Everyone has to learn lavishscript from scratch and figure it out. Any of the bots you've seen for any of the InnerSpace supported games were created by authors taking a LOT of time to learn how it works, etc. There just are simply no quick routes.
There are bots out there that are being written and supported by people RIGHT NOW (they're here on the forums and announced on the IRC channel topic); however, EVEBot is open-source and does not currently have a supporter/author. So, yea, you either have to learn it and support it yourself ...or, use another product. This is the way it is with all software .... (At least in this instance it's open source so you could fix it up if you wanted.)
