  // 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.
