            "content": "prezip-bin compresses/decompresses sorted word lists from standard input to standard output.\n\nPrezip-bin  is  similar  to  word-list-compress(1)  but  it  allows a larger character set of\n{0x00...0x09, 0x0B, 0x0C, 0x0E...0xFF} and multi-words larger than 255 characters in  length.\nIt can also decompress word-list-compress(1) compatible files.\n",

It is not a general purpose com‐\npression program since resulting files may actually increase in size.\n\nUnlike word-list-compress(1) if your word list has leading or trailing blank spaces for  for‐\nmatting purposes, you should remove them first before you compress your list using prezip-bin\n-z , otherwise those spaces will be included in the compressed binary output.\n",
