PREZIP-BIN(1)			 Aspell Abbreviated User's Manual		    PREZIP-BIN(1)

NAME
       prezip-bin - prefix zip delta word list compressor/decompressor

SYNOPSIS
       prezip-bin [ -V | -d | -z ]

DESCRIPTION
       prezip-bin  compresses/decompresses sorted word lists from standard input to standard out-
       put.

       Prezip-bin is similar to word-list-compress(1) but it allows a  larger  character  set  of
       {0x00...0x09,  0x0B,  0x0C,  0x0E...0xFF}  and  multi-words  larger than 255 characters in
       length.	It can also decompress word-list-compress(1) compatible files.

COMMANDS
       Prezip-bin accepts only one of these commands.

       -V     Display prezip-bin version number to standard output.

       -d     Read a compressed word list from standard input and decompress it to standard  out-
	      put.  This can be a word-list-compress(1) or a prezip-bin compressed file.

       -z     Read a binary word list from standard input and compress it to standard output.

EXAMPLES
       prezip-bin -d <wordlist.cwl >wordlist.txt
	      Decompress file wordlist.cwl to text file wordlist.txt

       prezip-bin -z <wordlist.txt >wordlist.pz 2>errors.txt
	      Compress	wordlist.txt  to binary file wordlist.pz and send any error messages to a
	      text file named errors.txt

       LC_COLLATE=C sort -u <wordlist.txt | prezip-bin -z >wordlist.pz
	      Sort a word list, then  pipe  it	to  prezip-bin	to  create  a  compressed  binary
	      wordlist.pz file.

       prezip-bin -d <words.pz | aspell create master ./words.rws
	      Decompress a wordlist, then pipe it to aspell(1) to create a spelling list.  Please
	      check the aspell(1) info manual for proper usage and options.

TIPS
       Prezip-bin is best used with sorted word list type files.  It is  not  a  general  purpose
       compression program since resulting files may actually increase in size.

       Unlike  word-list-compress(1)  if  your word list has leading or trailing blank spaces for
       formatting purposes, you should remove them first before  you  compress	your  list  using
       prezip-bin -z , otherwise those spaces will be included in the compressed binary output.

DIAGNOSTICS
       Prezip-bin normally exits with a return code of 0. If it encounters an error, a message is
       sent to standard error output (stderr), and prezip-bin exits with a non-zero return value.
       Error messages are listed below:

       (display help/usage message)
	      Unknown command given on the command line so prezip-bin displays a usage message to
	      standard error output.

       unknown format
	      The input file appears not to be an expected format, or  may  possibly  be  a  more
	      advanced format.	The output file will be empty.

       corrupt input
	      This  is	only for the decompression command -d. The input file appeared to be of a
	      correct format, but something appears wrong now.	There may be some valid  data  in
	      output, but due to input corruption, the rest of the file can not be completed.

       unexpected EOF
	      The  input  file appeared okay but ended sooner than expected, therefore the output
	      file is not complete.
