• BSSC (0.95 alpha) - Block-sorting compressor/decompressor

  Block-sorting compressor/decompressor, Version 0.95 alpha
  
  Usage: BSSC  inputfile outputfile [<switches>]
  
    <Switches>
      -bN     Set maximum blocksize in kb (def: -b2048, min: -b128, max: -b16383)
      -a      Disable automatic blocksize detection
      -e      Disable EOL filter
      -f      Disable FLT32 filter
      -l      Disable DELTA filter
      -z      Disable LZP preprocessing stage
      -w      Disable BWT stage
      -t      Replace BWT with ST 21 bit (faster for big blocks)
      -r      Disable RLE after-BWT stage
      -d      Disable DCE (Distance+Entropy Coding) stage
      -o      Do not omit BWT & RLE stages when outputsize > inputsize
      -s      Show statistics (time per stage)
  
  Example: BSSC e FILENAME_IN FILENAME_OUT -b1024aeflzr
    (set blocksize to 1 Mb and perform compression with BWT and DCE stages only)
  Memory requirements: to compress 8.125*N + 768 kb, to decompress 5*N
  

• WSL (0.01 alpha) - tiny open source fast compressor\decompressor - LZW Second Life

  WSL file compressor/decompressor, Version 0.01 alpha
  
  Usage: WSL  inputfile outputfile [<switches>]
  
    <Switches>
      -bN     Set maximum blocksize in kb  (def: -b64, min: -b1, max: -b16384)
      -dN     Set dictionary size in kb (def: -d32, min: -d1, max: -d64)
      -lN     Set search depth (def: -l4, min: -l1, max: -l50)
  Example: WSL e FILENAME_IN FILENAME_OUT -b128d32l1
    (set blocksize to 128kb and perform compression with 32kb dictionary
     and minimum search depth)
