  29 Usage: $ME
  30
  31 Run this script from top_srcdir (no arguments) after each non-alpha
  32 release, to update the web documentation at
  33 http://www.gnu.org/software/\$pkg/manual/
  34
  35 This script assumes you're using git for revision control, and
  36 requires a .prev-version file as well as a Makefile, from which it
  37 extracts the version number and package name, respectively.  Also, it
  38 assumes all documentation is in the doc/ sub-directory.
  39
  40 Options:
  41   -C, --builddir=DIR  location of (configured) Makefile (default: .)
  42   -n, --dry-run       don't actually commit anything
  43   -m, --mirror        remove out of date files from document server
  44   --help              print this help, then exit
  45   --version           print version number, then exit
  46
  47 Report bugs and patches to <bug-gnulib@gnu.org>.
