Option --execute can be invoked many times. If FMT is not given, OpenFst's tropical format will be used. The possible values for FMT are { foma, openfst-tropical, openfst-log, sfst }. Readline library, if enabled when configuring, is used for input by default. Input files are always treated as UTF-8.

STREAM can be { input, output, both }. If not given, defaults to {both}. If input file is not specified with -F, input is read interactively line by line from the user. If you redirect input from a file, use --pipe-mode=input. --pipe-mode=output is ignored on non-windows platforms.
