// Djamé: version record added for history's sake.
// note to future updater: please add your changelog below

// Modified by Slav Petrov and Ryanc Mc Donald (for  the sancl 2012 shared task)
// ===>  making it less sensitive to punct POS errors leading to
// ===> mismatch of length

// Modified by Djamé Seddah (for the spmrl shared 2013 task)
// ===> making it able to cope with Arabic very long lines (byte wise)
// ===>  now limit is 50000 bytes, was 5000 (damn bug, if you ask me)
// ===> modified to cope with spmrl 2013 morpg features (suggested by thomas Muller from IMS)
// please check the constant macro section
// Correction of bug causing hard slowdown (due to max_word_in_sent set too high)
// former version was 78x slower than regular evalb.
