For those who are unfamiliar, UVa Online Judge is a very good but somewhat dated platform for online programming contests and practicing in competitive programming.
I've been practicing in solving competitive programming problems (that is mainly algorithmic problems) using an excellent book by Steven and Felix Halim, which is the reason why I use this particular OJ - since the book gives a course of competitive programming techniques and exercises relying on the problemset presented on UVa OJ. So if you are like me and occasionally solve some problems from UVa OJ - this below CLI utilities might be useful to you to save some time.
