[Evolution-hackers] Evolution Plugins Guide?

[Onyeibo Oku <twohotis gmail com>]

Greetings

How does one begin to script plugins for Evolution.
I'm considering an exploration into mail-merging.  Similar to this one
for Thunderbird
( https://addons.mozilla.org/en-US/thunderbird/addon/mail-merge/ )

How can one begin to navigate towards realising this?  Any guides,
libraries, SDK etc. that I need to look at?  Is it something an
intermediate scripting enthusiast can handle? (I do python mainly)

Regards
