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.
