Comment 4 for bug 30878

I'm the author of the plugin, and unfortunately it won't work anymore with maverick; the evolution plugin framework is completely different in evolution 2.32 (compared to 2.28), and a big part of the plugin will need to be rewritten.

Unfortunately, the official documentation (http://projects.gnome.org/evolution/) is now completely irrelevant since it has not been updated in ages, so the new APIs need to be inferred from the evolution source code, which is not very plugin-developer-friendly ...
