Cygnus is a framework for writing a MediaWiki-Bot. It has no built in scripts that you can already use, you may find these at other repos.
Cygnus has already a lot of features, however it looks like we won't stop adding new features. Currently, we have a lot of API-functions implemented, like reading, writing, read only a section, edit only a section, move a page, get all pages of a category, get all embeddings of a template and in the new version you will find some sysop functions as well, like blocking a user.
How to get help
Each function at BotCore and DBCore has a small documentation text, where you can find which params you have to use, or which return values you can except. We are working on writing a tutorial as well.
If you want to ask us, you may find us at ##Cygnus on freenode.
