   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

   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:  --cvs-user=USERNAME      Set the username to use when checking out
   53:                           sources from the gnulib repository.
   54: 
   55: If the file .bootstrap.conf exists in the current working directory, its
   56: contents are read as shell variables to configure the bootstrap.
   57: 
   58: Running without arguments will suffice in most cases.
