Don't expect anything fancy (at least yet... My free time is close to 0, I'm doing this while waiting for something else to finish...) I'm still deciding what I want it to do and how. For now, the magic function does its job... (I can open included files in TeX documents and jump from TeX output undefined lines to the respective file and line.) And my code is full of messages and lacking a clear structure of region selection. I need many helper functions down the road. But stay tuned, everything can improve :)
No, I used to hold some code in my googlecode repo, but gave up a long time ago. Until I get more proficient with git, I'll probably just post it in my blog (and then the marmalade-repo, just like I did with gnusnotes.el) when it is decent enough for general usage
