  41 Bootstrap this package from the checked-out sources.

  43 Options:
  44  --gnulib-srcdir=DIRNAME  Specify the local directory where gnulib
  45                           sources reside.  Use this if you already
  46                           have gnulib sources on your machine, and
  47                           do not want to waste your bandwidth downloading
  48                           them again.
  49  --copy                   Copy files instead of creating symbolic links.
  50  --force                  Attempt to bootstrap even if the sources seem
  51                           not to have been checked out.
  52  --skip-po                Do not download po files.
  53  --cvs-user=USERNAME      Set the username to use when checking out
  54                           sources from the gnulib repository.
  55
  56 If the file bootstrap.conf exists in the current working directory, its
  57 contents are read as shell variables to configure the bootstrap.
  58
  59 Running without arguments will suffice in most cases.
