OpenFst - Release 1.4

OpenFst is a library for constructing, combining, optimizing, and
searching weighted finite-state transducers (FSTs).

REQUIREMENTS:
  This version is known to work under Linux and MacOS using g++ (>= 4.6).
  Expected to work wherever adequate POSIX (dlopen, ssize_t,
  basename), c99 (snprintf, strtoll, <stdint.h>), and C++11 (<unordered_set>,
  <unordered_map>, <forward_list>) support are available.

INSTALLATION:
  Follow the generic GNU build system instructions in ./INSTALL.  We
  recommend configuring with --enable-static=no for faster
  compiles.

  Optional features:
  --enable-bin             Build fst::script and command-line binaries (def: yes)
  --enable-compact-fsts    Enable all CompactFst classes (def: no)
  --enable-const-fsts      Enable all ConstFst classes (def: no)
  --enable-far		   Enable FAR (FST Archive) extension (def: no)
  --enable-linear-fsts     Enable Linear{Tagger,Classifier} Fst extensions (def: no)
  --enable-lookahead-fsts  Enable LookAheadFst classes (def: no)
  --enable-ngram-fsts      Enable NGramFst classes (def: no)
  --enable-pdt             Experimental push-down transducer extensions (def: no
)

  Configuring with --enable-bin=no gives very fast compiles, but
  excludes the command line utilities.

  Compiling with '-Wall -Wno-sign-compare' under g++ should give no
  warnings from this library.

USAGE:
  Assuming you've installed under the default /usr/local, the FST
  binaries are found on /usr/local/bin.

  To use in your own program, include <fst/fstlib.h> and compile
  with '-I /usr/local/include'. The compiler must support C++11
  (for g++ add the flag "-std=c++0x"). Link against /usr/local/lib/libfst.so
  and -ldl. Set your LD_LIBRARY_PATH (or equivalent) to contain /usr/local/lib.


  The linking is, by default, dynamic so that the Fst and Arc type DSO
  extensions can be used correctly if desired. Any extensions will
  be found under /usr/local/include/fst/extensions and /usr/local/lib/fst.
