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