--help: type = bool, default = false
show usage information
--helpshort: type = bool, default = false
show brief usage information
--tmpdir: type = string, default = "/tmp"
temporary directory
--v: type = int32, default = 0
verbose level

--fst_align: type = bool, default = false
Write FST data aligned where appropriate
--fst_default_cache_gc: type = bool, default = true

--fst_default_cache_gc_limit: type = int64, default = 1048576
Cache byte size that triggers garbage collection
--fst_read_mode: type = string, default = "read"
Default file reading mode for mappable files
--fst_verify_properties: type = bool, default = false
Verify fst properties queried by TestProperties
--fst_weight_parentheses: type = string, default = ""
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)
--fst_weight_separator: type = string, default = ","
Character separator between printed composite weights; must be a single character
--save_relabel_ipairs: type = string, default = ""
Save input relabel pairs to file

Save output relabel pairs to file

--end_symbol: type = string, default = "</s>"
Class label for sentence start
--start_symbol: type = string, default = "<s>"
Class label for sentence start

--fst_compat_symbols: type = bool, default = true
Require symbol tables to match when appropriate
--fst_field_separator: type = string, default = " "
Set of characters used as a separator between printed fields

--fst_error_fatal: type = bool, default = true
FST errors are fatal; o.w. return objects flagged as bad:
e.g., FSTs - kError prop. true, FST weights - not a Member()
--ngram_error_fatal: type = bool, default = true
NGram errors are fatal; o.w. return objects flagged as bad:
e.g., NGramModel::Error() returns true.
