Compile (weighted) regular expressions into transducer(s) Common options:

Print version info
Print verbosely while processing
Only print fatal erros and requested output
Alias of --quiet

Input/Output options:

Read input transducer from INFILE
Write output transducer to OUTFILE

Map EPS as zero, i.e. epsilon.
symbols in composition (default is false).

Encode weights when minimizing (default is false).
Determinize result instead of minimizing it.

If OUTFILE or INFILE is missing or -, standard streams will be used. FMT must be one of the following: {foma, sfst, openfst-tropical, openfst-log}. If EPS is not defined, the default representation of 0 is used VALUEs recognized are {true,ON,yes} and {false,OFF,no}. Xfst variables are {flag-is-epsilon (default OFF)}.


create transducer {cat}:{dog}
same but with weight 3
same but with weight 3 in the middle
create transducers
"cat" and "dog" and "3"
