OpenFst - Release 1.3
OpenFst is a library for constructing, combining, optimizing, and
searching weighted finite-state transducers (FSTs).
REQUIREMENTS:
  This version is known to work under Linux, MacOS, and Solaris using 
  g++ (>= 4.1). Expected to work wherever adequate POSIX (dlopen, ssize_t, 
  basename), c99 (snprintf, strtoll, <stdint.h>), and tr1 (<tr1/ordered_set>, 
  <tr1/ordered_map>) 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-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'. 
  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.
