  @item
  In projects which commit all source files, whether generated or not, into
  their VCS, the @code{gnulib-tool} generated files should all be committed.
+ In this case, you also pass the option @samp{--no-vc-files} to
+ @code{gnulib-tool}.
  
  Gnulib also contains files generated by @command{make} (and removed by
  @code{make clean}), using information determined by @command{configure}.
