fstinfo \- show information about an FST
.SH "SYNOPSIS"

[\fIOPTIONS\fP] [\fIin.fst\fP]
.SH "DESCRIPTION"
.PP
Prints out information about an FST.
.SH "OPTIONS"
.PP
Boolean options accept either \fItrue\fP or \fIfalse\fP as a value, or the
implicit value \fItrue\fP if neither value is specified.
.TP
\fB\-\-arc_filter=\fITYPE\fP
Set the arc filter, one of \fIany\fP, \fIepsilon\fP, \fIiepsilon\fP, and
\fIoepsilon\fP.  This only affects the counts of (co)accessible states,
connected states, and (strongly) connected components.  Default: \fIany\fP.
.TP
\fB\-\-fst_align\fP[=\fIBOOLEAN\fP]
Write FST data aligned where appropriate.  Default: false.
.TP
\fB\-\-fst_compat_symbols\fP[=\fIBOOLEAN\fP]
Require symbol tables to match when appropriate.  Default: true.
.TP
\fB\-\-fst_default_cache_gc\fP[=\fIBOOLEAN\fP]
Enable garbage collection of cache.  Default: true.
.TP
\fB\-\-fst_default_cache_gc_limit\fP=\fIN\fP
Set the cache byte size that triggers garbage collection.  Default: 1048576.
.TP
\fB\-\-fst_error_fatal[=\fIBOOLEAN\fP]
If true, FST errors are fatal.  Otherwise, returned objects are flagged as bad.
For example, FSTs are returned with the \fIkError\fP property set to true, and
FST weights set so that \fIMember()\fP returns false.  Default: true.
.TP
\fB\-\-fst_field_separator\fP=\fISTRING\fP
Set the characters used as a separator between printed fields.  Default:
"	 ".
.TP
\fB\-\-fst_read_mode\fP=\fISTRING\fP
Set the default file reading mode for mappable files, either "read" or "map".
Default: "read".
.TP
\fB\-\-fst_verify[=\fIBOOLEAN\fP]
Verify FST sanity.  Default: true.
.TP
\fB\-\-fst_verify_properties\fP[=\fIBOOLEAN\fP]
Verify fst properties queried by TestProperties.  Default: false.
.TP
\fB\-\-fst_weight_parentheses\fP=\fISTRING\fP
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.
.TP
\fB\-\-fst_weight_separator\fP=\fICHARACTER\fP
Set the character separator between printed composite weights.  Default: comma.
.TP
\fB\-\-help\fP[=\fIBOOLEAN\fP]
Show usage information.  Default: false.
.TP
\fB\-\-helpshort\fP[=\fIBOOLEAN\fP]
Show brief usage information.  Default: false.
.TP
\fB\-\-info_type=\fITYPE\fP
Set the info format, one of \fIauto\fP, \fIlong\fP, and \fIshort\fP.  Default:
\fIauto\fP.
.TP
\fB\-\-pipe\fP[=\fIBOOLEAN\fP]
Send information to stderr, and input to stdout.  Default: false.
.TP
\fB\-\-save_relabel_ipairs\fP=\fIFILENAME\fP
Save input relabel pairs to file.  Default: do not save.
.TP
\fB\-\-save_relabel_opairs\fP=\fIFILENAME\fP
Save output relabel pairs to file.  Default: do not save.
.TP
\fB\-\-test_properties\fP[=\fIBOOLEAN\fP]
Compute property values (if unknown to FST).  Default: true.
.TP
\fB\-\-tmpdir\fP=\fIPATHNAME\fP
Set the temporary directory to use.  Default: /tmp.
.TP
\fB\-\-v\fP[=\fIN\fP]
Set the verbosity level.  Default: 0.
