## Details

Information gathered from the appendix of Thompson and Dreyer (2012). Ongoing rivalries are right-bound at 2010, the date of publication for Thompson and Dreyer's handbook. Users are free to change this if they like. Data are effectively identical to strategic_rivalries in stevemisc, but include some behind-the-scenes processing (described in a blog post on http://svmiller.com) that is available to see on the project's Github repository. The data object is also renamed to avoid a conflict.
