  35 Bootstrap this package from the checked-out sources.

  37 Options:
  38  --paxutils-srcdir=DIRNAME  Specify the local directory where paxutils
  39                           sources reside. Use this if you already
  40                           have paxutils sources on your machine, and
  41                           do not want to waste your bandwidth dowloading
  42                           them again.
  43  --gnulib-srcdir=DIRNAME  Specify the local directory where gnulib
  44                           sources reside.  Use this if you already
  45                           have gnulib sources on your machine, and
  46                           do not want to waste your bandwidth dowloading
  47                           them again.
  48  --copy                   Copy files instead of creating symbolic links.
  49  --force                  Attempt to bootstrap even if the sources seem
  50                           not to have been checked out.
  51  --skip-po                Do not download po files.
  52  --update-po[=LANG]       Update po file(s) and exit.
  53  --cvs-user=USERNAME      Set the CVS username to be used when accessing
  54                           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 Local defaults can be provided by placing the file \`.bootstrap' in the
  60 current working directory.  The file is read after bootstrap.conf, comments
  61 and empty lines are removed, shell variables expanded and the result is
  62 prepended to the command line options.
  63
  64 Running without arguments will suffice in most cases.
