[Evolution] Evolution Plugins

[neelu_dhiman persistent co in]

Hi everybody
Whosoever people are working on Plugins, can you please tell me ?
Actually I am also working on plugins, may I seek your help wherever I
want ? 
I am currently referring the plugin development document available at
http://www.gnome.org/projects/evolution/developer-doc/eplugin/evolution-plugin-manual.pdf.
But this document is not much clear, a bit complicated. Moreover the
examples are missing, they are not accessible from there. Can you
please refer some other link or document for the same ? 
I will be very much thankful to you.
-Neelu.
