    GNULIB_REFDIR            Specifies the local directory where a gnulib
                             repository (with a .git subdirectory) resides.
                             Use this if you already have gnulib sources
                             and history on your machine, and do not want
                             to waste your bandwidth downloading them again.
    GNULIB_URL               URL of the gnulib repository.  The default is
                             $default_gnulib_url,
                             which is Gnulib's upstream repository.

                             not to have been checked out.
    --no-git                 Do not use git to update gnulib.  Requires that
                             \$GNULIB_SRCDIR points to a gnulib repository
                             with the correct revision.

  If the file bootstrap.conf exists in the same directory as this script, its
  contents are read as shell variables to configure the bootstrap.
  
  For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
  are honored.
  
  Gnulib sources can be fetched in various ways:
  
   * If the environment variable GNULIB_SRCDIR is set, then sources are
     fetched from that local directory.  If it is a git repository and the
     configuration variable GNULIB_REVISION is set in bootstrap.conf, then
     that revision is checked out.
  
   * Otherwise, if this package is in a git repository with a 'gnulib'
     submodule configured, then that submodule is initialized and updated
     and sources are fetched from there.  If the environment variable
     GNULIB_REFDIR is set and is a git repository, then it is used as a
     reference.
  
   * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
     are cloned into that directory using git from \$GNULIB_URL, defaulting
     to $default_gnulib_url; if GNULIB_REFDIR is set and is a git repository
     its contents may be used to accelerate the process.
     If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
     then that revision is checked out.
  
   * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
     used.  If it is a git repository and the configuration variable
     GNULIB_REVISION is set in bootstrap.conf, then that revision is
     checked out.
  
  If you maintain a package and want to pin a particular revision of the
  Gnulib sources that has been tested with your package, then there are
  two possible approaches: either configure a 'gnulib' submodule with the
  appropriate revision, or set GNULIB_REVISION (and if necessary
  GNULIB_URL) in bootstrap.conf.
  
  Running without arguments will suffice in most cases.
