Software developed to build our "Brains Copy Paste" paper, analyzing mutation in quotes when they propagate through the blog- and news-spaces (this should tell us stuff on how the brain copy-pastes and alters quotes when doing so).
The latex source (along with compiled pdf) for the paper is at wehlutyk/brainscopypaste-paper.
See the documentation if you want to install, run, or understand any of this. A substantial effort has gone into making this code readable and well-documented, so please feel free to use or review it if you need to or want to!
If you find a bug, a mistake, or anything you think needs changing, please file an issue.
