  41 Options:
  42  --gnulib-srcdir=DIRNAME  Specify the local directory where gnulib
  43                           sources reside.  Use this if you already
  44                           have gnulib sources on your machine, and
  45                           do not want to waste your bandwidth downloading
  46                           them again.
  47  --copy                   Copy files instead of creating symbolic links.
  48  --force                  Attempt to bootstrap even if the sources seem
  49                           not to have been checked out.
  50  --skip-po                Do not download po files.
  51
  52 If the file $0.conf exists in the same directory as this script, its
  53 contents are read as shell variables to configure the bootstrap.
  54
  55 For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
  56 are honored.
  57
  58 Running without arguments will suffice in most cases.
