Eevee is a local OI(and perhaps ACM in the future) judger for Linux. It is orignially designed to be used in Vulpix - the Online Judge, but tend to be standalone. Eevee contains two main parts: 1. caretaker - the program runner. A simple sandbox using setuid, chroot, setrlimit, etc. - module for limiting system call added by LX(http://lix.li). 2. comparer - the result judger. A simple file comparer with OI style (ignoring blanks on the line end and file end). (More things are in plan.) Eevee is free software, written by Hexcles Ma (http://robotshell.org).
