o rZh[@s,dZddlZddlmZGdddeZdS)a The tok-tok tokenizer is a simple, general tokenizer, where the input has one sentence per line; thus only final period is tokenized. Tok-tok has been tested on, and gives reasonably good results for English, Persian, Russian, Czech, French, German, Vietnamese, Tajik, and a few others. The input should be in UTF-8 encoding.
