+### Version 1.1
+# written by Pidong Wang, based on the code written by Josh Schroeder and Philipp Koehn
+# Version 1.1 updates:
+#       (1) add multithreading option "-threads NUM_THREADS" (default is 1);
+#       (2) add a timing option "-time" to calculate the average speed of this tokenizer;
+#       (3) add an option "-lines NUM_SENTENCES_PER_THREAD" to set the number of lines for each thread (default is 2000), and this option controls the memory amount needed: the larger this number is, the larger memory is required (the higher tokenization speed);
