Hi

Finally It worked......Submitting the patch for review.

Now xfce4-embed-plugin is building fine after i modified the input to
old version of libxfce4ui.

I referred the older commit message from help2man from the log. I am
still not sure about it.

Its the same code i have sent you. I used the origin block. And (name  
x) was the only difference.

I used the same. I added name block. It worked !!!

It worked the same.

1) If name block is removed in latest.   Its building the older version.
Why??

2)  /latest is also removed from variable. Would i make a difference?

Thanks for such a long explanation. It took a bit of time for me.
