description         Python wrapper for ${github.project}
long_description    SentencePiece is an unsupervised text tokenizer \
                    and detokenizer mainly for Neural Network-based \
                    text generation systems where the vocabulary size \
                    is predetermined prior to the neural model \
                    training. SentencePiece implements subword units \
                    (e.g., byte-pair-encoding (BPE) \[Sennrich et al.\]) \
                    and unigram language model \[Kudo.\]) with the \
                    extension of direct training from raw \
                    sentences. SentencePiece allows us to make a \
                    purely end-to-end system that does not depend on \
                    language-specific pre/postprocessing.
