Binary package “dictzip” in ubuntu bionic

compression utility for dictionary databases

 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.
