also, it
+assumes all documentation is in the doc/ sub-directory.
+
+Options:
+  -C, --builddir=DIR  location of (configured) Makefile (default: .)
+  -n, --dry-run       don't actually commit anything
+  --help              print this help, then exit
+  --version           print version number, then exit
+
+Report bugs and patches to <address@hidden>.
