      STACKER DEVELOPER'S TOOL KIT
      Your software's access to the most advanced data compression 
      available
      
      Features:
      ---------
      
           High Performance Stacker LZSTM Lossless Compression Engines
           -----------------------------------------------------------
      
                50% faster (0.5 MB/sec) than Stac's previous software
                compression engines (the LZS221 compression libraries).
      
                LZS Server aware providing transparent access to 
                Stacker's compression engine (1 MB/sec) and Stacker LZS 
                coprocessors (up to 12 MB/sec) supplying the fastest 
                lossless compression available.
      
                2 to 1 average compression ratio.
      
                9 levels of compression vs. speed performance tuning.
      
                QIC-122 compatible.  Supports the QIC-40, QIC-80, 
                QIC-3010, and QIC-3020 tape formats.  Registered with 
                IETF, and ANSI.
      
                Compressed data format fully compatible with Stac's 
                LZS221 compression libraries (available for 80x86, 
                68000, i960, 386 flat protected mode, and C) and Stac's 
                high speed compression chips for full cross platform 
                data portability.
      
           Direct Transfer of Compressed Data
           ----------------------------------
      
                Allows transfer of compressed data from Stacker drives
                directly to tape, across networks, over modems, or to 
                other media without decompress and recompress.
      
           Stacker Compatibility Functions
           -------------------------------
      
                7 Informational functions supplying over 60 items of
                information about Stacker and Stacker drives, including
                individual file compression ratios
      
                6 Functions for manipulating Stacker drives
                Includes tools for writing Stacker aware installation 
                programs 
                
                Discussion of testing considerations for Stacker aware
                software
