SYNOPSIS

       farextract [OPTIONS] [in1.far in2.far...]

DESCRIPTION

       Extracts FSTs from a finite-state archive.

OPTIONS

       Boolean  options  accept  either true or false as a value, or the implicit value true if neither value is
       specified.

       --filename_prefix=STRING
              Set the prefix to prepend to filenames.  Default: no prefix.

       --filename_suffix=STRING
              Set the suffix to append to filenames.  Default: no suffix.

       --fst_align[=BOOLEAN]
              Write FST data aligned where appropriate.  Default: false.

       --fst_compat_symbols[=BOOLEAN]
              Require symbol tables to match when appropriate.  Default: true.

       --fst_default_cache_gc[=BOOLEAN]
              Enable garbage collection of cache.  Default: true.

       --fst_default_cache_gc_limit=N
              Set the cache byte size that triggers garbage collection.  Default: 1048576.

       --fst_error_fatal[=BOOLEAN]
              If true, FST errors are fatal.  Otherwise, returned objects are flagged as bad.  For example, FSTs
              are returned with the kError property set to true, and FST weights set so  that  Member()  returns
              false.  Default: true.

       --fst_field_separator=STRING
              Set the characters used as a separator between printed fields.  Default: "     ".

       --fst_read_mode=STRING
              Set the default file reading mode for mappable files, either "read" or "map".  Default: "read".

       --fst_verify_properties[=BOOLEAN]
              Verify fst properties queried by TestProperties.  Default: false.

       --fst_weight_parentheses=STRING
              Set  the  characters  enclosing the first weight of a printed composite weight (e.g., pair weight,
              tuple weight, and derived classes) to ensure proper I/O of nested composite  weights.   Must  have
              size 0 (none) or 2 (open and close parenthesis).  Default: no parentheses.

       --fst_weight_separator=CHARACTER
              Set the character separator between printed composite weights.  Default: comma.

       --generate_filenames=N
              Generate N digit numeric filenames.  Default: use keys.

       --help[=BOOLEAN]
              Show usage information.  Default: false.

       --helpshort[=BOOLEAN]
              Show brief usage information.  Default: false.

       --keys=KEYS
              Extract  a  set  of  keys.  Ranges of keys are separated by --range-delimiter.  Distinct groups of
              keys are separated by --key-separator.

       --key-separator=CHARACTER
              Set the character separator between groups of keys.  Default: comma.

       --range-delimiter=CHARACTER
              Set the character separator between the start and end keys of a range.  Default: hyphen.

       --save_relabel_ipairs=FILENAME
              Save input relabel pairs to file.  Default: do not save.

       --save_relabel_opairs=FILENAME
              Save output relabel pairs to file.  Default: do not save.

       --tmpdir=PATHNAME
              Set the temporary directory to use.  Default: /tmp.

       --v[=N]
              Set the verbosity level.  Default: 0.
