dictzip binary package in Ubuntu Jammy ppc64el

 This package provides a utility to compress dictionary databases with the
 LZ77 algorithm in a manner which is completely compatible with gzip(1),
 but using an extension that allows for random access to chunks
 of about 57kB without the overhead of decompressing the entire file.
 .
 This package also includes dictunzip, to decompress dictzipped files,
 and dictzcat, for viewing dictzipped files.
