bin -prefix zip delta word list compressor/decompressor


precat [-dzhLV] [-cfksSq] [file ...]


prezip is a a prefix delta compressor. It is not a general purpose compressor and should only be used on sorted word lists or other similar text files. It will likely increase the size of binary data.

If invoked as prezip, the default action is to compress. If invoked as preunzip, the default action is to decompress. If invoked as precat, the default action is to decompress to stdout.

If no file names are given then prezip will compress or decompress from the standard input to the standard output. Short flags can be combined so that "-c -s" is the same as "-cs".
