  35  Options are:
  36  --paxutils-srcdir=DIRNAME    Specify the local directory where paxutils
  37                               sources reside. Use this if you already
  38                               have paxutils sources on your machine, and
  39                               do not want to waste your bandwidth dowloading
  40                               them again.
  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 dowloading
  45                               them again.
  46  --cvs-auth=METHOD            Set the CVS access method used for downloading
  47                               gnulib files. METHOD is one of the keywords
  48                               accepted by cvs -d option (see info cvs
  49                               repository).
  50  --cvs-user=USERNAME          Set the CVS username to be used when accessing
  51                               the gnulib repository.
  52  --no-po                      Do not download po files.
  53  --update-po[=LANG]           Update po file(s) and exit.
