  38 Bootstrap this package from the checked-out sources.

  40 Options:
  41  --gnulib-srcdir=DIRNAME  Specify the local directory where gnulib
  42                           sources reside.  Use this if you already
  43                           have gnulib sources on your machine, and
  44                           do not want to waste your bandwidth downloading
  45                           them again.
  46  --copy                   Copy files instead of creating symbolic links.
  47  --force                  Attempt to bootstrap even if the sources seem
  48                           not to have been checked out.
  49  --skip-po                Do not download po files.
  50  --cvs-user=USERNAME      Set the username to use when checking out
  51                           sources from the gnulib repository.
  52
  53 If the file .bootstrap.conf exists in the current working directory, its
  54 contents are read as shell variables to configure the bootstrap.
  55
  56 Running without arguments will suffice in most cases.
