@aklt: No, not yet. But the selection making is an excellent suggestion. I had completely missed that one. Won’t be there for a while, but I think I’ll eventually try and include that too. The big hurdle will be working it in the syntax. (I’m already thinking of scripts that can select all empty lines from current point, select a group, etc…)
@vV: That’s what I for one am using. 
I’ll eventually put out a dedicated thread with a more robust release. The one I posted for elmex is flawed here and there, and won’t work with all the planned syntax. The manual should give you a general idea on the available commands and the syntax in general. But I think I’m going to include a quickstart guide as well. Nothing is as frustrating as trying to get something done and facing a thorough manual of everything…
Status update, though: got the xpcall() -thing working, and as a result I can clean up the logging and error handling into a general, tidy format. When that is done, I’ll try and stop adding complete new features (hard to achieve this goal… aaaa-a…) and try to make the thing work reliably as an feature-incomplete whole. Then it’s first official release time. 
plus a note @vV: Special thanks for making me pick this seriously up again! 
AND an edit: It struck me that the selection thing is a very light addition, I’ll just add a " -select" flag for it! Thanks, aklt! This is what I love and hate in the development of this tool. The new, tasty ideas just keep on flowing in.
