DESCRIPTION
Generates a context set from an input LM.

SYNOPSIS
ngramcontext [--options] [in.fst] [out.fst]

OPTIONS

--bigram_threshold: type = double, default = 1.1

    Bin overfill to force a bigram context split

--contexts: type = int64, default = 1

    Number of desired contexts

--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

    Enable garbage collection of cache

--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_relabel_opairs: type = string, default = ""

    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.
