// See www.openfst.org for extensive documentation on this weighted
// finite-state transducer library.
//
// The FST script interface permits users to interact with FSTs without knowing
// their arc type. It does this by mapping compile-time polymorphism (in the
// form of a arc-templated FST types) onto a shared virtual interface. It also
// supports arc extension via a DSO interface. Due to the overhead of virtual
// dispatch and registered function lookups, the script API is somewhat slower
// then library API provided by types like StdVectorFst, but has the advantage
// that it is designed not to crash (and to provide useful debugging
// information) upon common user errors like passing invalid indices or
// attempting comparison of incompatible FSTs. It is used both by the FST
// binaries and the Python extension.
//
// This header includes all of the FST script functionality.
