This will be quick, mostly because elmer is quick and quiet on its own.
For what I’ve seen of elmer, it seems slightly incomplete, or perhaps it’s just a personal project and not really intended for the outside world. No man page to speak of, and only a short list of flags without much prompting.
By default it sends everything to codepad.org, like I mentioned, but uses environment variables to adjust that or to list alternatives.
On the other hand, it strikes me as very light, very focused, and perhaps most importantly … functional. I can’t find fault with that. 😐
