I see that Helm installation from nongnu elpa doesn't include
emacs-helm.sh script, would it be possible to modify this?

        diff --git a/elpa-packages b/elpa-packages

Also I asked here about a new dependency for Helm called wfnames and had
no answer (2 times), so I ask again differently now:
When a package is available in Melpa do we have to add it in nongnu as
well to satisfy dependencies for a package already in nongnu?

Thanks.
