If OUTFILE or INFILE is missing or -, standard streams will be used. If FMT is not given, OpenFst's tropical format will be used. The possible values for FMT are { foma, openfst-tropical, openfst-log, sfst, optimized-lookup-weighted, optimized-lookup-unweighted }. If EPS is not given, @0@ will be used.

Space in transition symbols must be escaped as '@_SPACE_@' when using att format.
