  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 bootstrap.conf exists in the current working directory, its
  53 contents are read as shell variables to configure the bootstrap.
  54
  55 Running without arguments will suffice in most cases.
