  35 Bootstrap this package from the CVS sources.

  37 Options:
  38  --gnulib-srcdir=DIRNAME  Specify the local directory where gnulib
  39                           sources reside.  Use this if you already
  40                           have gnulib sources on your machine, and
  41                           do not want to waste your bandwidth dowloading
  42                           them again.
  43  --copy                   Copy files instead of creating symbolic links.
  44  --force                  Bootstrap even if the sources didn't come from CVS.
  45  --skip-po                Do not download po files.
  46  --cvs-user=USERNAME      Set the CVS username to be used when accessing
  47                           the gnulib repository.
  48
  49 If the file .bootstrap.conf exists in the current working directory, its
  50 contents are read as shell variables to configure the bootstrap.
  51
  52 Running without arguments will suffice in most cases.
