  SCTK Version: 2.4.10
  
  asclite compression algorithm update.
  
  This directory contains SCTK, the NIST Scoring Toolkit.  SCTK contains the 
  source code, documentation and example data for the following programs:
  
  	sclite   V2.10  - "Score Lite",
  	sc_stats V1.3  - sclite's Statistical Significance Comparison tool
  	rover    V0.1  - Recognition Output Voting Error Reduction
  	asclite  V1.10 - Multidimensional alignment replacement for sclite
  
  The distribution was initially written in ANSI C on a SUN Workstation.  To date,
  the code has been successfully compiled and tested on the following platforms:

   * compiled with warning messages, but successful self test
  ** compiled and ran, but test6, which uses GNU's diff for alignment fails.  The 
     use of DIFF for alignment is rarely used and the failure can be safely
     ignored.
  
  Read install.txt to compile and install the package.  UNIX-style manual pages 
  and 'HTML' formatted manuals are provided in the 'doc' directory.
  
  			Bundled Software:
  
  This version of SCTK includes the CMU-Cambridge Statistical Language Modeling 
  Toolkit v2.  Included in STCK is the complete source code tree and 
  documentation.  The toolkit has been included so that SCLITE can use a language 
  model to compute conditional word weights for word-weighted scoring.
  
  
  			Optional Software:
  
  To use the interactive installation for sclite, edit the file 
  src/sclite/config.sh at line 36, set the user_interaction=1 it will ask you 
  during the configuration (make config) if you want to use GNU diff instead of 
  sclite and CMU-Cambridge SLM for sclite.  Those choices are not recommended and 
  not used anymore.
  
  Sclite has the ability to use GNU's "diff" utility as an alternate string 
  alignment method.  The installer has the choice whether or not to include this 
  ability in the compiled version.  
  
  If the use of GNU's "diff" is desired, you will need GNU's "diff" utility from 
  their "diffutils" distribution version 2.7.  If you cannot locate this 
  distribution, it is available via anonymous ftp from the jaguar.ncsl.nist.gov 
  server.  The compressed tar file 'diffutils-2.7.tar.Z' is located in the 'pub' 
  directory.  When you install diff, make sure the executable is installed as: 
  "gdiff", "gnudiff" or "diffgnu".  The 'config.sh' script expects it to be 
  called one of these.
  
  Special Note to SGI owners: When installing GNU's "diff" make sure to call it 
  "gnudiff" or "diffgnu", if you use "gdiff" the executable name may be 
  overshadowed by a pre-existing executable.
  
  utf_filt is using SGML external software and modules like SGMLS perl module and 
  nsgmls program which have be updated and continued: OpenSP 
  (http://sourceforge.net/project/showfiles.php?group_id=2115&package_id=2869).  
  The version v1.5.2 of OpenSP have been tested and working with the current 
  version of utf_filt.
  
  Special Note to Cygwin users: It has been reported that compilation of 'rfilter1'
  can fail in some case, please read the OPTIONS part of the 'rfilter1/makefile' and
  adatp accordingly before retrying compilation.
  
  
  			64 bits Compilation
  
  With big alignments, sctk needs to be compiled in 64 bits.
  By default, the C/C++ software are compiled in 32 bits with the options (-Os) 
  but can be compiled in 64 bits, -m64 is added to the CFLAGS variable in:
  src/asclite/core/makefile
  src/asclite/test/makefile
  src/rfilter1/makefile
  src/sclite/makefile
  Example of CFLAGS:
  For OSX 10.4+: -fast -m64 -arch x86_64 -arch ppc64
