Hi!

I've been playing a little bit with the Python interface and got the
attached script to work. Basically you need to create a class based on
EOG's base plugin class. You can then add the functions "activate" and
"deactivate" which will be called when the user does the corresponding
action in the preferences dialog (activate is also called when the
plugin is loaded on startup).

Looking at EOG's code it can also call a function named
"create_configure_dialog" which can be used to implement configuration
dialogs (yeah, who would have thought so?) and a function called
"update_ui" what I don't know yet what it is good for.

In Bugzilla is also a pythonconsole plugin [1] which might be useful
during development, but this one can (as other python plugins using the
window pointer) provoke a ref-counting issue[2] that stops EOG from
quitting properly. It also shows how to make plugins spanning over
multiple files.

Well, I guess you already noticed that I'm not really into this
Python-thing, so take this carefully. :-)
