  40 Bootstrap this package from the checked-out sources.

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