Now that I think about it, I'd like to put the multi-gnulib support
directly into my bootstrap script so that it can be called by setting
some configuration variables in bootstrap.conf rather than proliferating
a hook function among all the projects that need this particular
functionality.

Otherwise the pattern for extending bootstrap.conf is something like this:

my_gnulibize_again ()
{
    $func_debug

    $require_gnulib_tool

    (
      docbase=...
      gnulib_mk=...
      gnulib_name=...
      local_gl_dir=...
      source_base=...
      tests_base=...

      gnulib_tool_options='...'
      gnulib_modules='...'
      gnulib_non_module_files='...'

      gnulib_cmd=`echo $gnulib_tool $gnulib_tool_options $gnulib_modules`

      func_show_eval "$gnulib_cmd" 'exit $?'
    ) || exit 1
}
func_add_hook func_gnulib_tool my_gnulibize_again


What project did you have in mind?  I'll compare the needs of yours
and GNU M4, and bake in that functionality to the next version of
my bootstrap script.

Cheers,
