OpenFST: ASCII symbol table to binary symbol table

convert_syms.cc

#include <fst/fst.h>
#include <fst/symbol-table.h>

/*

Converts ASCII OpenFST symbol tables to binary symbol tables. To compile:

g++ -I/usr/local/lib/fst -L/usr/local/lib/fst -lfst -o convert_syms convert_syms.cc

Then, run:

./convert_syms ascii.syms.txt asci.syms.bin

No promises made vis-a-vis security, error handling, etc. etc.
